We argue that natural language can be usefully described as quasi-compositional and we suggest that deep learning-based neural language models bear long-term promise to capture how language conveys meaning. We also note that a successful account of human language processing should explain both the outcome of the comprehension process and the continuous internal processes underlying this performance. These points motivate our discussion of a neural network model of sentence comprehension, the Sentence Gestalt model, which we have used to account for the N400 component of the event-related brain potential (ERP), which tracks meaning processing as it happens in real time. The model, which shares features with recent deep learning-based language models, simulates N400 amplitude as the automatic update of a probabilistic representation of the situation or event described by the sentence, corresponding to a temporal difference learning signal at the level of meaning. We suggest that this process happens relatively automatically, and that sometimes a more-controlled attention-dependent process is necessary for successful comprehension, which may be reflected in the subsequent P600 ERP component. We relate this account to current deep learning models as well as classic linguistic theory, and use it to illustrate a domain general perspective on some specific linguistic operations postulated based on compositional analyses of natural language. This article is part of the theme issue 'Towards mechanistic models of meaning composition'.

In this report, we illustrate the considerable impact of researcher degrees of freedom with respect to exclusion of participants in paradigms with a learning element. We illustrate this empirically through case examples from human fear conditioning research, in which the exclusion of 'non-learners' and 'non-responders' is common - despite a lack of consensus on how to define these groups. We illustrate the substantial heterogeneity in exclusion criteria identified in a systematic literature search and highlight the potential problems and pitfalls of different definitions through case examples based on re-analyses of existing data sets. On the basis of these studies, we propose a consensus on evidence-based rather than idiosyncratic criteria, including clear guidelines on reporting details. Taken together, we illustrate how flexibility in data collection and analysis can be avoided, which will benefit the robustness and replicability of research findings and can be expected to be applicable to other fields of research that involve a learning element. ispartof: ELIFE vol:8 ispartof: location:England status: published

This two-wave longitudinal study identified configurations of social rejection, affiliation with aggressive peers, and academic failure and examined their predictivity for reactive and proactive aggression in a sample of 1,479 children and adolescents aged between 9 and 19 years. Latent profile analysis yielded three configurations of risk factors, made up of a non-risk group, a risk group scoring high on measures of social rejection (SR), and a risk group scoring high on measures of affiliation with aggressive peers and academic failure (APAF). Latent path analysis revealed that, as predicted, only membership in the SR group at T1 predicted reactive aggression at T2 17 months later. By contrast, only membership in the APAF group at T1 predicted proactive aggression at T2.

Many studies demonstrated interactions between number processing and either spatial codes (effects of spatial-numerical associations) or visual size-related codes (size-congruity effect). However, the interrelatedness of these two number couplings is still unclear. The present study examines the simultaneous occurrence of space- and size-numerical congruency effects and their interactions both within and across trials, in a magnitude judgment task physically small or large digits were presented left or right from screen center. The reaction times analysis revealed that space- and size-congruency effects coexisted in parallel and combined additively. Moreover, a selective sequential modulation of the two congruency effects was found. The size-congruency effect was reduced after size incongruent trials. The space-congruency effect, however, was only affected by the previous space congruency. The observed independence of spatial-numerical and within magnitude associations is interpreted as evidence that the two couplings reflect Different attributes of numerical meaning possibly related to orginality and cardinality.

Two issues should be addressed to refine and extend the distinction between temporal updating and reasoning advocated by Hoerl & McCormack. First, do the mental representations constructed during updating differ from those used for reasoning? Second, are updating and reasoning the only two processes relevant to temporal thinking? If not, is a dual-systems framework sensible? We address both issues below.

Working memory (WM), which underlies the temporary storage and manipulation of information, is critical for multiple aspects of cognition and everyday life. Nevertheless, research examining WM specifically in older adults remains limited, despite the global rapid increase in human life expectancy. We examined WM in a large sample ( N = 754) of healthy older adults (aged 58-89) in a non-Western population (Chinese speakers) in Taiwan, on a digit n-back task. We tested not only the influence of age itself and of load (1-back vs. 2-back) but also the effects of both sex and education, which have been shown to modulate WM abilities. Mixed-effects regression revealed that, within older adulthood, age negatively impacted WM abilities (with linear, not nonlinear, effects), as did load (worse performance at 2-back). In contrast, education level was positively associated with WM. Moreover, both age and education interacted with sex. With increasing age, males showed a steeper WM decline than females; with increasing education, females showed greater WM gains than males. Together with other findings, the evidence suggests that age, sex, and education all impact WM in older adults, but interact in particular ways. The results have both basic research and translational implications and are consistent with particular benefits from increased education for women.

Turkish heritage students are underrepresented at university-track secondary schools in Germany, yet the institutional discrimination contributing to this ongoing disparity often remains unquestioned, situated within inequitable norms of belonging. Drawing on critical race theory and a risk and resilience framework, the current study investigated the interplay between institutional and interpersonal discrimination in relation to exclusionary norms enacted in university-track schools. Using thematic analysis, interviews with eight Turkish German young adults from multiple regions of Germany were analyzed, highlighting the need for culturally responsive teaching, more teacher reflexivity regarding bias, a greater focus on equity, and more direct discussions of racism and its impact.

Researchers examining the accuracy of observers ratings of others are devoting increased attention to peer-reported personality traits. Thus, the main purpose of this study was to investigate convergent validity of the three-factor Dark Triad model of personality framework, using two different rating methods: self-ratings and peer-ratings. Each participant (N = 266) was asked to collect three peer ratings (total peers N = 798). First, respondents completed three Dark Triad measures-Mach IV, SRP-III, and NPI-17 instruments. The peer-report forms of these instruments consisted of the same items as in the self-report version, but the rephrasing was appropriate to a third-person perspective. With the exception of one subscale of narcissism, Dark Triad measures demonstrated substantial convergent validity. These findings challenge views that at least two dark personality characteristics, i.e. psychopathy and Machiavellianism, are accurately observable phenomenon. The influences of agreement between self and other raters are discussed in relation to the degree of ratability and social desirability.

Spatial-numerical associations (SNAs) have been studied extensively in the past two decades, always requiring either explicit magnitude processing or explicit spatial-directional processing. This means that the typical finding of an association of small numbers with left or bottom space and of larger numbers with right or top space could be due to these requirements and not the conceptual representation of numbers. The present study compares explicit and implicit magnitude processing in an implicit spatial-directional task and identifies SNAs as artefacts of either explicit magnitude processing or explicit spatial- directional processing; they do not reveal spatial-conceptual links. This finding requires revision of current accounts of the relationship between numbers and space.

Novel concepts employing autologous, ex vivo expanded natural regulatory T cells (nTreg) for adoptive transfer has potential to prevent organ rejection after kidney transplantation. However, the impact of dialysis and maintenance immunosuppression on the nTreg phenotype and peripheral survival is not well understood, but essential when assessing patient eligibility. The current study investigates regulatory T-cells in dialysis and kidney transplanted patients and the feasibility of generating a clinically useful nTreg product from these patients. Heparinized blood from 200 individuals including healthy controls, dialysis patients with end stage renal disease and patients 1, 5, 10, 15, 20 years after kidney transplantation were analyzed. Differentiation and maturation of nTregs were studied by flow cytometry in order to compare dialysis patients and kidney transplanted patients under maintenance immunosuppression to healthy controls. CD127 expressing CD4(+)CD25(high)FoxP3(+) nTregs were detectable at increased frequencies in dialysis patients with no negative impact on the nTreg end product quality and therapeutic usefulness of the ex vivo expanded nTregs. Further, despite that immunosuppression mildly altered nTreg maturation, neither dialysis nor pharmacological immunosuppression or previous acute rejection episodes impeded nTreg survival in vivo. Accordingly, the generation of autologous, highly pure nTreg products is feasible and qualifies patients awaiting or having received allogenic kidney transplantation for adoptive nTreg therapy. Thus, our novel treatment approach may enable us to reduce the incidence of organ rejection and reduce the need of long-term immunosuppression.

Psychiatrische Stationen sind ein wichtiges Element in der psychiatrischen Versorgung von Menschen mit akuter Eigen- oder Fremdgefährdung. Leider kommt es in diesem Rahmen immer wieder auch zu Aggression, Gewalt (Konflikten) sowie zur Anwendung von Zwang (Eindämmung). Als entscheidender Faktor für den sachgemäßen Umgang mit diesen Situationen wird sowohl die Quantität als auch die Qualität der Mitarbeitenden angesehen. Vor diesem Hintergrund beschäftigt sich die vorliegende Untersuchung mit der Versorgungssituation auf akutpsychiatrischen Stationen. Die Hypothese lautet, dass sowohl die Größe der akutpsychiatrischen Station als auch die Anzahl der Pflegenden einen Einfluss auf das Vorkommen konflikthafter Situationen haben. Hierfür sind Daten in 6 Kliniken auf insgesamt 12 psychiatrischen Stationen erfasst worden. Als Erfassungsinstrument diente die Patient Staff Conflict Checklist – Shift Report (PCC-SR). Insgesamt konnten 2026 Schichten (Früh‑, Spät- und Nachtschicht) erfasst und ausgewertet werden. Die personelle Besetzung der Stationen mit Pflegepersonal variierte erheblich. Die Ergebnisse zeigen, dass sowohl die Stationsgröße als auch die Anzahl der Pflegepersonen auf akutpsychiatrischen Stationen einen signifikanten Einfluss auf das Vorkommen von Konflikten haben. In den Ergebnissen zeigt sich weiterhin, dass sich die Inzidenz des konflikthaften Verhaltens von Patienten sowohl im Hinblick auf die untersuchten Stationen der beteiligten Krankenhäuser als auch im Hinblick auf die betrachteten Dienstzeittypen unterscheiden. Darüber hinaus zeigt sich, dass das Ausmaß der Schließung einer Akutstation und die Größe einer Station einen negativen Einfluss auf die Inzidenz von Konflikten im stationär akutpsychiatrischen Kontext haben. Das Auftreten konflikthaften Verhaltens kann zur Fremd- oder Selbstgefährdung und zu einer Vielzahl deeskalierender und eindämmender Maßnahmen führen. Hierfür sind entsprechende personelle Ressourcen erforderlich. Acute psychiatric wards are an important element in the mental healthcare of people at risk for acute harm to others or self-harm. Unfortunately, aggression, violence (conflict) and the use of coercion (containment) are still part of psychiatric care. The decisive factor for the correct handling of these situations is the quantity as well as the quality of the employees. Therefore, the present study dealt with the care situation on acute psychiatric wards. The hypothesis is that both the number of beds on the acute psychiatric ward and the number of caregivers have an impact on the occurrence of conflict and containment. For this purpose, data were collected in 6 clinics on a total of 12 acute psychiatric wards. The Patient Staff Conflict Checklist - Shift Report (PCC-SR) was used as the data entry tool. A total of 2026 shifts (early, late and night shifts) were recorded and evaluated. The staffing of the wards with nursing personnel varied considerably. The results show that both the size of the ward and also the number of caregivers on acute psychiatric wards have a significant impact on the occurrence of conflicts. The results also show that the incidence of conflicting behavior of patients differs both in terms of the wards of the hospitals involved and in the type of service considered. In addition, it can be seen that the extent of closure of an acute ward (i.aEuroe. the closed ward or entrance door) and the size of a ward (i.aEuroe. the number of beds) have a negative impact on the incidence of inpatient acute psychiatric contexts. The occurrence of conflict behavior can lead to alien or self-endangerment and to a variety of de-escalating and containment measures. This requires appropriate human resources.

Background Cigarette smoking has severe adverse health consequences in adults and in the offspring of mothers who smoke during pregnancy. One of the most widely reported effects of smoking during pregnancy is reduced birth weight which is in turn associated with chronic disease in adulthood. Epigenome-wide association studies have revealed that smokers show a characteristic “smoking methylation pattern”, and recent authors have proposed that DNA methylation mediates the impact of maternal smoking on birth weight. The aims of the present study were to replicate previous reports that methylation mediates the effect of maternal smoking on birth weight, and for the first time to investigate whether the observed mediation effects are sex-specific in order to account for known sex-specific differences in methylation levels. Methods Methylation levels in the cord blood of 313 newborns were determined using the Illumina HumanMethylation450K Beadchip. A total of 5,527 CpG sites selected on the basis of evidence from the literature were tested. To determine whether the observed association between maternal smoking and birth weight was attributable to methylation, mediation analyses were performed for significant CpG sites. Separate analyses were then performed in males and females. Results Following quality control, 282 newborns eventually remained in the analysis. A total of 25 mothers had smoked consistently throughout the pregnancy. The birthweigt of newborns whose mothers had smoked throughout pregnancy was reduced by >200g. After correction for multiple testing, 30 CpGs showed differential methylation in the maternal smoking subgroup including top “smoking methylation pattern” genes AHRR, MYO1G, GFI1, CYP1A1, and CNTNAP2. The effect of maternal smoking on birth weight was partly mediated by the methylation of cg25325512 (PIM1); cg25949550 (CNTNAP2); and cg08699196 (ITGB7). Sex-specific analyses revealed a mediating effect for cg25949550 (CNTNAP2) in male newborns. Conclusion The present data replicate previous findings that methylation can mediate the effect of maternal smoking on birth weight. The analysis of sex-dependent mediation effects suggests that the sex of the newborn may have an influence. Larger studies are warranted to investigate the role of both the identified differentially methylated loci and the sex of the newborn in mediating the association between maternal smoking during pregnancy and birth weight.

Der Erwerb grundlegender arithmetischer Konzepte im Vorschul- und Grundschulalter (Altersbereich 4 bis 8 Jahre) lasst sich anhand eines kognitiv-entwicklungspsychologischen Modells mit 6 Niveaus beschreiben: (1) Zahlzahl, (2) ordinaler Zahlenstrahl, (3) Kardinalitat und Zerlegbarkeit, (4) Enthaltensein und Klasseninklusion, (5) Relationalitat und (6) Zahlen gleichmachtig bundeln. Im Artikel werden 3 Studien zur langsschnittlichen Prufung des Modells vorgestellt. In den Studien 1 (N = 26; altersheterogen) und 2 (N = 62; altershomogen) zeigt sich, dass die individuelle Entwicklung arithmetischer Konzepte uber 18 Monate (Studie 1: 4 Messzeitpunkte) bzw. 17 Monate (Studie 2: 3 Messzeitpunkte vor, am und nach dem Schuleintritt) den Niveaus des Modells folgt. In Studie 3 (N = 243) wird deutlich, dass der curriculare mathematische Kompetenzerwerb am Ende der Klassenstufe 2 deutlich besser durch das konzeptuell-arithmetische Verstandnis am Ende der Klassenstufe 1 vorhersagt wird als durch die Intelligenz. Die Ergebnisse untermauern die Validitat des Modells und belegen die Bedeutung grundlegender arithmetischer Konzepte fur mathematisches Lernen in der Schule mit entsprechenden Konsequenzen fur die gezielte Forderung rechenschwacher Kinder.

Even before formal schooling, children map numbers onto space in a directional manner. The origin of this preliterate spatial–numerical association is still debated. We investigated the role of enculturation for shaping the directionality of the association between numbers and space, focusing on counting behavior in 3- to 5-year-old preliterate children. Two studies provide evidence that, after observing reading from storybooks (left-to-right or right-to-left reading) children change their counting direction in line with the direction of observed reading. Just observing visuospatial directional movements had no such effect on counting direction. Complementarily, we document that book illustrations, prevalent in children's cultures, exhibit directionality that conforms to the direction of a culture's written language. We propose that shared book reading activates spatiotemporal representations of order in young children, which in turn affect their spatial representation of numbers.

The preferred viewing location in words [Rayner, K. (1979). Eye guidance in reading: Fixation locations within words. Perception, 8, 21–30] during reading is near the word centre. Parafoveal word length information is utilized to guide the eyes toward it. A recent study by Yan and colleagues [Yan, M., Zhou, W., Shu, H., Yusupu, R., Miao, D., Krügel, A., & Kliegl, R. (2014). Eye movements guided by morphological structure: Evidence from the Uighur language. Cognition, 132, 181–215] demonstrated that the word’s morphological structure may also be used in saccadic targeting. The study was conducted in a morphologically rich language, Uighur. The present study aimed at replicating their main findings in another morphologically rich language, Finnish. Similarly to Yan et al., it was found that the initial fixation landed closer to the word beginning for morphologically complex than for monomorphemic words. Word frequency, saccade launch site, and word length were also found to influence the initial landing position. It is concluded that in addition to low-level factors (word length and saccade launch site), also higher level factors related to the word’s morphological structure and frequency may be utilized in saccade programming during reading.

Cognitive or executive control is a critical mental ability, an important marker of mental illness, and among the most heritable of neurocognitive traits. Two candidate genes, catechol-O-methyltransferase (COMT) and DRD4, which both have a roles in the regulation of cortical dopamine, have been consistently associated with cognitive control. Here, we predicted that individuals with the COMT Met/Met allele would show improved response execution and inhibition as indexed by event-related potentials in a Go/NoGo task, while individuals with the DRD4 7-repeat allele would show impaired brain activity. We used independent component analysis (ICA) to separate brain source processes contributing to high-density EEG scalp signals recorded during the task. As expected, individuals with the DRD4 7-repeat polymorphism had reduced parietal P3 source and scalp responses to response (Go) compared to those without the 7-repeat. Contrary to our expectation, the COMT homozygous Met allele was associated with a smaller frontal P3 source and scalp response to response-inhibition (NoGo) stimuli, suggesting that while more dopamine in frontal cortical areas has advantages in some tasks, it may also compromise response inhibition function. An interaction effect emerged for P3 source responses to Go stimuli. These were reduced in those with both the 7-repeat DRD4 allele and either the COMT Val/Val or the Met/Met homozygous polymorphisms but not in those with the heterozygous Val/Met polymorphism. This epistatic interaction between DRD4 and COMT replicates findings that too little or too much dopamine impairs cognitive control. The anatomic and functional separated maximally independent cortical EEG sources proved more informative than scalp channel measures for genetic studies of brain function and thus better elucidate the complex mechanisms in psychiatric illness., Brain Topography, 31 (3), ISSN:0896-0267, ISSN:1573-6792

Theoretical models and preceding studies have described age-related alterations in neuronal activation of frontoparietal regions in a working memory (WM) load-dependent manner. However, to date, underlying neuronal mechanisms of these WM load-dependent activation changes in aging remain poorly understood. The aim of this study was to investigate these mechanisms in terms of effective connectivity by application of dynamic causal modeling with Bayesian Model Selection. Eighteen healthy younger (age: 20-32 years) and 32 older (60-75 years) participants performed an n-back task with 3 WM load levels during functional magnetic resonance imaging (fMRI). Behavioral and conventional fMRI results replicated age group by WM load interactions. Importantly, the analysis of effective connectivity derived from dynamic causal modeling, indicated an age- and performance-related reduction in WM load-dependent modulation of connectivity from dorsolateral prefrontal cortex to inferior parietal lobule. This finding provides evidence for the proposal that age-related WM decline manifests as deficient WM load-dependent modulation of neuronal top-down control and can integrate implications from theoretical models and previous studies of functional changes in the aging brain.

Defensive behaviors in animals and humans vary dynamically with increasing proximity of a threat and depending upon the behavioral repertoire at hand. The current study investigated physiological and behavioral adjustments and associated brain activation when participants were exposed to dynamically approaching threat that was either inevitable or could be avoided by motor action. When the approaching threat was inevitable, attentive freezing was observed as indicated by fear bradycardia, startle potentiation, and a dynamic increase in activation of the anterior insula and the periaqueductal grey. In preparation for active avoidance a switch in defensive behavior was observed characterized by startle inhibition and heart rate acceleration along with potentiated activation of the amygdala and the periaqueductal grey. Importantly, the modulation of defensive behavior according to threat imminence and the behavioral option at hand was associated with activity changes in the ventromedial prefrontal cortex. These findings improve our understanding of brain mechanisms guiding human behavior during approaching threat depending on available resources.

The present study employed a longitudinal person-centered approach to examine the profiles of reading motivation in a sample of 405 elementary school students who were tested in grades 3 and 4. Two dimensions of intrinsic reading motivation (involvement and curiosity) and two dimensions of extrinsic reading motivation (recognition and competition) were considered. Latent profile analyses revealed the same set of four profiles across third and fourth grades: high intrinsic (i.e., high on involvement and curiosity, low on recognition and competition), high involvement (i.e., high on involvement, low on the remaining dimensions), high quantity (high on all dimensions), and moderate quantity (low to moderate on all dimensions). Further results showed that 35% of the students changed their profile membership from third to fourth grade. We particularly observed an increased probability of students in the high-quantity, moderate-quantity, and high-involvement profiles to move to the high-intrinsic profile. Finally, the moderate-quantity profile proved to be significantly lower in reading amount than the other groups that did not differ significantly. Pertaining to reading comprehension, however, the two intrinsic profiles outperformed both the high- and moderate-quantity groups. The latter finding emphasizes the particular importance of intrinsic reading motivation.

Despite narcissists' use of social relationships for self-construction, no research to date has been devoted to understanding whether and to what extent narcissists desire social contact. To address this fundamental gap in the literature, the present study (N = 537) aimed to examine the relationships between facets of grandiose narcissism and individual differences in preference for solitude. It was hypothesized that agentic narcissism (i.e., narcissistic admiration) would be negatively related to the preference to be alone, whereas antagonistic narcissism (i.e., narcissistic rivalry) would be positively related to this preference. Structural Equation Modeling (SEM) confirmed this prediction, further revealing that these results were independent of self-esteem. These findings confirm the utility of a two-dimensional approach to narcissism and suggest that specific types of narcissistic individuals (i.e., narcissistic rivalry) enjoy spending time by themselves instead of with others.

Prenatal stress (PS) is an established risk factor in the etiology of mental disorders. Although mother-child interaction is the infant's first important training in dealing with stress, little is yet known about the impact of PS on mother-infant dyadic behavior. The current study aimed to elucidate the prospective influence of psychological and physiological stresses during pregnancy on mother-infant dyadic behavior. Mother-infant interactions were videotaped at 6-month postpartum and coded into three dyadic patterns: (1) both positive; (2) infant protesting-mother positive; and (3) infant protesting-mother negative, using the infant and caregiver engagement phases. Exposure to PS was assessed during pregnancy using psychological (i.e., psychopathological, perceived, and psychosocial PS; n = 164) and physiological stress measures (i.e., maternal cortisol; n = 134). Group comparisons showed that psychosocial PS was predictive of mother-infant behavior at 6-month postpartum, indicating that dyads of prenatally high-stressed mothers exhibited significantly more positive interaction patterns (i.e., infant positive-mother positive) as compared to the prenatally low-stressed group. Physiological PS was unrelated to mother-infant behavior. These results suggest that mild psychosocial PS may be advantageous for positive mother-infant dyadic behavior, which is in accordance with the stress-inoculation model that assumes a beneficial effect of PS.

Background: Post-traumatic stress disorder (PTSD) is one of the more commonly occurring mental disorders following potentially traumatizing events soldiers may encounter when deployed abroad. One of the first-line recommended treatment options is eye movement desensitization and reprocessing (EMDR). The number of studies assessing the effectiveness of EMDR in German soldiers under routine conditions is currently almost nil. Methods: A retrospective, quasi-experimental effectiveness study on EMDR in an inpatient setting is presented using a prepost design. The study compares symptom reduction in soldiers (N = 78) with a wait-list (N = 18). Effect sizes of EMDR were measured for PTSD, symptoms of depression, and general mental health. Results: Effect size for EMDR treatment of PTSD was d = 0.77; 95% confidence interval (CI): 0.51 to 1.36, for symptoms of depression d = 0.99; 95% CI: 0.31 to 1.36, and for general psychiatric symptoms d = 0.53; 95% CI: 0.17 to 1.21. The effects resulting from EMDR treatment were somewhat weaker than those reported in comparable studies in civilians. Conclusion: EMDR therapy is an effective treatment to reduce symptoms of PTSD and depression. However, in the military context it needs to be complemented by treatment options that specifically address further conditions perpetuating the disorders.

This study addressed the role of elementary school teachers' classroom management and mastery-oriented instructional practices as mediators of the effects of teacher motivation on student motivation. The sample comprised 110 teacher-class pairs (1731 students). The results from multilevel regression analyses revealed that teacher educational interest contributed to student reports of teachers' instructional practices. These practices, in turn, were significant predictors of students' subject interest and mastery goals at both the student and the class level. Finally, teacher educational interest showed significant and substantial indirect relations to student motivation that were mediated by teachers’ instructional practices.

Academic personal initiative (API) has rarely been studied with regard to literacy development. The purpose of this longitudinal study was therefore to examine the unique effects of API on the development of word comprehension as an indicator of word reading. To this end, the effects of previous word comprehension, intrinsic reading motivation, and basic cognitive ability (i.e., processing speed) were controlled for. A total of 1,515 German students participated in a longitudinal assessment starting in Grades 1 to 3, with a second point of measurement nine months later. Latent change score analyses revealed positive associations between API and gains in word comprehension, both in the total sample and at all grade levels. These relations were robust against the effects of previous word comprehension and intrinsic reading motivation. The findings suggest that children play an active role in their own reading development. (C) 2017 Elsevier Inc. All rights reserved.

Research based on the Eccles model of parent socialization demonstrated that parents are an important source of value and ability information for their children. Little is known, however, about the bidirectional effects between students' perceptions of their parents' beliefs and behaviors and the students' own domain-specific values. This study analyzed how students' perceptions of parents' beliefs and behaviors and students' mathematics values and mathematics-related career plans affect each other bidirectionally, and analyzed the role of students' gender as a moderator of these relations. Data from 475 students in 11th and 12th grade (girls: 50.3%; 31 classrooms; 12 schools), who participated in 2 waves of the study, were analyzed. Results of longitudinal structural equation models demonstrated that students' perceptions of their parents' mathematics value beliefs at Time 1 affected the students' own mathematics utility value at Time 2. Bidirectional effects were not shown in the full sample but were identified for boys. The paths within the tested model varied for boys and girls. For example, boys', not girls', mathematics intrinsic value predicted their reported conversations with their fathers about future occupational plans. Boys', not girls', perceived parents' mathematics value predicted the mathematics utility value. Findings are discussed in relation to their implications for parents and teachers, as well as in relation to gendered motivational processes. (PsycINFO Database Record

From the beginning of his work as a researcher, Heinz Heckhausen was interested in activities that are performed for their own sake and not only for some rewarding consequences-later addressed with the term "intrinsic motivation." One of his conceptual contributions to this area was the systematization of the bewildering heterogeneity of differentiations between various concepts of intrinsic and extrinsic motivation. In the conception, he himself preferred, intrinsic motivation could include incentives of actions outcome if the goal is thematically identical with the action. Doing so the per se goal directed achievement motivation could be understood as intrinsically motivated. This understanding of achievement motivation was productively utilized in educational psychology. His interest in intrinsic motivation stimulated research on activity specific incentives. One of these incentives is the total emergence with a smooth-running activity-an incentive Csikszentmihalyi had already described as "flow experience."

During scene perception our eyes generate complex sequences of fixations. Predictors of fixation locations are bottom-up factors like luminance contrast, top-down factors like viewing instruction, and systematic biases like the tendency to place fixations near the center of an image. However, comparatively little is known about the dynamics of scanpaths after experimental manipulation of specific fixation locations. Here we investigate the influence of initial fixation position on subsequent eye-movement behavior on an image. We presented 64 colored photographs to participants who started their scanpaths from one of two experimentally controlled positions in the right or left part of an image. Additionally, we computed the images' saliency maps and classified them as balanced images or images with high saliency values on either the left or right side of a picture. As a result of the starting point manipulation, we found long transients of mean fixation position and a tendency to overshoot to the image side opposite to the starting position. Possible mechanisms for the generation of this overshoot were investigated using numerical simulations of statistical and dynamical models. We conclude that inhibitory tagging is a viable mechanism for dynamical planning of scanpaths., 34 pages with 10 figures submitted to Vision Research.

Assessments of psychotherapeutic competencies play a crucial role in research and training. However, research on the reliability and validity of such assessments is sparse. This study aimed to provide an overview of the current evidence and to provide an average interrater reliability (IRR) of psychotherapeutic competence ratings. A systematic review was conducted, and 20 studies reported in 32 publications were collected. These 20 studies were included in a narrative synthesis, and 20 coefficients were entered into the meta-analysis. Most primary studies referred to cognitive-behavioral therapies and the treatment of depression, used the Cognitive Therapy Scale, based ratings on videos, and trained the raters. Our meta-analysis revealed a pooled ICC of 0.82, but at the same time severe heterogeneity. The evidence map highlighted a variety of variables related to competence assessments. Further aspects influencing the reliability of competence ratings and regarding the considerable heterogeneity are discussed in detail throughout the manuscript.

The SKT (Syndrom-Kurztest) is a short cognitive performance test assessing deficits of memory and attention in the sense of speed of information processing. The new standardization of the SKT (2015) aimed at improving its sensitivity for early cognitive decline due to dementia in subjects aged 60 or older. The goal of this article is to demonstrate how the neuropsychological test profile of the SKT can be used to provide valuable information for a differential diagnosis between MCI (mild cognitive impairment), dementia and depression. n = 549 patients attending a memory clinic (Nuremberg, Germany) were diagnosed according to ICD-10 and tested with the SKT. The SKT consists of nine subtests, three for the assessment of memory and six for measuring attention in the sense of speed of information processing. The result of the SKT test procedure is a total score, which indicates the severity of overall cognitive impairment. Besides the summary score, two subscores for memory and attention can be interpreted. Using the level of depression as a covariate, statistical comparisons of SKT test profiles between the three patient groups revealed that depressed patients showed more pronounced deficits than MCI patients in all six attention subtests. On the other hand, MCI patients displayed significantly greater mnestic impairment than the depressed group, which was indicated by significant differences in the memory subscore. MCI and dementia patients showed similar deficit patterns dominated by impairment of memory (delayed recall) with MCI patients demonstrating less overall impairment. In sum, the SKT neuropsychological test profiles provided indicators for a differential diagnosis between MCI and beginning dementia vs. depression.

Infants in the second year of life not only detect the visible goals or end-states of other people's action, but they also seem to be able to infer others’ underlying intentions. The present study used event-related potentials (ERPs) to investigate the biological basis of infants’ processing of others’ goal-directed actions, with special regard to the involvement of bottom-up perceptual and top-down conceptual processes. In an adaptation of the behavioral re-enactment procedure, 14-month-olds were first familiarized with either full demonstrations (FD), failed attempts (FA), or arbitrary (AA) object-directed actions. Next, ERPs were measured while all infants saw the same two pictures of the end-states of the full demonstration (complete end-state) and the failed attempt (incomplete end-state). In the time-windows related to perceptual processing (100–200 ms after stimulus onset) and to conceptual processing (300–700 ms), ERP negativity over frontal and central regions was higher for the complete than for the incomplete end-state in the FD and FA conditions. When comparing the FA and AA conditions, this pattern of results occurred only for the conceptual time domain. Moreover, beginning slow-wave activity (700–1000 ms) differed for the end-state pictures in the three conditions, suggesting differential encoding demands. Together, the electrophysiological data indicate that infants in the second year of life use bottom-up perceptual as well as top-down conceptual processing to give meaning to others' goal-directed actions.

Factorial experiments in research on memory, language, and in other areas are often analyzed using analysis of variance (ANOVA). However, for effects with more than one numerator degrees of freedom, e.g., for experimental factors with more than two levels, the ANOVA omnibus F-test is not informative about the source of a main effect or interaction. Because researchers typically have specific hypotheses about which condition means differ from each other, a priori contrasts (i.e., comparisons planned before the sample means are known) between specific conditions or combinations of conditions are the appropriate way to represent such hypotheses in the statistical model. Many researchers have pointed out that contrasts should be "tested instead of, rather than as a supplement to, the ordinary 'omnibus' F test" (Hays, 1973, p. 601). In this tutorial, we explain the mathematics underlying different kinds of contrasts (i.e., treatment, sum, repeated, polynomial, custom, nested, interaction contrasts), discuss their properties, and demonstrate how they are applied in the R System for Statistical Computing (R Core Team, 2018). In this context, we explain the generalized inverse which is needed to compute the coefficients for contrasts that test hypotheses that are not covered by the default set of contrasts. A detailed understanding of contrast coding is crucial for successful and correct specification in linear models (including linear mixed models). Contrasts defined a priori yield far more useful confirmatory tests of experimental hypotheses than standard omnibus F-tests. Reproducible code is available from https://osf.io/7ukf6/.

Listening comprehension in academic contexts is an important prerequisite for the acquisition of school-related skills. However, the concept of academic language is generally the subject of much debate, and there is no consensus yet on what constitutes academic listening comprehension. To date, it remains unclear whether listening comprehension of academic language may be regarded as a distinct construct. The present study investigates the distinction of academic and everyday listening comprehension in 459 ninth-grade students speaking German as a first language or as a second language. Empirical results provide preliminary evidence that academic listening forms a separate facet of listening comprehension. Contrary to theoretical assumptions, second language students were not particularly disadvantaged in terms of academic listening comprehension.

Background: Physicians and therapists are also consulted to give judgments on working ability. Ability to work cannot simply be derived from the patient’s symptom status but from the illness-related capacity impairments in relation to the work demands. A structured assessment of capacity impairments has been evaluated and applied internationally: the Mini-ICF-APP Social Functioning Scale. It is currently unclear whether a free-text clinical report (i.e., usual clinical practice: clinical exploration according to clinical standards, but without a standardized documentation form, instead a text is written) and a structured capacity assessment correspond to the overall work ability judgment, i.e., the decision whether a patient is “fit for work” or “unfit for work.” Objectives: This investigation assessed, for the first time, whether usual clinical judgment and the additional structured capacity rating support the work ability decision. Methods: A total of 100 medical reports from patients in a psychotherapy hospital were excerpted for psychopathological symptoms and capacity disorders using a checklist. Additionally, a structured assessment of capacity disorders was documented on the Mini-ICF-APP rating for all patients. Results: In the free-text clinical medical report, endurance, flexibility, and contacts to others were the things mainly reported as impaired. This was similar to the structured Mini-ICF-APP rating. However, other capacity impairments were also reported in the Mini-ICF-APP, i.e., adherence to rules and regulations, planning and structuring, assertiveness, and group integration. When the free-text clinical report and the structured Mini-ICF-APP rating were compared, there was a higher rate of stated impairments covering all capacity dimensions in the Mini-ICF-APP rating. Conclusions: The free-text report in the medical report shows the differences between patients who are fit for work and those who are not, and thus speak for the validity of work ability decisions. However, optimization is possible in terms of depth and differentiation of capacity impairment description by adhering to the standard set by the Mini-ICF-APP.

This study investigated predictors of mind wandering during reading and their effects on comprehension in a sample of secondary school children. One hundred and twenty-five eighth-graders read either an easy, moderately difficult, or difficult version of an expository text and subsequently answered a number of comprehension questions. Students were asked about their thoughts during reading, their propensity to mind wander in various life situations, as well as their interest in the topics of the text. Overall, the results were consistent with the general mind wandering literature: More difficult texts were associated with lower topic interest, more mind wandering during reading, and worse comprehension. Topic interest was negatively related to mind wandering during reading. Furthermore, the propensity to mind wander in daily life had both a positive effect and a negative effect on comprehension, the latter being mediated by mind wandering during reading. Based on these results, it is argued that mind wandering may benefit school children's reading comprehension if it is applied in appropriate situations and for activities that promote comprehension.

Objective: The purpose of this systematic review and meta-analysis was to examine the effects of exercise on depression and anxiety in people living with HIV (PLWH), and to evaluate, through subgroup analysis, the effects of exercise type, frequency, supervision by exercise professionals, study quality, and control group conditions on these outcomes. Method: A literature search was conducted through four electronic databases from inception to February 2019. Considered for inclusion were randomized controlled trials (RCTs) investigating exercise interventions and depression or anxiety as outcomes in people living with HIV (>= 18 years of age). Ten studies were included (n = 479 participants, 49.67% females at baseline), and the standardized mean difference (SMD) and heterogeneity were calculated using random-effect models. An additional pre-post meta-analysis was also conducted. Results: A large effect in favor of exercise when compared to controls was found for depression (SMD = -0.84, 95%CI = [-1.57, -0.11], p = 0.02) and anxiety (SMD = -1.23, 95%CI = [-2.42, 0.04], p = -0.04). Subgroup analyses for depression revealed large effects on depression for aerobic exercise only (SMD = -0.96, 95%CI = [-1.63, -0.30], p = 0.004), a frequency of >= 3 exercise sessions per week (SMD = -1.39, 95%CI = [-2.24, -0.54], p < 0.001), professionally supervised exercise (SMD = -1.40, 95%CI = [-2.46, -0.17], p = 0.03]), and high-quality studies (SMD = -1.31, 95%CI = [-2.46, -0.17], p = 0.02). Conclusion: Exercise seems to decrease depressive symptoms and anxiety in PLWH, but other larger and high-quality studies are needed to verify these effects.

Communication with young children is often multimodal in nature, involving, for example, language and actions. The simultaneous presentation of information from both domains may boost language learning by highlighting the connection between an object and a word, owing to temporal overlap in the presentation of multimodal input. However, the overlap is not merely temporal but can also covary in the extent to which particular actions co-occur with particular words and objects, e.g. carers typically produce a hopping action when talking about rabbits and a snapping action for crocodiles. The frequency with which actions and words co-occurs in the presence of the referents of these words may also impact young children’s word learning. We, therefore, examined the extent to which consistency in the co-occurrence of particular actions and words impacted children’s learning of novel word–object associations. Children (18 months, 30 months and 36–48 months) and adults were presented with two novel objects and heard their novel labels while different actions were performed on these objects, such that the particular actions and word–object pairings always co-occurred (Consistent group) or varied across trials (Inconsistent group). At test, participants saw both objects and heard one of the labels to examine whether participants recognized the target object upon hearing its label. Growth curve models revealed that 18-month-olds did not learn words for objects in either condition, and 30-month-old and 36- to 48-month-old children learned words for objects only in the Consistent condition, in contrast to adults who learned words for objects independent of the actions presented. Thus, consistency in the multimodal input influenced word learning in early childhood but not in adulthood. In terms of a dynamic systems account of word learning, our study shows how multimodal learning settings interact with the child’s perceptual abilities to shape the learning experience.

Successful communication often involves comprehension of both spoken language and observed actions with and without objects. Even very young infants can learn associations between actions and objects as well as between words and objects. However, in daily life, children are usually confronted with both kinds of input simultaneously. Choosing the critical information to attend to in such situations might help children structure the input, and thereby, allow for successful learning. In the current study, we therefore, investigated the developmental time course of children's and adults' word and action learning when given the opportunity to learn both word-object and action-object associations for the same object. All participants went through a learning phase and a test phase. In the learning phase, they were presented with two novel objects which were associated with a distinct novel name (e.g., "Look, a Tanu") and a distinct novel action (e.g., moving up and down while tilting sideways). In the test phase, participants were presented with both objects on screen in a baseline phase, then either heard one of the two labels or saw one of the two actions in a prime phase, and then saw the two objects again on screen in a recognition phase. Throughout the trial, participants' target looking was recorded to investigate whether participants looked at the target object upon hearing its label or seeing its action, and thus, would show learning of the word-object and action-object associations. Growth curve analyses revealed that 12-month-olds showed modest learning of action-object associations, 36-month-olds learned word-object associations, and adults learned word-object and action-object associations. These results highlight how children attend to the different information types from the two modalities through which communication is addressed to them. Over time, with increased exposure to systematic word-object mappings, children attend less to action-object mappings, with the latter potentially being mediated by word-object learning even in adulthood. Thus, choosing between different kinds of input that may be more relevant in their rich environment encompassing different modalities might help learning at different points in development.

The social context plays a decisive role in the formation of the academic self-concept (ASC) and has been widely studied as the big-fish-little-pond-effect (BFLPE). This effect describes that comparable talented students in high-achieving school settings have a lower ASC compared to equally talented students attending low-achieving settings. Past research has focused on students' domain-specific ASC, while little is known about the relation of achievement-related classroom compositions and the various facets of ASC. Additionally, BFLPE-research has been critiqued to build its theoretical frame on social comparison theory, without providing sufficient empirical support. To address this gap, we analyzed how the single student's social, criterial, absolute, and individual ASC relate to class-level achievement of 8th graders. Applying Multilevel Structural Equation Modeling (MLSEM) we found that all facets of ASC were significantly related to average-class achievement, while student's social ASC revealed the strongest associated. The results reveal explicitly that average-class achievement is strongly related to social comparison processes., Postprints der Universität Potsdam : Humanwissenschaftliche Reihe, 554

As intuitive eating (IE) is characterized by eating in response to internal cues of hunger and satiety and by monitoring the effect of food on the body, it has been hypothesized to lead to healthy food intake. Evidence concerning its link to food intake is scarce. This experimental study investigated the relationship between IE and food intake in middle-aged adults. Fifty-five participants aged 50–70 years completed the Intuitive Eating Scale-2 to measure IE. Usual consumption frequency of fruits, vegetables, snacks and sweets was assessed as a measure of healthy self-reported food intake. A taste test of apples, carrots, coated peanuts and chocolate was conducted as a measure of healthy and total laboratory food intake. Regression analyses were performed using Frequentist and Bayesian methods of inference. In line with our hypothesis, IE was associated with healthier self-reported food intake (medium effect size: f2 = 0.24). The data were 49.80 times more likely under H1 than under H0. Contrary to our hypotheses, IE was neither associated with healthy nor total laboratory food intake in classical regression analyses. The accompanying Bayes factors revealed inconclusive evidence. Data only allow drawing cautious conclusions about the different relationship between IE and the self-reported consumption frequency of the foods vs. the amount of these foods consumed in a single test situation. Future studies combining different measures of IE (e.g., behavioral paradigms) and self-reported (e.g., diet quality, portion sizes) and laboratory (e.g., repeated taste tests with pre-selected foods) food intake are warranted to further explore their relationship.

Background. In stress research, economic instruments for introducing acute stress responses are needed. In this study, we investigated whether the socially evaluated cold-pressor group test (SECPT-G) induces salivary alpha-amylase and/or cortisol responses in the general population and whether this is associated with anthropometric, experimental, and lifestyle factors. Methods. A sample of 91 participants from the general population was recruited. Salivary cortisol and alpha-amylase (sAA) levels were assessed prior to (t0), immediately after (t1), and ten minutes after the SECPT-G (t2). Results. A robust cortisol increase was found immediately after the SECPT-G, which further increased between t1 and t2. This was independent of most of the control variables. However, men showed a trend towards higher cortisol increases than women (p = .005). No sAA responses were found at all. However, sAA levels were dependent on measurement time point with highest levels between 9 pm and 9:30 pm. Participants who immersed their hands into the ice water for the maximally allowed time of three minutes showed higher sAA levels at all time points than participants who removed their hands from the water earlier. Conclusions. We conclude that the SECPT-G is a good means of an acute stress test when cortisol – but not necessarily sAA – responses are intended.

The present study sets out to address two fundamental questions in the reading of continuous texts: Whether semantic and phonological information from upcoming words can be accessed during natural reading. In the present study we investigated parafoveal processing during the reading of Korean sentences, manipulating semantic and phonological information from parafoveal preview words. In addition to the first evidence for a semantic preview effect in Korean, we found that Korean readers have stronger and more long-lasting phonological than semantic activation from parafoveal words in second-pass reading. The present study provides an example that human mind can flexibly adjust processing priority to different types of information based on the linguistic environment.

Rooted in Eccles and colleagues' expectancy-value theory, this study aimed to examine how expectancies and different facets of task value combine to diverse profiles of motivational beliefs, how such complex profiles develop across a school year, and how they relate to gender and career plans. Despite abundant research on the association between gender and motivational beliefs, there is a paucity of knowledge regarding the gendered development of student motivational belief profiles in specific domains. Using latent-transition analysis in a sample of N = 751 ninth to tenth graders (55.9% girls), we investigated girls' and boys' development of motivational belief profiles (profile paths) in mathematics across a school year. We further analyzed the association between these profile paths and math-related career plans. The results revealed four motivational belief profiles: high motivation (intrinsic and attainment oriented), balanced above average motivation, average motivation (attainment and cost oriented), and low motivation (cost oriented). Girls were less likely than expected by chance to remain in the high motivation profile, while the opposite was true for boys. The math-relatedness of students' career plans was significantly higher in the "stable high motivation" profile path than in all other stable profile paths.

This article introduces a new corpus of eye movements in silent reading-the Russian Sentence Corpus (RSC). Russian uses the Cyrillic script, which has not yet been investigated in cross-linguistic eye movement research. As in every language studied so far, we confirmed the expected effects of low-level parameters, such as word length, frequency, and predictability, on the eye movements of skilled Russian readers. These findings allow us to add Slavic languages using Cyrillic script (exemplified by Russian) to the growing number of languages with different orthographies, ranging from the Roman-based European languages to logographic Asian ones, whose basic eye movement benchmarks conform to the universal comparative science of reading (Share, 2008). We additionally report basic descriptive corpus statistics and three exploratory investigations of the effects of Russian morphology on the basic eye movement measures, which illustrate the kinds of questions that researchers can answer using the RSC. The annotated corpus is freely available from its project page at the Open Science Framework: https://osf.io/x5q2r/ .

This research was designed to adapt and investigate the psychometric properties of the Short Dark Triad measure (Jones and Paulhus Assessment, 21(1), 28-41, 2014) in a German sample within four studies (total N = 1463); the measure evaluates three personality dimensions: narcissism, psychopathy, and Machiavellianism. The structure of the instrument was analysed by Confirmatory Factor Analyses procedure. It indicated that the three-factor structure had the best fit to the data. Next, the Short Dark Triad measure was evaluated in terms of construct, convergent and discriminant validity, internal consistency (≥ .72), and test-retest reliability during a 4-week period (≥ .73). Concurrent validity of the SD3 was supported by relating its subscales to measures of the Big Five concept, aggression, and self-esteem. We concluded that the Short Dark Triad instrument presented high cross-language replicability. The use of this short inventory in the investigation of the Dark Triad personality model in the German language context is suggested.

Scene viewing is used to study attentional selection in complex but still controlled environments. One of the main observations on eye movements during scene viewing is the inhomogeneous distribution of fixation locations: While some parts of an image are fixated by almost all observers and are inspected repeatedly by the same observer, other image parts remain unfixated by observers even after long exploration intervals. Here, we apply spatial point process methods to investigate the relationship between pairs of fixations. More precisely, we use the pair correlation function, a powerful statistical tool, to evaluate dependencies between fixation locations along individual scanpaths. We demonstrate that aggregation of fixation locations within 4 degrees is stronger than expected from chance. Furthermore, the pair correlation function reveals stronger aggregation of fixations when the same image is presented a second time. We use simulations of a dynamical model to show that a narrower spatial attentional span may explain differences in pair correlations between the first and the second inspection of the same image.

Previous research on dispositional optimism has predominantly concentrated on the selection effect of dispositional optimism on predicting work outcomes. Recent research, however, has started to examine the socialization effect of life experiences on fostering dispositional optimism development. Extrapolating primarily from the TESSERA framework of personality development (Wrzus & Roberts, 2017) and the literature on dispositional optimism, the current study represents a first attempt to reconcile the 2 seemingly contrasting perspectives. We proposed and examined change-related reciprocal relationships between dispositional optimism and work experience variables including income, job insecurity, coworker support, and supervisor support. Latent change score modeling of data from a five-wave longitudinal study demonstrated that dispositional optimism resulted in decreases in job insecurity, and the decreased job insecurity in turn promoted further increases in dispositional optimism later on. Furthermore, income gave rise to increases in dispositional optimism at a later point in time, but not vice versa. No significant relationships were observed between dispositional optimism and coworker and supervisor support. The findings provide a cautionary note to the majority of previous research based on cross-sectional and lagged designs that assumes causal effects of dispositional optimism on work outcomes. They also showcase the importance of examining personality change in organizational research and enrich our understanding of a more nuanced dynamic interplay between the optimistic employee and the work environment.

Objective This prospective study explored bidirectional associations between attachment quality towards mother, father, and peers and disordered eating among a large population-based sample of boys and girls in the transition from preadolescence to adolescence. Specifically, we examined whether insecure attachment relationships emerged as a risk factor for or as an outcome of disordered eating. Method A population-based sample of 904 adolescent girls and boys was assessed four times, at baseline (T1; M-age = 10.8 years) and at 2-, 4-, and 6-year follow-up (T2, T3, and T4). Prospective data were analyzed using cross-lagged panel models for each attachment figure (i.e., mother, father, peers) in a multigroup design to compare genders. Results Better attachment to the mother led to less pronounced disturbed eating in girls across the entire age range and in boys across two time periods. In girls, more pronounced disordered eating at T3 predicted worse attachment to the mother at T4 and better attachment to the father at T1 predicted less disturbed eating at T2. In boys, disordered eating at T1 predicted better attachment to the father at T2. Concerning peer attachment, better attachment at T1 predicted disordered eating at T2, in boys only. No other significant cross-lagged effects emerged. Discussion These findings highlight the differential and gender-specific contribution of attachment figures to the development of disordered eating in adolescence. Programs aimed at improving communication and trust in the relationship with parents might be promising in the prevention of disordered eating and the subsequent deterioration of parent-child attachment relationships.

Recent research on proactive work behaviours (PWBs) pointed out that these behaviours can have negative consequences for the proactive individual. We add to this perspective by showing that PWBs may be a source of strain at work and result in elevated time pressure. Challenging the view of time pressure as a challenge stressor, we hypothesize that over the course of work weeks, time pressure will result in less (rather than more) PWB. We investigate these reciprocal effects as within-person, week-level fluctuations of time pressure and PWB based on experience sampling data (N = 52 participants, k = 274 observations). Over the course of three consecutive work weeks, results show a positive lagged effect of PWB in the first week on experiencing time pressure in the second week; in turn, time pressure in the second week had a negative lagged effect on PWB in the third week. Results further suggest that PWB is lowest in work weeks of low time pressure when following a week of high time pressure, indicating a conservation of resources interpretation of the results.

This two-wave longitudinal study examined risky sexual scripts and sexual behavior regarding consensual sexual interactions, sexual self-esteem, initiation assertiveness, and religiosity as predictors of sexual aggression perpetration in a cross-cultural comparison of college students in Chile and Turkey. As predicted, risky sexual scripts were linked to higher odds of perpetration through more risky sexual behavior cross-sectionally in both the Chilean and the Turkish sample and indirectly predicted perpetration 12 months later. High sexual self-esteem increased the likelihood of perpetration via higher initiation assertiveness in the Turkish sample only. High religiosity reduced the odds of perpetration through less risky sexual scripts and less risky sexual behavior in both samples. In addition, high religiosity increased the probability of perpetration through lower sexual self-esteem in the Turkish sample. Implications of these findings and the role of cultural factors contributing to the differential functioning of religiosity and sexual self-esteem are discussed.
