Background: Over the past few decades early self-regulation has been identified as foundational to positive learning and wellbeing trajectories. As a consequence, a wide range of approaches have been developed to capture children's developmental progress in self-regulation. Little is known, however, about whether and which of these are reliable indicators of future ability and risk for young children. Objective: This study examined measures from prominent approaches to self-regulation assessment (i.e., task-based, observation, adult-report) to determine: their structure; how these predict future academic school readiness in 3-5-year-old children, individually and if combined; and whether thresholds could be ascertained to reliably discriminate those children at risk of poor academic outcomes. Methods: Longitudinal analyses were conducted on start-of-year self-regulation data from 217 children in the final year of pre-school, using three prominent approaches to self-regulation assessment, and their end-of-year school readiness data. Data were subjected to path analysis, structural equation modelling and receiver operating characteristic curve analyses. Results: Start-of-year cognitive self-regulation indices--but not behavioral or emotional self-regulation indices--from each approach reliably predicted school readiness 7 months later, just prior to commencing school. Only when combined into a composite score was a threshold with sufficient sensitivity and specificity for predicting school readiness risk established; yet this provided better prediction of true-negative than true-positive cases. Conclusions: Taken together, these results suggest the importance of cognitive self-regulation in particular for school readiness, as measured here, although self-regulation is just one of the contributing factors to school readiness risk.

This paper presents a selective review of the literature addressing the influence of young children's conversational environments and interactions on their psychological understanding of persons. Our dual purposes are to reveal some consensus on the current state of knowledge and to foster a programmatic approach to future research. The initial sections clarify what is meant by conversation and describe the nature of theory-of-mind development. We adopt the term socio-cognitive development to convey the fact that children's theory-of-mind understanding becomes more elaborate and flexible throughout childhood, and we discuss issues of measurement. The following sections deal directly with the influence of conversational environments and interactions on children's socio-cognitive understanding. We present findings that suggest that conversational interactions are of fundamental importance for the development of children's socio-cognitive understanding, and we examine the particular aspects of the former that have been shown to be the most effective in promoting the latter. We discuss the relationship between children's conversational references to thoughts and feelings and experimental assessments of their socio-cognitive understanding, and we offer a detailed list of considerations for future research. In the remaining sections, we highlight the important roles of (i) young children's expanding linguistic competence and (ii) their relationships, and we discuss implications for individual differences in children's developing social competence.

Introduction: Substantial research indicates that high quality early childhood education and care (ECEC) confers a wide range of benefits for children, yet quality in ECEC remains inconsistent. Given the variability in training and qualifications, one strategy for improving ECEC quality is in-service professional development (PD)., Methods: The current study evaluated an evidence-based in-service PD programme, Leadership for Learning, via a cluster randomised controlled trial involving 83 ECEC services and 1,346 children in their final year of pre-school., Results: Results indicated significant improvements in teaching quality across treatment centres and child development outcomes in language, numeracy and social-emotional development., Discussion: This study provides strong support for making evidence-informed PD routinely available for ECEC practitioners., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Siraj, Melhuish, Howard, Neilsen-Hewett, Kingston, De Rosnay, Huang, Gardiner and Luu.)

Despite a tendency to study executive function (EF) and self-regulation (SR) separately, parallel lines of research suggest considerable overlap between the two abilities. Specifically, both show similar developmental trajectories (i.e., develop rapidly in the early years), predict a broad range of overlapping outcomes across the lifespan (e.g., academic success, mental and physical health, and social competence), and have overlapping neural substrates (e.g., prefrontal cortex). While theoretical frameworks diverge in how they reconcile EF and SR - ranging from treating the two as functionally synonymous, to viewing them as related yet distinct abilities - there is no consensus and limited empirical evidence on the nature of their relationship and how this extends developmentally. The current study examined bi-directional longitudinal associations between early EF and SR, and their longitudinal associations with subsequent early academic skills, in a sample of 199 3- to 5-year-old pre-school children. The adopted measures permitted EF and SR to be modelled as composite indices for these analyses, thereby decreasing task-specific components of these associations. Early academic skills were captured by a standardized direct assessment. Bi-directional associations between EF and SR were found, with both accounting for unique variance in early academic skills 7 and 19months later. The current results provide important evidence to distinguish between EF and SR abilities, yet also for their reciprocal influence in situ and across early development., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Howard, Vasseleu, Neilsen-Hewett, de Rosnay, Chan, Johnstone, Mavilidi, Paas and Melhuish.)

Aim: This study examined the prevalence and risk factors of fine motor delay in Australian pre-school children from low-income communities., Methods: Children from the Early Start Baseline Study completed the Ages and Stages Questionnaire (3rd edn.). Age, sex, executive function and family characteristics were assessed and associations with fine motor skills analysed., Results: Data were available for 700 children (M age 54.0 ± 8.6 months, 53.1% boys) of which 77.4% were typically developing, 12.1% at risk and 10.4% delayed for fine motor skill. Children had higher odds of being delayed if they were male (odds ratio (OR) 3.30, 95% confidence interval (CI) 2.22-4.90) or indigenous (OR 3.31, 95% CI 2.12-5.16) and had lower self-regulatory (OR 2.17, 95% CI 1.31-3.58). Higher vocabulary (OR 0.92, 95% CI 0.89-0.94), higher family income (OR 0.22, 95% CI 0.05-0.90) and family education (OR 0.25, 95% CI 0.08-0.74) were associated with lower odds of delay., Conclusion: Almost one in four children from vulnerable communities experience fine motor difficulties, highlighting the importance of early screening and targeting key child and environmental risk factors., (© 2020 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).)

Research has focused on the role of theory of mind (ToM) for positive social behaviour, while the association between ToM and negative social behaviours is less well understood. This longitudinal study compares two mediation models examining the role of ToM and peer-rated social preference at ages 5 and 6 for bullying at age 7. Participants were 114 children (58 boys, M age  = 67 months) at entry to primary school (T1). At Time 2 (T2), 106 children and, at Time 3 (T3), 96 children remained. Teacher-rated externalizing problems and children's language ability were controlled at T1. Poor ToM was found to indirectly predict later bullying via poor social preference, while for boys only, greater earlier ToM directly predicted greater bullying 2 years later. These results suggest that there are different pathways to bullying via ToM and social preference, which has implications for interventions to prevent the development of bullying behaviour., (© 2020 The British Psychological Society.)

Research into moral identity has provided much support for its role in mature moral functioning, yet the developmental course of this construct remains poorly understood. In this review, we examine the dominant developmental model of moral identity, which emphasizes its key relation with the moral self of early childhood. In reviewing evidence for the model, the assumption of correspondence between the moral self of early childhood and moral identity in adolescence is challenged, in terms of both the moral component and the sense-of-self entailed in both constructs. We argue that progress in mapping the developmental course of moral identity stands to be informed by a focus on middle childhood, which to date has been largely neglected in this literature, despite evidence implicating this period from related fields of inquiry. A number of specific directions for future developmental research into moral identity are outlined based on this perspective. Statement of contribution What is already known on this subject? Moral identity is central to adolescent moral functioning. Early childhood 'moral self' becomes adolescent moral identity. What does this study add? The current dominant developmental model is examined. The model is found to have questionable validity. Middle childhood may be of unique importance to the emergence of moral identity., (© 2018 The British Psychological Society.)

Background: The new Australian 24-Hour Movement Guidelines for the Early Years recommend that, for preschoolers, a healthy 24-h includes: i) ≥180 min of physical activity, including ≥60 min of energetic play, ii) ≤1 h of sedentary screen time, and iii) 10-13 h of good quality sleep. Using an Australian sample, this study reports the proportion of preschool children meeting these guidelines and investigates associations with social-cognitive development., Methods: Data from 248 preschool children (mean age = 4.2 ± 0.6 years, 57% boys) participating in the PATH-ABC study were analyzed. Children completed direct assessments of physical activity (accelerometry) and social cognition (the Test of Emotional Comprehension (TEC) and Theory of Mind (ToM)). Parents reported on children's screen time and sleep. Children were categorised as meeting/not meeting: i) individual guidelines, ii) combinations of two guidelines, or iii) all three guidelines. Associations were examined using linear regression adjusting for child age, sex, vocabulary, area level socio-economic status and childcare level clustering., Results: High proportions of children met the physical activity (93.1%) and sleep (88.7%) guidelines, whereas fewer met the screen time guideline (17.3%). Overall, 14.9% of children met all three guidelines. Children meeting the sleep guideline performed better on TEC than those who did not (mean difference [MD] = 1.41; 95% confidence interval (CI) = 0.36, 2.47). Children meeting the sleep and physical activity or sleep and screen time guidelines also performed better on TEC (MD = 1.36; 95% CI = 0.31, 2.41) and ToM (MD = 0.25; 95% CI = -0.002, 0.50; p = 0.05), respectively, than those who did not. Meeting all three guidelines was associated with better ToM performance (MD = 0.28; 95% CI = -0.002, 0.48, p = 0.05), while meeting a larger number of guidelines was associated with better TEC (3 or 2 vs. 1/none, p < 0.02) and ToM performance (3 vs. 2, p = 0.03)., Conclusions: Strategies to promote adherence to the 24-Hour Movement Behaviour Guidelines for the Early Years among preschool children are warranted. Supporting preschool children to meet all guidelines or more guidelines, particularly the sleep and screen time guidelines, may be beneficial for their social-cognitive development.

Background: Prevalence estimates internationally suggest that many preschool-aged children (3-5 years) are insufficiently physically active and engage in high levels of screen-based entertainment. Early childhood is the developmental period for which we know the least about the effects of physical activity on development and health. Likewise, rapid technological advancements in mobile electronic media have made screen-based forms of entertainment for young children ubiquitous, and research demonstrating the impacts on cognition, psychosocial well-being, and health has lagged behind the rate of adoption of these technologies. The purpose of the Preschool Activity, Technology, Health, Adiposity, Behaviour and Cognition (PATH-ABC) study is to investigate if physical activity and screen-based entertainment are independently associated with cognitive and psychosocial development, and health outcomes in young children, and if so, how much and which types of these behaviours might be most influential., Methods: The PATH-ABC study is a prospective cohort, aiming to recruit 430 3-5 year-old children. Children are recruited through and complete initial assessments at their Early Childhood Education and Care (ECEC) centre, and then 12-months later at their centre or school. Direct assessments are made of children's habitual physical activity using accelerometry, cognitive (executive function) and language development (expressive vocabulary), psychosocial development (emotional understanding, Theory of Mind, empathy, and heart rate variability), adiposity (body mass index and waist circumference), and cardiovascular health (blood pressure and retinal micro- vasculature). Educators report on children's psychological strengths and difficulties and self-regulation. Parents report on children's habitual use of electronic media and other child, parent and household characteristics., Discussion: The PATH-ABC study aims to provide evidence to enhance understanding of how much and which types of physical activity and screen-based media influence development and health in preschool-aged children. This information would benefit parents, educators, health professionals and governments seeking to develop strategies and policies to give young children the best start in life by promoting healthy levels of physical activity and electronic media use.

Although key differences have been found in boys' and girls' prosocial behavior toward peers, few studies have systematically examined gender differences in how intrinsic perspective-taking abilities-theory of mind (ToM) and emotion understanding (EU)-and the extrinsic peer environment relate to prosocial behavior. In this prospective longitudinal study, we studied gender differences in the relations between children's observed prosocial behavior and their ToM, EU, and social preference ratings in 114 children (58 boys and 56 girls). We used conventional ToM and EU tasks at 5 and 7years of age. Observed prosocial behavior in triadic peer interactions was assessed at both time points. Controlling for gender, age, verbal ability, and earlier prosocial behavior, ToM at 5years was found to predict prosocial behavior at 7years. Results also revealed gender-differentiated associations at 7years, whereby only girls' prosocial behavior was positively associated with EU. Results are discussed in terms of gender-differentiated patterns of socialization., (Copyright © 2016 Elsevier Inc. All rights reserved.)

Background: A substantial research base documents the benefits of attendance at high-quality early childhood education and care (ECEC) for positive behavioural and learning outcomes. Research has also found that the quality of many young children's experiences and opportunities in ECEC depends on the skills, dispositions and understandings of the early childhood adult educators. Increasingly, research has shown that the quality of children's interactions with educators and their peers, more than any other programme feature, influence what children learn and how they feel about learning. Hence, we sought to investigate the extent to which evidence-based professional development (PD) - focussed on promoting sustained shared thinking through quality interactions - could improve the quality of ECEC and, as a consequence, child outcomes., Methods/design: The Fostering Effective Early Learning (FEEL) study is a cluster randomised controlled trial for evaluating the benefits of a professional development (PD) programme for early childhood educators, compared with no extra PD. Ninety long-day care and preschool centres in New South Wales, Australia, will be selected to ensure representation across National Quality Standards (NQS) ratings, location, centre type and socioeconomic areas. Participating centres will be randomly allocated to one of two groups, stratified by centre type and NQS rating: (1) an intervention group (45 centres) receiving a PD intervention or (2) a control group (45 centres) that continues engaging in typical classroom practice. Randomisation to these groups will occur after the collection of baseline environmental quality ratings. Primary outcomes, at the child level, will be two measures of language development: verbal comprehension and expressive vocabulary. Secondary outcomes at the child level will be measures of early numeracy, social development and self-regulation. Secondary outcomes at the ECEC room level will be measures of environmental quality derived from full-day observations. In all cases, data collectors will be blinded to group allocation., Discussion: This is the first randomised controlled trial of a new approach to PD, which is focussed on activities previously found to be influential in children's early language, numeracy, social and self-regulatory development. Results should inform practitioners, policy-makers and families of the value of specific professional development for early childhood educators., Trial Registration: Australian New Zealand Clinical Trials Registry (ACTRN) identifier ACTRN12616000536460 . Registered on 27 April 2016. This trial was retrospectively registered, given the first participant (centre) had been enrolled at the time of registration.

Anticipating future interactions is characteristic of our everyday social experiences, yet has received limited empirical attention. Little is known about how children with autism spectrum disorder, known for their limitations in social interactive skills, engage in social anticipation. We asked children with autism spectrum disorder and their typically developing counterparts to consider an interaction with another person in the near future. Our results suggest that children with autism spectrum disorder and typically developing children performed similarly when anticipating the age, gender, and possible questions of another person, but children with autism spectrum disorder struggled more to anticipate what they would say in response to an anticipated interaction. Furthermore, such responses were robustly associated with imaginative capacities in typically developing children but not children with autism spectrum disorder. Our findings suggest that the cognitive mechanisms of social anticipation may differ between these groups., (© The Author(s) 2014.)

Two descriptive studies set out a new approach for exploring the dynamic features of children's affective responses (sadness and interest-worry) to another's distress. In two samples (N(study1) = 75; N(study2) = 114), Kindergarten children were shown a video-vignette depicting another child in distress and the temporal pattern of spontaneous expressions were examined across the unfolding vignette. Results showed, in both study 1 and 2, that sadness and interest-worry had distinct patterns of elicitation across the events of the vignette narrative and there was little co-occurrence of these affects within a given child. Temporal heart rate changes (study 2) were closely aligned to the events of the vignette and, furthermore, affective responses corresponded to distinctive physiological response profiles. The implications of distinct temporal patterns of elicitation for the meaning of sadness and interest-worry are discussed within the framework of emotion regulation and empathy.

Fink, Begeer, Peterson, Slaughter, and de Rosnay (2014) conducted a prospective longitudinal study showing that theory-of-mind (ToM) development at school entry (mean age 5.61 years) significantly predicted friendlessness both concurrently and 2 years later. Friendlessness (defined as lacking any friendship that is mutually reciprocated) is conceptually and empirically distinct from group popularity and independently predicts adverse mental health outcomes throughout life. Here, we respond to the thoughtful commentaries by Wellman (Brit. J. Dev. Psychol, 2015; 33, 24-26), Mizokawa and Koyasu (Brit. J. Dev. Psychol, 2015; 33, 21-23), and Lerner and Lillard (Brit. J. Dev. Psychol, 2015; 33, 18-20) with a focus on three key issues, namely (a) the definition and measurement of friendship, (b) the measurement of advanced ToM development beyond the preschool years, and (c) the exciting future potential for ToM-based training and intervention studies to combat chronic friendlessness., (© 2015 The British Psychological Society.)

Chronic friendlessness in childhood predicts adverse mental health outcomes throughout life, yet its earliest roots are poorly understood. In theory, developing a theory of mind (ToM) should help children gain mutual friends and one preschool study (Peterson & Siegal, 2002. Br J Dev Psychol, 20, 205) suggested a cross-sectional connection. We therefore used a 2-year prospective longitudinal design to explore ToM as a predictor of mutual friendship in 114 children from age 5 to 7 years after controlling potential confounds including language ability and group popularity. Confirming friendship's distinctiveness from group sociometric status, numerous group-rejected children (53%) had a mutual friend whereas 23% of those highest in group status did not. Five-year-olds with a mutual friend significantly outperformed their friendless peers on a comprehensive ToM battery (basic and advanced false belief). Longitudinally, chronically friendless 7-year-olds (no friends at either testing time) stood out for their exceptionally poor Time 1 ToM understanding even after controlling for group popularity, age, and language skill. Extending previous evidence of ToM's predictive links with later social and cognitive outcomes, these results for mutual friendship suggest possible interventions to help reduce the lifelong mental health costs of chronic friendlessness., (© 2014 The British Psychological Society.)

Links between young children's everyday use of mindful conversational skills and their success on laboratory tests of theory of mind understanding (ToM) were evaluated. Using published scales, teachers rated the conversational behavior and shyness of 129 children aged 60 to 101 months (M = 78·8 months) who were in their first years of primary school. The children also took batteries of first- and second-order false-belief tests along with tests of emotion understanding and general language ability. Correlational and regression analyses showed that performance on false-belief tests of ToM significantly predicted children's competence at reading others' minds in their everyday conversational interactions. Furthermore, these links transcended individual differences in language ability, shy personality, emotion understanding, and age. These findings augment and extend a growing body of evidence linking performance on laboratory ToM tests to socially competent real-world behavior.

The empirical literature has presented inconsistent evidence for deficits in the recognition of basic emotion expressions in children with autism spectrum disorders (ASD), which may be due to the focus on research with relatively small sample sizes. Additionally, it is proposed that although children with ASD may correctly identify emotion expression they rely on more deliberate, more time-consuming strategies in order to accurately recognize emotion expressions when compared to typically developing children. In the current study, we examine both emotion recognition accuracy and response time in a large sample of children, and explore the moderating influence of verbal ability on these findings. The sample consisted of 86 children with ASD (M age = 10.65) and 114 typically developing children (M age = 10.32) between 7 and 13 years of age. All children completed a pre-test (emotion word-word matching), and test phase consisting of basic emotion recognition, whereby they were required to match a target emotion expression to the correct emotion word; accuracy and response time were recorded. Verbal IQ was controlled for in the analyses. We found no evidence of a systematic deficit in emotion recognition accuracy or response time for children with ASD, controlling for verbal ability. However, when controlling for children's accuracy in word-word matching, children with ASD had significantly lower emotion recognition accuracy when compared to typically developing children. The findings suggest that the social impairments observed in children with ASD are not the result of marked deficits in basic emotion recognition accuracy or longer response times. However, children with ASD may be relying on other perceptual skills (such as advanced word-word matching) to complete emotion recognition tasks at a similar level as typically developing children.

Children's affective experiences and cognitive abilities have an impact on emotion understanding. However, their relative contribution, as well as the possibility of an interaction between them, has rarely been examined. The aim of the present study was to evaluate the influence of severe abuse and learning difficulties on simple and complex components of emotion understanding in late childhood and early adolescence. A total of 28 older children and young adolescents were selected for the study. Half of the participants had suffered from severe abuse, and half of these abused children additionally had learning disabilities. The remaining half of the sample had no history of abuse but were matched with the abused children on learning difficulties, age and gender. The participants' emotion understanding was assessed with the Test of Emotion Comprehension (TEC). Results showed that (a) learning difficulties but not abuse had an impact on emotion understanding, (b) there was no interaction effect of abuse and learning difficulties on emotion understanding, and (b) the observed effects of learning difficulties were most apparent for the understanding of relatively complex components of emotion and not for simple components. The results are discussed in terms of their theoretical and practical implications.

The understanding of emotions based on counterfactual reasoning was studied in children with high-functioning autism spectrum disorders (n = 71) and in typically developing children (n = 71), aged 6-12 years. Children were presented with eight stories about two protagonists who experienced the same positive or negative outcome, either due to their own action or by default. Relative to the comparison group, children with high-functioning autism spectrum disorder were poor at explaining emotions based on downward counterfactual reasoning (i.e. contentment and relief). There were no group differences in upward counterfactual reasoning (i.e. disappointment and regret). In the comparison group, second-order false-belief reasoning was related to children's understanding of second-order counterfactual emotions (i.e. regret and relief), while children in the high-functioning autism spectrum disorder group relied more on their general intellectual skills. Results are discussed in terms of the different functions of counterfactual reasoning about emotion and the cognitive style of children with high-functioning autism spectrum disorder.

The present study evaluated the possibility of collecting cardiac vagal tone data using a photoplethysmograph, and its stability and continuity in a longitudinal sample of early-school aged children. A method for the optical (i.e., blood volume pulse) estimation of heart rate was established in a pilot study. Then the longitudinal stability and continuity in photoplethysmograph-derived vagal tone was assessed in 114 children (56 girls) at three sessions between 5 and 7 years of age. Results indicate that this method possesses substantial measurement reliability and individual stability, as children report low intra-individual variation over time. Children also report a mean decrease in vagal tone from 5 to 7 years of age, consistent with increased attentional capacity. Overall, this suggests blood volume pulse estimation of vagal tone is both accurate and appropriate for naturalistic developmental research., (© 2012 Wiley Periodicals, Inc.)

Relations among indices of maternal mind-mindedness (appropriate and nonattuned mind-related comments) and children's: (a) internal state vocabulary and perspectival symbolic play at 26 months (N = 206), and (b) theory of mind (ToM) at 51 months (n = 161) were investigated. Appropriate comments were positively associated with ToM, but were unrelated to internal state language and perspectival symbolic play. Nonattuned comments were negatively correlated with internal state language and perspectival symbolic play, but were unrelated to ToM. Path analyses indicated that the best fit model assumed: (a) indirect links between nonattuned comments and ToM via children's perspectival symbolic play, (b) a direct link between appropriate comments and ToM, and (c) an indirect link between appropriate comments and ToM via children's concurrent receptive verbal ability., (© 2013 The Authors.

In a socially diverse sample of 206 infant-mother pairs, we investigated predictors of infants' attachment security at 15 months, with a particular emphasis on mothers' tendency to comment appropriately or in a non-attuned manner on their 8-month-olds' internal states (so-called mind-mindedness). Multinomial logistic regression analyses showed that higher scores for appropriate mind-related comments and lower scores for non-attuned mind-related comments distinguished secure-group mothers from their counterparts in the insecure-avoidant, insecure-resistant, and insecure-disorganized groups. Higher scores for appropriate mind-related comments and lower scores for non-attuned mind-related comments also independently predicted dichotomous organized/disorganized attachment. General maternal sensitivity predicted neither attachment security nor organization, although sensitivity was found to relate to dichotomous secure/insecure attachment specifically in the context of low socioeconomic status. The findings highlight how appropriate and non-attuned mind-related comments make independent contributions to attachment and suggest that mind-mindedness is best characterized as a multidimensional construct., (Copyright © International Society on Infant Studies (ISIS).)

Responses to an unfamiliar adult were examined in infants of mothers with social phobia (N= 79) and infants of nonanxious comparison mothers (N= 77) at 10 and 14 months in a social referencing paradigm. On each occasion, a female stranger first interacted with the mother and then approached and interacted with the infant. Over time, infants of mothers with social phobia showed increasing avoidance of the stranger, particularly when they were behaviorally inhibited. In boys, maternal social phobia was associated with increasing fearful responses. Infant avoidance was predicted by expressed maternal anxiety and low levels of encouragement to interact with the stranger. The findings are discussed in relation to theories concerning the intergenerational transmission of social anxiety.

In this experiment we investigated the impact of indirect expressions of maternal social anxiety on infant interactions with a stranger. A social referencing paradigm was used in which infants first observed their mothers interacting with a stranger and then interacted with the stranger themselves. Mothers made no direct communicative gestures to the infant concerning the stranger throughout the procedure. There were two experimental conditions experienced by all mother-infant pairs (N = 24; 12 boys)-non-anxious and socially anxious-and there were two male strangers. Infants were between 12 and 14 months (M = 12.8, SD = .76). Order of condition and stranger presentation were counter-balanced. Before testing, mothers, none of whom were significantly socially anxious, were trained to behave in a non-anxious and a socially anxious manner on the basis of clinical and empirical descriptions of social phobia. The results showed that, compared to their responses following their mothers interacting normally with a stranger, following a socially anxious mother-stranger interaction, infants were significantly more fearful and avoidant with the stranger. Infant-stranger avoidance was further modified by infant temperament; high fear infants were more avoidant in the socially anxious condition than low-fear infants. We discuss these findings in light of the possible mechanisms underpinning infant affective and behavioral responsiveness.

Over the last two decades, it has been established that children's emotion understanding changes as they develop. Recent studies have also begun to address individual differences in children's emotion understanding. The first goal of this study was to examine the development of these individual differences across a wide age range with a test assessing nine different components of emotion understanding. The second goal was to examine the relation between language ability and individual differences in emotion understanding. Eighty children ranging in age from 4 to 11 years were tested. Children displayed a clear improvement with age in both their emotion understanding and language ability. In each age group, there were clear individual differences in emotion understanding and language ability. Age and language ability together explained 72% of emotion understanding variance; 20% of this variance was explained by age alone and 27% by language ability alone. The results are discussed in terms of their theoretical and practical implications.

There is accumulating evidence of a relationship between secure attachment and children's understanding of emotion (Fonagy & Target, 1997; Harris, 1999). The current experiment asked if this relationship is particularly evident when the test of emotion understanding includes attachment-related material or is equally marked on tests with and without attachment-related material. Children ranging from 3-6 years were given a novel test of emotion understanding (the Mother-Infant Separation Test Video) that incorporated provocative attachment themes and also an affectively neutral test of emotion understanding. They performed quite consistently on both types of test-either passing both or failing both. In addition, attachment security, measured concurrently by means of the Separation Anxiety Test, contributed to a correct performance on both tests. This contribution remained when other individual differences were controlled for (age, verbal mental age and gender). Possible explanations of the relationship between attachment and emotion understanding are discussed.
