Research on early language input and socioeconomic status typically relies on correlations in small convenience samples. Using data from Baby's First Years, this paper assesses the causal impact of monthly, unconditional cash transfers on child‐directed speech and child vocalizations among a large, racially diverse sample of low‐income U.S. mothers and their 1‐year‐olds (N = 563; 48% girls; 2019–2020). The monthly, unconditional cash transfers did not impact mothers' child‐directed speech during a 10‐min at‐home play session (effect sizes range from −.08 to.02), though there was wide variability within this sample. Future work will assess the impact of the continued cash transfer on children's language input and development over time. [ABSTRACT FROM AUTHOR]

There is no relationship more vital than the one a child shares with their primary caregivers early in development. Yet many children worldwide are raised in settings that lack the warmth, connection, and stimulation provided by a responsive primary caregiver. In this study, we used data from the Bucharest Early Intervention Project (BEIP), a longitudinal study of institutionally‐reared and family‐reared children, to test how caregiving quality during infancy is associated with average EEG power over the first 3.5 years of life in alpha, beta, and theta frequency bands, and associations with later executive function (EF) at age 8 years. The sample comprised 189 children (129 institutionally‐reared; 60 family‐reared) who contributed data on observed caregiving quality during infancy (baseline; average age of 22 months), resting EEG power at baseline, 30, and 42 months, and performance‐based data on a series of EF tasks at 8 years. Using Bayesian estimation, observed caregiving quality at baseline was marginally linked with higher average alpha and beta power, and lower theta power, from baseline to 42 months. In turn, higher average beta power and lower average theta power were marginally associated with higher EF at 8 years. In indirect effects models, higher caregiving quality at baseline was associated with higher EF at 8 years, with a marginal indirect effect through average theta power from baseline to 42 months. Variation in the quality of the early caregiving environment may be associated with later executive function, which is partially underpinned by individual differences in brain activity during early childhood. Research Highlights: Examined associations between caregiving quality during infancy, brain activity during early childhood, and executive function during mid‐childhood in sample of never‐institutionalized and institutionally‐reared children.Significant associations between higher quality caregiving during infancy and higher executive function during middle childhood.Marginal associations between caregiving quality during infancy and brain activity during early childhood.Marginal associations between brain activity during early childhood and executive function during mid‐childhood.

Geodiversity—the diversity of abiotic features and processes of the Earth's surface and subsurface—is an increasingly used concept in ecological research. A growing body of scientific literature has provided evidence of positive links between geodiversity and biodiversity. These studies highlight the potential of geodiversity to improve our understanding of biodiversity patterns and to complement current biodiversity conservation practices and strategies. However, definitions of geodiversity in ecological research vary widely. This can hinder the progress of geodiversity–biodiversity research and make it difficult to synthesize findings across studies. We therefore call for greater awareness of how geodiversity is currently defined and for more consistent use of the term 'geodiversity' in biodiversity research. [ABSTRACT FROM AUTHOR]

Prenatal maternal internalizing psychopathology (depression and anxiety) and socioeconomic status (SES) have been independently associated with higher risk for internalizing and externalizing problems in children. However, the pathways behind these associations are not well understood. Numerous studies have linked greater right frontal alpha asymmetry to internalizing problems; however, findings have been mixed. Several studies have also linked maternal internalizing psychopathology to children's frontal alpha asymmetry. Additionally, emerging studies have linked SES to children's frontal alpha asymmetry. To date, only a limited number of studies have examined these associations within a longitudinal design, and the majority have utilized relatively small samples. The current preregistered study utilizes data from a large prospective study of young children (N = 415; Meanage = 7.27 years; Rangeage = 5–11 years) to examine the association between prenatal maternal internalizing symptoms, children's frontal alpha asymmetry, and behavior problems. Prenatal maternal internalizing symptoms did not predict children's frontal alpha asymmetry, and there was no association between frontal alpha asymmetry and behavior problems. However, mothers' internalizing symptoms during pregnancy predicted children's internalizing and externalizing outcomes. Non‐preregistered analyses showed that lower prenatal maternal SES predicted greater child right frontal alpha asymmetry and internalizing problems. Additional non‐preregistered analyses did not find evidence for frontal alpha asymmetry as a moderator of the relation between prenatal maternal internalizing psychopathology and SES to children's behavior problems. Future research should examine the impact of SES on children's frontal alpha asymmetry in high‐risk samples. [ABSTRACT FROM AUTHOR]

Objective: The study examined differences between induced error‐related theta activity (4–7 Hz) and error‐related negativity (ERN) in youth and their unique associations with task performance as well as anxiety and worry during real‐life stress a year later. We hypothesized that induced theta, but not the ERN, would predict task performance. We also hypothesized that induced theta would predict less anxiety and worries during situational stress a year later, while ERN would predict more anxiety and worries. Method: Participants included 76 children aged 8–13 years who completed a flanker task while electroencephalogram (EEG) and behavioral data (t0) were collected. Approximately 1 year later (t1), during the first COVID‐19 lockdown, 40 families from the original sample completed a battery of online questionnaires to assess the children's stress‐related symptoms (anxiety, negative emotions and worries). We employed an analytical method that allowed us to differentiate between induced error‐related theta and the evoked ERN. Results: Induced error‐related theta, but not ERN, was associated with behavioral changes during the task, such as post‐error speeding. Furthermore, induced error‐related theta, but not ERN, was prospectively associated with less anxiety, worries, and fewer negative emotions a year later during COVID‐19 lockdown. Conclusions: Findings suggest ERN and error‐related theta are dissociable processes reflecting error monitoring in youth. Specifically, induced error‐related theta is more robustly associated with changes in behavior in the laboratory and with less anxiety and worries in real‐world settings. While extensive literature demonstrates that enhanced error‐related negativity (ERN) reflects a risk factor for anxiety, our findings suggest that error‐related theta activity is dissociable from ERN and may serve as a protective factor among youth. Furthermore, these results suggest that the assessment of error‐related theta could comprise a complementary tool in developing novel assessment or intervention approaches for pediatric anxiety.

Behavioral inhibition (BI) is a temperamental style characterized by cautious and fearful behaviors in novel situations. The present multi‐method, longitudinal study examined whether young children's observed and parent‐reported BI in social versus non‐social contexts predicts different long‐term psychosocial outcomes. Participants (N = 279) were drawn from a longitudinal study of socioemotional development. BI in social contexts ("social BI") was measured via children's observed wariness toward unfamiliar adults and peers at 24 and 36 months and parents' reports of children's social fear/shyness at 24, 36, and 48 months. BI in non‐social contexts ("non‐social BI") was measured via children's observed fearful responses to masks and novel toys, and parents' reports of children's distress to non‐social novelty at 9 months and non‐social fear at 48 months. At 15 years, anxiety was assessed via adolescent‐ and parent‐reports, and global internalizing and externalizing problems were assessed via parent‐reports. Confirmatory factor analysis showed that a two‐factor model fit the BI data significantly better than a single‐factor model, providing evidence for the dissociation of BI in social versus non‐social contexts. Social BI was uniquely associated with adolescent social anxiety, whereas non‐social BI was specifically associated with adolescent separation anxiety. Neither social BI nor non‐social BI predicted global internalizing and externalizing problems, providing evidence for the specific relations between BI and anxiety problems. Together, these results suggest that young children's inhibited responses in social versus non‐social situations predict different subtypes of anxiety problems in adolescence, highlighting the multifaceted nature of BI and the divergent trajectories of different anxiety problems.

When children first meet a stranger, there is great variation in how much they will approach and engage with the stranger. While individual differences in this type of behavior—called social wariness—are well‐documented in temperament research, surprisingly little attention has been paid to the social groups (such as race) of the stranger and how these characteristics might influence children's social wariness. In contrast, research on children's social bias and interracial friendships rarely examines individual differences in temperament and how temperament might influence cross‐group interactions. The current study bridges the gap across these different fields of research by examining whether the racial group of an unfamiliar peer or adult moderates the association between temperament and the social wariness that children display. Utilizing a longitudinal dataset that collected multiple measurements of children's temperament and behaviors (including parent‐reported shyness and social wariness toward unfamiliar adults and peers) across early childhood, we found that 2‐ to 7‐year‐old children with high parent‐reported shyness showed greater social wariness toward a different‐race stranger compared to a same‐race stranger, whereas children with low parent‐reported shyness did not. These results point to the importance of considering racial group membership in temperament research and the potential role that temperament might play in children's cross‐race interactions. Research Highlights: Previous research on temperament has not considered how the race of strangers could influence children's social wariness.We find evidence that 2‐ to 7‐year‐old children with high parent‐reported shyness show greater social wariness toward a different‐race stranger compared to a same‐race stranger.These results point to the importance of considering racial group membership in temperament research.Our findings also suggest temperament may play a role in children's cross‐race interactions.

The ability to monitor performance during a goal‐directed behavior differs among children and adults in ways that can be measured with several tasks and techniques. As well, recent work has shown that individual differences in error monitoring moderate temperamental risk for anxiety and that this moderation changes with age. We investigated age differences in neural responses linked to performance monitoring using a multimodal approach. The approach combined functional MRI and source localization of event‐related potentials (ERPs) in 12‐year‐old, 15‐year‐old, and adult participants. Neural generators of two components related to performance and error monitoring, the N2 and ERN, lay within specific areas of fMRI clusters. Whereas correlates of the N2 component appeared similar across age groups, age‐related differences manifested in the location of the generators of the ERN component. The dorsal anterior cingulate cortex (dACC) was the predominant source location for the 12‐year‐old group; this area manifested posteriorly for the 15‐year‐old and adult groups. A fMRI‐based ROI analysis confirmed this pattern of activity. These results suggest that changes in the underlying neural mechanisms are related to developmental changes in performance monitoring. Our research shows that developmental differences occur in neural responses during performance monitoring, with more posterior brain areas showing activation in adults and anterior regions in 12‐ and 15‐year‐old subjects. The fMRI cluster of results showed large activation in the ACC across ages. Source localization of ERP responses identified the ACC as the generator of the N2 ERP in all age groups, whereas generators of the ERN component revealed that the ACC is active during error monitoring in adolescence, whereas more posterior areas (PCC) are active in adults.

Background: Prenatal exposure to air pollution increases the risk for psychiatric disorders characterized by internalizing problems. In this study, we examined the roles of shyness and anterior cingulate cortex (ACC) activity in the association between prenatal exposure to polycyclic aromatic hydrocarbons (PAH) and children's internalizing problems at 7–9 years old. Methods: Participants include 53 children (31 girls, 22 boys). Personal air monitoring was conducted over 48 continuous hours during the third trimester of pregnancy to measure 8 PAHs. Mothers reported children's shyness (Emotionality Activity Sociability Temperament Survey) at age 5 and internalizing problems (Child Behavior Checklist) at ages 7–9. ACC activity was measured by fMRI during the Simon Spatial Incompatibility task at ages 7–9. Results: Shyness mediated the association between prenatal PAH exposure and internalizing problems. Higher prenatal PAH exposure predicted increased shyness, which in turn predicted greater internalizing problems. Moreover, left ACC activity during the Simon task moderated the association between prenatal PAH exposure and internalizing problems. Prenatal PAH exposure predicted increased risk for internalizing problems only when children showed heightened left ACC activity during the resolution of cognitive conflict. Conclusions: Our study innovatively synthesizes the fields of developmental psychology and environmental health science to offer new insights into the risk factors for anxiety disorders. Facilitating the development of healthy reactive and regulatory processes may improve the developmental outcomes for children highly exposed to air pollution. [ABSTRACT FROM AUTHOR]

Extant research has produced conflicting findings regarding the link between social fearfulness and prosocial behavior, with some studies reporting negative relations and others reporting null effects. Furthermore, these studies have focused predominantly on toddlerhood, and few have examined prosociality between peers. The present study investigated whether the link between social anxiety and prosocial behavior (i.e., providing encouragement) varied depending on interpersonal and situational factors (i.e., one's familiarity with a peer, and the level of support sought by a peer, respectively). We tested this question using a multimethod approach, which included ecologically valid stress‐inducing task and dyadic design with a sample of 9‐ to 10‐year‐olds (N = 447). Results revealed that social anxiety was related negatively to providing encouragement among familiar and unfamiliar dyads. In familiar dyads, however, this main effect was qualified by an interaction with the level of support sought by one's peer. Compared to those low in social anxiety, children high in social anxiety provided relatively less encouragement in response to higher levels of support seeking from their peers. The findings are considered in relation to theorizing regarding the effect of overarousal on children's prosocial behavior. [ABSTRACT FROM AUTHOR]

Despite substantial evidence indicating a close link between action production and perception in early child development, less is known about how action experience shapes the processes of perceiving and anticipating others' actions. Here, we developed a novel approach to capture functional connectivity specific to certain brain areas to investigate how action experience changes the networks involved in action perception and anticipation. Nine‐ and‐12‐month‐old infants observed familiar (grasping) and novel (tool‐use) actions while their brain activity was measured using EEG. Infants' motor competence of both actions was assessed. A link between action experience and connectivity patterns was found, particularly during the anticipation period. During action anticipation, greater motor competence in grasping predicted greater functional connectivity between visual (occipital alpha) and motor (central alpha) regions relative to global levels of whole‐brain EEG connectivity. Furthermore, visual and motor regions tended to be more coordinated in response to familiar versus novel actions and for older than younger participants. Critically, these effects were not found in the control networks (frontal‐central; frontal‐occipital; parietal‐central; parietal‐occipital), suggesting a unique role of visual‐motor networks on the link between motor skills and action encoding. Highlights: Infants' motor development predicted functional connectivity patterns during action anticipation.Faster graspers, and older infants, showed a stronger ratio of visual‐motor neural coherence.Overall whole‐brain connectivity was modulated by age and familiarity with the actions.Measuring inter‐site relative to whole‐brain connectivity can capture specific brain‐behavior links.Measures of phase‐based connectivity over time are sensitive to anticipatory action.

Behavioral Inhibition is a temperament identified in the first years of life that enhances the risk for development of anxiety during late childhood and adolescence. Amongst children characterized with this temperament, only around 40 percent go on to develop anxiety disorders, meaning that more than half of these children do not. Over the past 20 years, research has documented within‐child and socio‐contextual factors that support differing developmental pathways. This review provides a historical perspective on the research documenting the origins of this temperament, its biological correlates, and the factors that enhance or mitigate risk for development of anxiety. We review as well, research findings from two longitudinal cohorts that have identified moderators of behavioral inhibition in understanding pathways to anxiety. Research on these moderators has led us to develop the Detection and Dual Control (DDC) framework to understand differing developmental trajectories among behaviorally inhibited children. In this review, we use this framework to explain why and how specific cognitive and socio‐contextual factors influence differential pathways to anxiety versus resilience.

EEG methods offer a promising approach to study the development of attention or attention‐related processes such as change‐detection and attentional capture. However, the development of these attention processes from early to middle childhood is not well understood. In the current study, we utilized a passive three‐stimulus oddball paradigm to examine age‐related changes in auditory change‐detection and attentional capture in a large sample of children across childhood (N = 475; 249 female, 226 male; Mage = 6.71; SDage = 2.22; Rangeage = 4.01–11.5 years). Conventional ERP analyses revealed no age‐related changes in change detection (mismatch negativity) and attentional capture (P3a) components, but we observed age‐related reductions in late automatic processing of auditory change (late discriminative negativity). However, when utilizing time‐frequency analyses, we observed developmental increases in frontocentral signal strength (power) and consistency (inter‐trial phase synchrony) in delta and theta bands in response to novel sounds. Such frontocentral delta/theta responses have been linked in prior work to cognitive control. To further examine this possibility, we examined relations with inhibitory control. Results revealed that increased consistency in theta in response to novel sounds was related to improved inhibitory control. Together, our results advance our understanding of the development of attention in childhood. Moreover, they demonstrate the contributions of time‐frequency approaches to studying neurocognitive development. Finally, our results highlight the utility of neuroimaging paradigms that have low cognitive and motor demands to study the development of psychological processes. We examined age‐related differences in the auditory attention processes of change‐detection and orienting across childhood. ERP analyses revealed few age‐related changes. In contrast, time‐frequency analyses showed increases in frontocentral signal strength and consistency in delta and theta bands. Moreover, time‐frequency measures, but not ERPs, were related to improved inhibitory control, suggesting that these measures of auditory attention might be related to top‐down processes. Our findings demonstrate the contributions of time‐frequency approaches to studying neurocognitive development. [ABSTRACT FROM AUTHOR]

Institutional rearing negatively impacts the development of children's social skills and executive functions (EF). However, little is known about whether childhood social skills mediate the effects of the foster care intervention (FCG) and foster caregiving quality following early institutional rearing on EF and social skills in adolescence. We examined (a) whether children's social skills at 8 years mediate the impact of the FCG on the development of EF at ages 12 and 16 years, and (b) whether social skills and EF at ages 8 and 12 mediate the relation between caregiving quality in foster care at 42 months and subsequent social skills and EF at age 16. Participants included abandoned children from Romanian institutions, who were randomly assigned to a FCG (n = 68) or care as usual (n = 68), and a never‐institutionalized group (n = 135). At ages 8, 12, and 16, social skills were assessed via caregiver and teacher reports and EF were assessed via the Cambridge Neuropsychological Test Automated Battery. Caregiving quality of foster caregivers was observed at 42 months. FCG predicted better social skills at 8 years, which in turn predicted better EF in adolescence. Higher caregiver quality in foster care at 42 months predicted better social skills at 8 and 12 years, and better EF at 12 years, which in turn predicted 16‐year EF and social skills. These findings suggest that interventions targeting caregiving quality within foster care home environments may have long‐lasting positive effects on children's social skills and EF.

We examined whether family care following early‐life deprivation buffered the association between stressful life events (SLEs) and executive functioning (EF) in adolescence. In early childhood, 136 institutionally reared children were randomly assigned to foster care or care‐as‐usual; 72 never‐institutionalized children served as a comparison group. At age 16 years, adolescents (n = 143; 54% female; 67.1% Romanian) self‐reported recent SLEs, completed a battery of memory and EF tasks, and completed a go/nogo task in which mediofrontal theta power (MFTP) was measured using electroencephalogram. More independent SLEs predicted lower EF and more dependent SLEs predicted lower MFTP, but only among adolescents with prolonged early deprivation. Findings provide preliminary evidence that family care following early deprivation may facilitate resilience against stress during adolescence on EF. [ABSTRACT FROM AUTHOR]

This study is the first to examine spectrum‐wide (1 to 250 Hz) differences in electroencephalogram (EEG) power between eyes open (EO) and eyes closed (EC) resting state conditions in 486 children. The results extend the findings of previous studies by characterizing EEG power differences from 30 to 250 Hz between EO and EC across childhood. Developmental changes in EEG power showed spatial and frequency band differences as a function of age and EO/EC condition. A 64‐electrode system was used to record EEG at 4, 5, 7, 9, and 11 years of age. Specific findings were: (1) the alpha peak shifts from 8 Hz at 4 years to 9 Hz at 11 years, (2) EC results in increased EEG power (compared to EO) at lower frequencies but decreased EEG power at higher frequencies for all ages, (3) the EEG power difference between EO and EC changes from positive to negative within a narrow frequency band which shifts toward higher frequencies with age, from 9 to 12 Hz at 4 years to 32 Hz at 11 years, (4) at all ages EC is characterized by an increase in lower frequency EEG power most prominently over posterior regions, (5) at all ages, during EC, decreases in EEG power above 30 Hz are mostly over anterior regions of the scalp. This report demonstrates that the simple challenge of opening and closing the eyes offers the potential to provide quantitative biomarkers of phenotypic variation in brain maturation by employing a brief, minimally invasive protocol throughout childhood. EEG resting state activity changes throughout childhood and is different in eyes open versus eyes closed conditions across the full EEG power spectrum. These differences in cortical activity measured by scalp EEG, using a brief, minimally invasive protocol, may provide quantitative biomarkers of phenotypic variation in brain maturation.

Background: Humans are ubiquitously exposed to air pollutants including polycyclic aromatic hydrocarbons (PAH). Although most studies of prenatal exposures have focused on psychopathology in childhood or adolescence, the effects of air pollutants on early emerging individual differences in reactivity and regulation are of growing concern. Our study is the first to report effects of prenatal exposure to PAH and maternal stress on infant reactivity and regulation. Methods: Participants included 153 infants (74 girls and 79 boys). Prenatal exposure to PAH was measured via personal air monitoring during the third trimester of pregnancy. Maternal perceived stress was measured via self‐report. We assessed infant orienting/regulation (OR), surgency (SE), and negative affectivity (NA) at 4 months using the Infant Behavior Questionnaire. We measured infant socioemotional outcomes at 12 months using the Brief Infant‐Toddler Social & Emotional Assessment Questionnaire. Results: Infants with higher prenatal PAH exposure and of mothers with higher stress had lower OR at 4 months, which predicted lower competence at 12 months. Infants with higher prenatal PAH exposure had lower SE at 4 months, which predicted more behavioral problems at 12 months. Prenatal exposure to PAH had no effects on infant NA at 4 months, although NA was associated with greater behavioral problems at 12 months. Conclusions: Infant reactivity and regulation, as early makers of child psychopathology, can facilitate timely and targeted screening and possibly prevention of disorders caused, in part, by environmental pollution. A multifaceted approach to improve environmental quality and reduce psychosocial stress is necessary to improve the developmental outcomes of children and most specially children from disadvantaged communities that disproportionately experience these environmental exposures.

Over the last 20 years, we have learned much about the extent to which early‐life deprivation affects the mental health of children and adolescents. This body of evidence comes predominantly from studies of children raised in institutional care. The Bucharest Early Intervention Project (BEIP) is the only randomized controlled trial designed to evaluate whether the transition to family‐based foster care early in development can ameliorate the long‐term impact of institutional deprivation on psychopathology during vulnerable developmental windows such as adolescence. In this review, we detail the extent to which early deprivation affects mental health during this period, the capacity of family‐based care to facilitate recovery from early deprivation, and the mechanisms underpinning these effects spanning social–emotional, cognitive, stress, and neurobiological domains. We end by discussing the implications and directions for the BEIP and other studies of youth raised in institutions. [ABSTRACT FROM AUTHOR]

The authors examined temperamental and sociocognitive predictors of socially anxious behavior from preschool to early adolescence. Children (N = 227; 59% male; 69% White) completed a speech task at ages 5, 7, 10, and 13 and socially anxious behaviors were coded. Behavioral inhibition (BI) was assessed at ages 2/3 and Theory of Mind (ToM) was assessed at age 4. Data collection occurred between 2003 and 2016. Three trajectories of socially anxious behavior were identified: high stable, average increasing, and low stable. Higher BI was related to the high stable trajectory, whereas lower ToM was related to the increasing trajectory of socially anxious behavior. There are heterogenous pathways of socially anxious behavior, which may be uniquely influenced by early temperamental and sociocognitive factors. [ABSTRACT FROM AUTHOR]

Objectives: To estimate the incidence of intrauterine device (IUD) malpositioning detected on three‐dimensional (3D) transvaginal ultrasound within 8 weeks of placement and identify risk factors for malpositioning. Methods: Retrospective study of women who had an IUD placed at a large obstetrics and gynecology practice from January 1, 2015, to December 31, 2020. All patients underwent two‐dimensional ultrasound at the time of insertion and routine three‐dimensional ultrasound within 8 weeks. Baseline characteristics and potential risk factors were compared between women with correctly positioned and malpositioned IUDs. Odds ratios were calculated by logistic regression to identify risk factors independently associated with malpositioning. Results: A total of 763 IUD placements were included, and 127 malpositioned IUDs were identified representing an overall rate of malpositioning of 16.6% (95% confidence interval [CI] 14.0–19.3) with 8.8% (95% CI 6.8–10.8) requiring removal. Patients with malpositioned IUD had higher rates of morbid obesity (13.4% versus 3.8%, adjusted odds ratio [aOR] 2.46, 95% CI 1.10–5.50), prior uterine window or rupture (9.0% versus 2.2%, aOR 2.78, 95% CI 1.06–7.30), copper IUD placement (64.2% versus 47.4%, aOR 1.99, 95% CI 1.31–3.03), and symptoms such as bleeding or pain at follow‐up (35.8% versus 20.1%, aOR 2.58, 95% CI 1.67–3.98). Parity, breastfeeding, difficult insertion, and uterine size and positioning were not significant. Conclusions: The incidence of malpositioned IUD within 8 weeks of placement on 3D ultrasound is 16.6%, with 8.8% requiring removal. Significant risk factors for malpositioning include morbid obesity, prior uterine window or rupture, and copper IUD placement. These findings support the importance of routine follow‐up 3D ultrasound after seemingly successful IUD placement. [ABSTRACT FROM AUTHOR]

Error monitoring allows individuals to monitor and adapt their behavior by detecting errors. Error monitoring is thought to develop throughout childhood and adolescence. However, most of this evidence comes from studies in late childhood and adolescence utilizing event-related potentials (ERPs). The current study utilizes time– frequency (TF) and connectivity analyses to provide a comprehensive examination of age-related changes in error-monitoring processes across early childhood (N = 326; 50.9% females; 4–9 years). ERP analyses indicated the presence of the error-related negativity (ERN) and error positivity (Pe) across all ages. Results showed no errorspecific age-related changes in the ERN and the Pe. However, TF analyses suggested error-related frontocentral responses in delta and theta signal strength (power), delta consistency (intertrial phase synchrony), and delta synchrony (interchannel phase synchrony) between frontrocentral and frontolateral clusters—all of which increased with age. Additionally, the current study examines the reliability and effect size estimates of the ERP and TF measures. For most measures, more trials were needed to achieve acceptable reliability than what is commonly used in the psychophysiological literature. Resources to facilitate the measurement and reporting of reliability are provided. Overall, findings highlight the utility of TF analyses and provide useful information for future studies examining the development of error monitoring. [ABSTRACT FROM AUTHOR]

Background: Social anxiety is amongst the most prevalent adolescent mental health problems; however, it is often unrecognized due to its comorbidity with other anxiety problems such as generalized anxiety. Thus, understanding the unique developmental pathways to social anxiety is critical for improving its prevention. We examined the pathway from maternal shyness, when children were 4 years old, to adolescents' social anxiety at age 15 through social wariness at age 7. We hypothesized that childhood social wariness would mediate the association between maternal shyness and social anxiety in adolescence. Methods: Participants (N = 291; 54% female) were followed from early childhood to adolescence. Mothers reported on their own shyness when children were 4 years old. Social wariness toward unfamiliar peers was observed in the laboratory at ages 4 and 7. Adolescent social anxiety and generalized anxiety were assessed via self‐report, parent‐report, and clinical diagnoses at age 15. Results: Maternal shyness was positively associated with adolescent social anxiety but not generalized anxiety at age 15. Higher levels of maternal shyness at age 4 predicted greater social wariness at age 7, which in turn predicted greater social anxiety but not generalized anxiety at age 15. Social wariness at age 7 partially mediated the association between maternal shyness and adolescent social anxiety. Conclusions: This study identifies a unique developmental pathway from maternal shyness to adolescent social anxiety. Findings suggest that childhood social wariness connects maternal shyness to adolescent social anxiety. [ABSTRACT FROM AUTHOR]

This study examined whether early institutional rearing and attachment security influence the quality and quantity of friendships at age 16 in 138 participants, including children abandoned to institutions in Bucharest, Romania, who were randomized to care as usual (n = 45, 26 female), or foster care (n = 47, 25 female), and a never‐institutionalized group (n = 46, 18 female). Adolescents in the foster care group with secure attachment to their foster mothers at 42 months were comparable to never‐institutionalized adolescents in having more friends and more positive behaviors with their friend during dyadic interactions, compared to the foster care group with insecure attachment and care as usual group. Interventions targeting early child–caregiver attachment relationships may help foster the ability to build positive friendships in adolescence. [ABSTRACT FROM AUTHOR]

The last decade has seen increased availability of mobile electroencephalography (EEG). These mobile systems enable researchers to conduct data collection "in‐context," reducing participant burden and potentially increasing diversity and representation of research samples. Our research team completed in‐home data collection from more than 400 twelve‐month‐old infants from low‐income backgrounds using a mobile EEG system. In this paper, we provide methodological and analytic guidance for collecting high‐quality, mobile EEG in infants. Specifically, we offer insights and recommendations for equipment selection, data collection, and data analysis, highlighting important considerations for selecting a mobile EEG system. Examples include the size of the recording equipment, electrode type, reference types, and available montages. We also highlight important recommendations surrounding preparing a nonstandardized recording environment for EEG collection, obtaining informed consent from parents, instructions for parents during capping and recording, stimuli and task design, training researchers, and monitoring data as it comes in. Additionally, we provide access to the analysis code and demonstrate the robustness of the data from a recent study using this approach, in which 20 artifact‐free epochs achieve good internal consistency reliability. Finally, we provide recommendations and publicly available resources for future studies aiming to collect mobile EEG. [ABSTRACT FROM AUTHOR]

Behavioral inhibition is a temperamental disposition to react warily when confronted by unfamiliar people, objects, or events. Behaviorally inhibited children are at greater risk of developing anxiety disorders later in life. Previous studies reported that individuals with a history of childhood behavioral inhibition exhibit abnormal activity in the hippocampus and amygdala. However, few studies have investigated the structural differences that may underlie these functional abnormalities. In this exploratory study, we evaluated rhesus monkeys exhibiting a phenotype consistent with human behavioral inhibition. We performed quantitative neuroanatomical analyses that cannot be performed in humans including estimates of the volume and neuron number of distinct hippocampal regions and amygdala nuclei in behaviorally inhibited and control rhesus monkeys. Behaviorally inhibited monkeys had larger volumes of the rostral third of the hippocampal field CA3, smaller volumes of the rostral third of CA2, and smaller volumes of the accessory basal nucleus of the amygdala. Furthermore, behaviorally inhibited monkeys had fewer neurons in the rostral third of CA2. These structural differences may contribute to the functional abnormalities in the hippocampus and amygdala of behaviorally inhibited individuals. These structural findings in monkeys are consistent with a reduced modulation of amygdala activity via prefrontal cortex projections to the accessory basal nucleus. Given the putative roles of the amygdala in affective processing, CA3 in associative learning and CA2 in social memory, increased amygdala and CA3 activity, and diminished CA2 structure and function, may be associated with increased social anxiety and the heritability of behavioral inhibition. The findings from this exploratory study compel follow‐up investigations with larger sample sizes and additional analyses to provide greater insight and more definitive answers regarding the neurobiological bases of behavioral inhibition.

Background: Adolescence has been proposed to be a period of heightened sensitivity to environmental influence. If true, adolescence may present a window of opportunity for recovery for children exposed to early‐life adversity. Recent evidence supports adolescent recalibration of stress response systems following early‐life adversity. However, it is unknown whether similar recovery occurs in other domains of functioning in adolescence. Methods: We use data from the Bucharest Early Intervention Project – a randomized controlled trial of foster care for children raised in psychosocially depriving institutions – to examine the associations of the caregiving environment with reward processing, executive functioning, and internalizing and externalizing psychopathology at ages 8, 12, and 16 years, and evaluate whether these associations change across development. Results: Higher quality caregiving in adolescence was associated with greater reward responsivity and lower levels of internalizing and externalizing symptoms, after covarying for the early‐life caregiving environment. The associations of caregiving with executive function and internalizing and externalizing symptoms varied by age and were strongest at age 16 relative to ages 8 and 12 years. This heightened sensitivity to caregiving in adolescence was observed in both children with and without exposure to early psychosocial neglect. Conclusions: Adolescence may be a period of heightened sensitivity to the caregiving environment, at least for some domains of functioning. For children who experience early psychosocial deprivation, this developmental period may be a window of opportunity for recovery of some functions. Albeit correlational, these findings suggest that it may be possible to reverse or remediate some of the lasting effects of early‐life adversity with interventions that target caregiving during adolescence.

Motivation influences cognitive control, particularly in childhood and adolescence. Previous work finds that the error‐related negativity (ERN), an event‐related potential (ERP) linked to cognitive control following errors, is influenced by social motivation. However, it is unclear whether the influences of social motivation on the ERN extend to stimulus‐locked neural correlates of cognitive control. This study reexamines how social motivation influences cognitive control in adolescence by exploring motivational influences on two stimulus‐locked ERPs; the N2 and P3. Adolescent girls (8–17 years of age) completed a flanker task under two different conditions. In the social condition, girls were led to believe that they were evaluated by a peer during a flanker task. In the nonsocial condition, girls completed a flanker task while evaluated by a computer. Results revealed that all girls exhibited a larger P3 in social as compared to nonsocial contexts, whereas the N2 was not different between contexts. In addition, the largest P3 enhancements were observed among younger girls. These findings suggest that social motivation influences some ERP components related to cognitive control, and such influences change across development. Additionally, findings suggest the importance of including multiple ERPs when interpreting the functional significance of motivation on cognitive control. [ABSTRACT FROM AUTHOR]

Early in life, greater exposure to diverse people can change the tendency to prefer one's own social group. For instance, infants from racially diverse environments show less preference for their own‐race (ingroup) over other‐race (outgroup) faces than infants from racially homogeneous environments. Yet how social environment changes ingroup versus outgroup demarcation in infancy remains unclear. A commonly held assumption is that early emerging ingroup preference is based on an affective process: feeling more comfortable with familiar ingroup than unfamiliar outgroup members. However, other processes may also underlie ingroup preference: Infants may attend more to ingroup than outgroup members and/or mirror the actions of ingroup over outgroup individuals. By aggregating 7‐ to 12‐month‐old infants' electroencephalography (EEG) activity across three studies, we disambiguate these different processes in the EEG oscillations of preverbal infants according to social environment. White infants from more racially diverse neighborhoods exhibited greater frontal theta oscillation (an index of top‐down attention) and more mu rhythm desynchronization (an index of motor system activation and potentially neural mirroring) to racial outgroup individuals than White infants from less racially diverse neighborhoods. Neighborhood racial demographics did not relate to White infants' frontal alpha asymmetry (a measure of approach‐withdrawal motivation) toward racial outgroup individuals. Racial minority infants showed no effects of neighborhood racial demographics in their neural responses to racial outgroup individuals. These results indicate that neural mechanisms that may underlie social bias and prejudices are related to neighborhood racial demographics in the first year of life. [ABSTRACT FROM AUTHOR]

Individuals with a behaviorally inhibited (BI) temperament are more likely to develop social anxiety. However, the mechanisms by which socially anxious behavior emerges from BI are unclear. Variation in different forms of top‐down control, specifically executive functions (EF), may play distinct roles and characterize differential pathways to social anxiety. Here 291 children were assessed for BI in toddlerhood (ages 2 and 3), parent‐reported inhibitory control and set shifting during middle childhood (age 7), and multidimensional assessment of socially anxious behavior completed during late childhood and early adolescence (ages 9 and 12). Structural equation modeling revealed that early variation in BI predicted the development of socially anxious behavior through either higher levels of parent‐reported inhibitory control or lower levels of parent‐reported set shifting. These data reinforce the notion that top‐down control does not uniformly influence relations between temperament and socially anxious behavior. These data suggest novel approaches to thinking about the role of EFs and social anxiety outcomes as children approach adolescence. [ABSTRACT FROM AUTHOR]

Background: Children reared in institutions experience profound deprivation that is linked to impairments in social communication (SC). However, little is known about the long‐term consequences of institutional rearing on SC through adolescence, and how SC deficits relate to broad‐spectrum psychopathology. It is also unclear whether early removal from deprivation and placement into socially enriched environments remediates these difficulties. Methods: Children reared in Romanian institutions from the Bucharest Early Intervention Project were randomly assigned to care as usual or foster care intervention in early childhood. An age‐ and sex‐matched group of never‐institutionalized children was also recruited. SC data from 208 children at age 8 and 129 children at 16 were collected using the Social Communication Questionnaire. Psychopathology was assessed as saved factor scores for general (P) and specific internalizing (INT) and externalizing (EXT) problems. We examined (a) whether institutional rearing is associated with continued SC deficits into adolescence; (b) whether early placement into foster care mitigates risk for SC problems; and (c) associations between SC and psychopathology from middle childhood (age 8) to adolescence (age 16). Results: Findings suggest that: (a) institutionally‐reared children have significantly more SC problems than never‐institutionalized children at age 16; (b) children placed into foster care early in life have fewer problems with reciprocal social interaction compared to those with prolonged institutional rearing; and (c) deficits in SC at age 8 partially account for the link between institutional rearing and general psychopathology at age 16. Conclusions: Early deprivation is associated with impairments in SC that persist into adolescence, with evidence for the remedial benefit of family‐based care in the domain of reciprocal social interaction. Moreover, deficits in SC among ever‐institutionalized children in middle childhood may increase the risk of broad‐spectrum psychopathology in adolescence, thus providing one putative target for early intervention to safeguard against later psychiatric problems.

Cognitive control develops rapidly over the first decade of life, with one of the dominant changes being a transition from reliance on 'as‐needed' control (reactive control) to a more planful, sustained form of control (proactive control). Although the emergence of proactive control is important for mature behavior, we know little about how this transition takes place, the neural correlates of this transition, and whether development of executive functions influences the ability to adopt a proactive control strategy. This study addresses these questions, focusing on the transition from reactive to proactive control in a cross‐sectional sample of 79 children—forty‐one 5‐year‐olds and thirty‐eight 9‐year‐olds. Children completed an adapted version of the AX‐Continuous Performance Task while electroencephalography was recorded and a standardized executive function battery was administered. Results revealed 5‐year‐olds predominantly employed reactive strategies, whereas 9‐year‐olds used proactive strategies. Use of proactive control was predicted by working memory ability, above and beyond other executive functions. Moreover, when enacting proactive control, greater increases in neural activity underlying working memory updating were observed; links between working memory ability and proactive control strategy use were mediated by such neural activity. These results provide convergent evidence that the transition from reactive to proactive control may be dependent on age‐related changes in neurocognitive indices of working memory and that working memory may influence adopting a proactive control strategy.

A major challenge for electroencephalograph (EEG) studies on pediatric populations is that large amounts of data are lost due to artifacts (e.g., movement and blinks). Independent component analysis (ICA) can separate artifactual and neural activity, allowing researchers to remove such artifactual activity and retain a greater percentage of EEG data for analyses. However, manual identification of artifactual components is time‐consuming and requires subjective judgment. Automated algorithms, like ADJUST and ICLabel, have been validated on adults, but to our knowledge, no such algorithms have been optimized for pediatric data. Therefore, in an attempt to automate artifact selection for pediatric data collected with geodesic nets, we modified ADJUST's algorithm. Our "adjusted‐ADJUST" algorithm was compared to the "original‐ADJUST" algorithm and ICLabel in adults, children, and infants on three different performance measures: respective classification agreement with expert coders, the number of trials retained following artifact removal, and the reliability of the EEG signal after preprocessing with each algorithm. Overall, the adjusted‐ADJUST algorithm performed better than the original‐ADJUST algorithm and no ICA correction with adult and pediatric data. Moreover, in some measures, it performed better than ICLabel for pediatric data. These results indicate that optimizing existing algorithms improves artifact classification and retains more trials, potentially facilitating EEG studies with pediatric populations. Adjusted‐ADJUST is freely available under the terms of the GNU General Public License at: https://github.com/ChildDevLab/MADE-EEG-preprocessing-pipeline/tree/master/adjusted_adjust_scripts. Currently, there are no automated independent component analysis artifact classification algorithms optimized for pediatric data. Therefore, we modified the ADJUST algorithm, which was originally optimized for adult data, in order to improve ADJUST's performance on developmental populations. The results show that optimizing a well‐established algorithm for pediatric data improves performance in this population without compromising performance on adult populations. [ABSTRACT FROM AUTHOR]

Compared to adult EEG, EEG signals recorded from pediatric populations have shorter recording periods and contain more artifact contamination. Therefore, pediatric EEG data necessitate specific preprocessing approaches in order to remove environmental noise and physiological artifacts without losing large amounts of data. However, there is presently a scarcity of standard automated preprocessing pipelines suitable for pediatric EEG. In an effort to achieve greater standardization of EEG preprocessing, and in particular, for the analysis of pediatric data, we developed the Maryland analysis of developmental EEG (MADE) pipeline as an automated preprocessing pipeline compatible with EEG data recorded with different hardware systems, different populations, levels of artifact contamination, and length of recordings. MADE uses EEGLAB and functions from some EEGLAB plugins and includes additional customized features particularly useful for EEG data collected from pediatric populations. MADE processes event‐related and resting state EEG from raw data files through a series of preprocessing steps and outputs processed clean data ready to be analyzed in time, frequency, or time‐frequency domain. MADE provides a report file at the end of the preprocessing that describes a variety of features of the processed data to facilitate the assessment of the quality of processed data. In this article, we discuss some practical issues, which are specifically relevant to pediatric EEG preprocessing. We also provide custom‐written scripts to address these practical issues. MADE is freely available under the terms of the GNU General Public License at https://github.com/ChildDevLab/MADE-EEG-preprocessing-pipeline. This article presents the Maryland Analysis of Developmental EEG (MADE) pipeline, an automated preprocessing pipeline for EEG data that can be used with EEG recorded with different systems, populations, levels of artifact contamination, and lengths of recording. MADE is based on MATLAB and includes customized features particularly useful for EEG data collected from pediatric populations. [ABSTRACT FROM AUTHOR]

The current study examined the interplay between children's dispositional anger and susceptibility to peers' influence in increasing children's risk‐taking behaviors. Participants in the current study were children from a larger study of temperament and social–emotional development who were followed across 9, 24, 36, 48, and 60 months. Dispositional anger was measured using mothers' reports across 9 and 48 months. At 60 months, children played a risk‐taking computer game in presence of an unfamiliar peer who watched the child play. The child's risk‐taking was assessed during the game as the unfamiliar peers' reactions were coded based on comments that were peer directed, reflective of praising the target child's performance, or object directed, indicative of excitement toward the game. A latent profile analysis revealed three longitudinal anger profiles across infancy to early childhood: high stable, average stable, and low stable anger. Results suggested that as peers' object‐directed comments predicted risk‐taking independent of children's anger, the association between peer‐directed comments and risk‐taking was dependent on children's dispositional anger. Specifically, when peers praised the target child's performance, children in the high stable anger profile showed increased risk‐taking propensity. Findings are discussed based on the importance of considering both temperamental characteristics and aspects of the peer context in relation to children's risk‐taking. [ABSTRACT FROM AUTHOR]

The Val158Met rs4680 single‐nucleotide polymorphism (SNP) at the catechol‐O‐methyltransferase (COMT) gene, primarily involved in dopamine breakdown within prefrontal cortex, has shown relations with inhibitory control (IC) in both adults and children. However, little is known about how COMT genotype relates to developmental trajectories of IC throughout childhood. Here, our study explored the effects of the COMT genotype (Val/Val, Val/Met, and Met/Met) on IC trajectories between the ages of 5 and 10 years. Children (n = 222) completed a Go/Nogo task at ages 5, 7, and 10; IC was characterized using signal detection theory to examine IC performance (d′) and response strategy (RS) (criterion). COMT genotype was not related to initial levels of IC performance and RS at age 5 or change in RS from ages 5 to 10. In contrast, COMT genotype was related to change in IC performance between 5 and 10 years. While Val/Val children did not differ from Val/Met children in development of IC performance, children with the Met/Met genotype exhibited more rapid development of IC performance when compared with Val/Met peers. These results suggest that COMT genotype modulates the development of IC performance in middle childhood. [ABSTRACT FROM AUTHOR]

The mechanisms that support infant action processing are thought to be involved in the development of later social cognition. While a growing body of research demonstrates longitudinal links between action processing and explicit theory of mind (TOM), it remains unclear why this link emerges in some measures of action encoding and not others. In this paper, we recruit neural measures as a unique lens into which aspects of human infant action processing (i.e., action encoding and action execution; age 7 months) are related to preschool TOM (age 3 years; n = 31). We test whether individual differences in recruiting the sensorimotor system or attention processes during action encoding predict individual differences in TOM. Results indicate that reduced occipital alpha during action encoding predicts TOM at age 3. This finding converges with behavioral work and suggests that attentional processes involved in action encoding may support TOM. We also test whether neural processing during action execution draws on the proto‐substrates of effortful control (EC). Results indicate that frontal alpha oscillatory activity during action execution predicted EC at age 3—providing strong novel evidence that infant brain activity is longitudinally linked to EC. Further, we demonstrate that EC mediates the link between the frontal alpha response and TOM. This indirect effect is specific in terms of direction, neural response, and behavior. Together, these findings converge with behavioral research and demonstrate that domain general processes show strong links to early infant action processing and TOM. [ABSTRACT FROM AUTHOR]

This study examined disruptions in caregiving, as well as the association of these disruptions, with cognitive, behavioral, and social outcomes at age 12 in a sample of 136 Romanian children who were abandoned to institutions as infants and who experienced a range of subsequent types of care. Children were found to experience significantly more caregiving disruptions (CGD) earlier in life than later in childhood. More frequent CGD predicted increases in externalizing and internalizing behavior problems at age 12. Results are discussed in terms of the association between CGD and the long-term development of children who have experienced institutional rearing. [ABSTRACT FROM AUTHOR]

Background: ADHD is a neurodevelopmental disorder with a complex pathogenesis. Individual differences in temperamental reactivity – in particular, anger reactivity – are predictive of ADHD. The goal of this study was to examine the moderating (maternal caregiving behaviors; MCB) and mediating (inhibitory control) variables of reactivity using a 9‐year multimethod prospective longitudinal design. Methods: Participants included 291 children (135 male; 156 female) who participated in a larger study of temperament and social‐emotional development. Anger reactivity was assessed by observation of facial anger during an arm restraint task, and MCB were observed during a series of semi‐structured mother–infant tasks, both at 9 months of age. Inhibitory control was assessed by performance on a go/no‐go task at 5 years of age. ADHD symptoms were assessed by parent and teacher report questionnaires at 7 and 9 years, respectively. Results: Anger reactivity and poor inhibitory control were predictive of later ADHD symptoms. Results supported a moderated mediation model, in which the indirect effects of anger reactivity on ADHD symptoms through inhibitory control were conditional on quality of early MCB. Inhibitory control mediated the effect of anger reactivity on ADHD symptoms, but only among children exposed to lower‐quality MCB. Conclusions: Infant anger reactivity exerts a direct effect on later ADHD from infancy, suggesting anger reactivity as a very early indicator of ADHD risk. Higher‐quality caregiving did not buffer against the direct risk of anger reactivity on ADHD but did buffer against the indirect risk by reducing the negative effect of anger reactivity on inhibitory control. Thus, in the developmental pathway from anger reactivity to ADHD, more sensitive, less intrusive parenting supports the development of protective mechanisms (i.e. inhibitory control) to remediate ADHD risk.

Background: Children with the temperament of behavioral inhibition (BI) face increased risk for social anxiety. However, not all children with BI develop anxiety symptoms. Inhibitory control (IC) has been suggested as a moderator of the pathway between BI and social anxiety. This study uses longitudinal data to characterize development of IC and tests the hypothesis that IC moderates associations between early BI and later social anxiety symptoms. Methods: Children completed a Go/Nogo task at ages 5, 7, and 10 years as part of a longitudinal study of BI (measured at 2–3 years) and social anxiety symptoms (measured at 12 years). To assess IC development, response strategy (criterion) and inhibitory performance (d′) were characterized using signal detection theory. Latent growth models were used to characterize the development of IC and examine relations among BI, IC parameters, and social anxiety symptoms. Results: IC response strategy did not change between 5 and 10 years of age, whereas IC performance improved over time. BI scores in toddlerhood predicted neither initial levels (intercept) nor changes (slope) in IC response strategy or IC performance. However, between ages 5 and 10, rate of change in IC performance, but not response strategy, moderated relations between BI and later parent‐reported social anxiety symptoms. Specifically, greater age‐related improvements in IC performance predicted higher levels of social anxiety in high BI children. Conclusions: IC development in childhood occurs independent of BI levels. However, rapid increases in IC performance moderate risk for social anxiety symptoms in children with BI. Implications for theory and practice are discussed. [ABSTRACT FROM AUTHOR]

There is growing evidence that activation of the motor system during observation of actions, a phenomenon first observed in non‐human primates, underlies action understanding and even communication. This review (a) examines the evidence on motor system activity as an underlying neural correlate of action understanding; (b) reviews the theoretical and empirical work linking action understanding and the development of communication, with a specific focus on the role that gestures play as an intermediary; and (c) discusses the research on and existing opportunities for understanding the link between the motor system and communication in both humans and non‐human primates, through the lens of action perception. Bringing together findings and perspectives from developmental social cognition in both humans and non‐human primates and applying recent neuroscientific perspectives will help to elucidate the processes underlying the ability to understand and communicate with others.

The efficacy of treating cesarean scar pregnancies and cervical pregnancies with the Cook® cervical ripening balloon catheter, in a multicenter office‐based setting is reported. Thirty‐eight women were treated. Insertion of the catheter was performed under real‐time ultrasound guidance. Patients received adjuvant systemic methotrexate, prophylactic oral antibiotics, and oral pain medication. Serum human chorionic gonadotropin and ultrasound scans were followed serially until resolution. Thirty‐seven patients were successfully treated, requiring no further procedures. We found that the Cook cervical ripening balloon technique is a simple, effective, outpatient, minimally invasive treatment with few complications noted in this expanded series.

Background: Attention‐deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder with origins early in life. There is growing evidence that individual differences in temperament reactivity are predictive of ADHD symptoms, yet little is known about the relations between temperament reactivity in early infancy and later ADHD symptoms or the combined effect of reactivity with early environmental factors on ADHD symptom development. Using a 9‐year prospective longitudinal design, this study tested the independent and interactive contributions of infant reactivity and maternal caregiving behaviors (MCB) on parent‐ and teacher‐reported childhood ADHD symptoms. Methods: Participants included 291 children (135 male; 156 female) who participated in a larger study of temperament and social–emotional development. Reactivity was assessed by behavioral observation of negative affect, positive affect, and motor activity during novel stimuli presentations at 4 months of age. MCB were observed during a series of semistructured mother–infant tasks at 9 months of age. Finally, ADHD symptoms were assessed by parent‐ and teacher‐report questionnaires at 7 and 9 years, respectively. Results: Reactivity was predictive of ADHD symptoms, but results were sex specific. For boys, infant motor activity was positively predictive of later ADHD symptoms, but only at lower quality MCB. For girls, infant positive affect was positively predictive of later ADHD symptoms at lower quality MCB, and—unexpectedly—infant positive affect and motor activity were negatively predictive of later ADHD symptoms at higher quality MCB. Conclusions: These results point to early parenting as a moderating factor to mitigate temperament‐related risk for later ADHD, suggesting this as a potential intervention target to mitigate risk for ADHD among reactive infants.

Abstract: Adolescence is a developmental period characterized by increased social motivation and a heightened concern of peer evaluation. However, little research has examined social influences on neural functioning in adolescence. One psychophysiological measure of motivation, the error‐related negativity (ERN), is an ERP following an error. In adults, the ERN is enhanced by contextual factors that influence motivation, such as social observation and evaluation. The current study examined relations among age and neural responses in social contexts in adolescence. Seventy‐six adolescent girls (9–17 years old) completed a flanker task under two different conditions. In the social condition, adolescent girls were informed that two other adolescents would be observing and providing feedback about their performance. In the nonsocial condition, adolescent girls completed a flanker task alone and were told feedback was computer generated. Results revealed that younger adolescents exhibited a larger ERN in social contexts than nonsocial contexts. In contrast, there were no differences in the ERN between contexts among older adolescents. In addition, enhancements of the ERN in social contexts among younger adolescents diminished the relation between the ERN and age. These findings suggest that the ERN is sensitive to social contexts in early adolescence, and developmental changes in the ERN may be partially explained by contextual factors that influence motivation.

Abstract: Utilizing multiple measures of interpretive biases, the current study examined the roles of toddlers’ behavioral inhibition (BI) and maternal supportive reactions to children's negative emotions in relation to children's interpretive biases across middle to late childhood. Toddlers’ BI was measured during several laboratory tasks (n = 248) at 2 and 3 years of age. Mothers reported on their reactions to children's negative emotional expressions when children were 7 years old (n = 203), and children's interpretations of social cues were assessed at 7 and 10 years of age (ns = 179 and 161, respectively). Toddlers with high levels of BI expressed less positivity toward social engagement with unfamiliar peers during discussion of ambiguous social situations. Further, children with high BI were less likely to attribute the cause of negative social situations to external factors, particularly when mothers were less accepting of children's negative emotional displays. Findings are discussed in terms of cognition related to the interpretation of ambiguous and threat‐related social situations among temperamentally at‐risk children. [ABSTRACT FROM AUTHOR]

Background: Experiences in early life lay the foundation for later development and functioning. Severe psychosocial deprivation, as experienced by children in early institutional care, constitutes an adverse experience with long‐term negative consequences. The Bucharest Early Intervention Project sought to examine the effects of foster care as an alternative to institutional care for abandoned infants in Romanian institutions. Methods: At a mean age of 22 months, institutionalized children were randomized to foster care or care as usual. At age 12 years, we followed‐up with 98 of these children (50 randomized to foster care), as well as assessed 49 never institutionalized comparison children. Adaptive functioning was assessed across seven domains—mental health, physical health, substance use, risk‐taking behavior, family relations, peer relations, and academic performance. Children at or above the threshold for adaptive functioning in at least six of seven domains were classified as having overall adaptive functioning in early adolescence. Results: Among all children who had experienced severe early deprivation, 40% exhibited adaptive functioning. Children randomized to foster care were significantly more likely to exhibit adaptive functioning at age 12 years than children in the care as usual condition (56% vs. 23%). In support of external validity, children who met the threshold for adaptive functioning at age 12 years had higher IQs and were more physiologically responsive to stress. Among children randomized to foster care, children placed prior to age 20 months were more likely to meet the threshold for adaptive functioning than those placed after this age (79% vs. 46%). Conclusions: This study provides causal evidence that placing children into families following severe deprivation increases the likelihood of adaptive functioning in early adolescence.

This study examined how timing (i.e., relative maturity) and rate (i.e., how quickly infants attain proficiency) of A-not-B performance were related to changes in brain activity from age 6 to 12 months. A-not-B performance and resting EEG (electroencephalography) were measured monthly from age 6 to 12 months in 28 infants and were modeled using logistic and linear growth curve models. Infants with faster performance rates reached performance milestones earlier. Infants with faster rates of increase in A-not-B performance had lower occipital power at 6 months and greater linear increases in occipital power. The results underscore the importance of considering nonlinear change processes for studying infants' cognitive development as well as how these changes are related to trajectories of EEG power.

Abstract: The adverse effects of institutionalized care and psychosocial deprivation have been documented for more than 100 years. Children who have been raised in institutions are at heightened risk of developing internalizing and externalizing disorders. Given the profound biological and psychological effects of institutional rearing, identifying neural and cognitive factors that influence the emergence of psychopathology in institutionalized children is of great interest. Using data from the Bucharest Early Intervention Project, a randomized control study on the effects of institutional care and a foster care intervention, this article examines two factors that appear to influence the emergence of psychopathology in children who have been institutionalized—neural indices of cognitive control and visual attention biases.

We examined visual recognition memory and executive functioning (spatial working memory [SWM], spatial planning, rule learning, and attention shifting) in 12-year-olds (n = 150) who participated in the Bucharest Early Intervention Project, a randomized controlled trial of foster care for institutionally reared children. Similar to prior reports at 8 years of age, institutionally reared children showed significant deficits in visual recognition memory and SWM. Deficits in attention shifting and rule learning were also apparent at this time point. These data suggest that early experiences continue to shape the development of memory, learning, and executive functioning processes in preadolescence, which may explain broader cognitive and learning difficulties commonly associated with severe early life neglect.

Background: The objective was to identify risk factors associated with blood transfusion in patients undergoing high-order Cesarean delivery (CD).Study Design and Methods: This was a retrospective cohort study of patients undergoing third or more CD by a single maternal-fetal medicine practice between 2005 and 2016. We compared risk factors between women who did and did not receive a red blood cell transfusion during the operation or before discharge. Repeat analysis was performed after excluding women with placenta previa.Results: A total of 514 patients were included, 18 of whom (3.5%; 95% confidence interval [CI], 2.2%-5.5%) received a blood transfusion. Placenta previa was the most significant risk factor for transfusion (61.1% of patients who received a transfusion vs. 1% of patients who did not; p < 0.001). Patients with a placenta previa had a 68.8% likelihood of requiring a blood transfusion. After women who had placenta previa were excluded, the incidence of blood transfusion was seven of 498 (1.4%; 95% CI, 0.7%-2.9%). Risk factors significantly associated with blood transfusion in the absence of previa were prophylactic anticoagulation during pregnancy and having labored. The incidence of transfusion in patients with no placenta previa, no anticoagulation, and no labor was 0.7% (95% CI, 0.3%-2.1%). Placenta previa was the most predictive risk factor for transfusion with a positive predictive value of 68.8% and a negative predictive value of 98.4%.Conclusion: In patients undergoing a third or more CD, only placenta previa, prophylactic anticoagulation during pregnancy, and having labored are independently associated with requiring a blood transfusion. These data can be used to guide physician ordering of prepared blood products preoperatively. [ABSTRACT FROM AUTHOR]
