Emotion understanding, theory of mind, and prosocial orientation: Relations over time in early childhood

Children's and adolescents' social mindfulness in intergroup contexts: The roles of empathy, theory of mind, and inhibitory control in considerate actions

Social mindfulness (SoMi) is recognized as an indirect form of everyday prosocial behavior that involves one's tendency to be appreciative of both one's and others' preferences before making a decision and giving others the opportunity to make their own choices. This study explored how SoMi is differently expressed toward in-group and out-group members among middle-aged children (aged 7-9 years here) and adolescents using an experimental approach. In addition, it examined the relationship among age, SoMi, and sociocognitive abilities, including empathy, theory of mind, and inhibitory control. The results showed that adolescents exhibited SoMi more frequently toward in-group members than did children. In children, theory of mind and age were significantly linked to higher levels of SoMi toward both in-group and out-group members. In addition, there was a positive relationship between children's inhibitory control abilities and their display of SoMi toward in-group members but not toward out-group members. In contrast, among adolescents, only inhibitory control-not theory of mind, age, or empathy-was associated with increased SoMi toward in-group members. Adolescents' SoMi toward out-groups was not correlated with either sociocognitive skills or age. Overall, these findings suggest that socially mindful behaviors in children and adolescents might be shaped by different sociocognitive skills and might vary in how they are directed toward in-group and out-group members. Future research should further investigate the sociocognitive mechanisms underlying these differences in socially mindful behaviors in intergroup context among children and adolescents.

Emotional Adjustment in Children with Vocal Fold Nodules

INTRODUCTION

Vocal fold nodules (VNs) in children are benign, bilateral, callous-like lesions at the junction of the anterior third and posterior two-thirds of the true vocal folds. Chronic, repetitive, and intense vocal behavior is often cited as the primary etiology; however, difficulties with emotional adjustment may predispose some children towards extreme and possibly phonotraumatic vocal activity, thereby contributing secondarily to the development of VNs.

OBJECTIVES

This case-control study examined the association between features of emotional adjustment and VNs in children.

METHODS

Parents of children with VNs (N = 40, Mage = 7.5, SDage = 2.03) and two medical control groups [ie, voice disordered, but not VNs (VDCs; N = 40, Mage= 7.09, SDage = 2.01) and vocally normal controls (VNCs; N = 40, Mage = 7.6, SDage = 1.54)] participated in the study. Features of emotional adjustment were assessed using two inventories: the Parent Rating scale for Reactive and Proactive Aggression and the Revised Child Anxiety and Depression Scale - Parent version.

RESULTS

As compared with the VNCs, children with VNs were significantly more aggressive (P = 0.042, Cohen's d = 0.47) whereas the VDCs were more depressed (P = 0.013, Cohen's d = 0.60). Furthermore, VDCs experienced more separation anxiety than VNs (P = 0.038, Cohen's d = 0.45) and VNCs (P = 0.021, Cohen's d = 0.55). No other significant between-group differences were identified between the VNs and VDCs.

CONCLUSIONS

When present, elevated aggression may represent a risk factor for VNs formation in children, and possibly influence treatment outcomes. Therefore, the current results highlight the importance of understanding the role of emotional adjustment in the evaluation and treatment of dysphonia in children.

Relationship between parental reflective functioning and children's multiple theory of mind in 4- to 7-year-old children with and without developmental language disorder: Parental stress as a mediator

Children with developmental language disorder (DLD) often struggle with theory of mind (ToM). This study explored the link between parental reflective functioning (PRF) and children's ToM, focusing on the mediating role of parental stress (PS). A total of 80 children aged 4-7 years (40 with DLD and 40 with typical language development, TLD) and their parents were included for analysis. Assessments included the WPPSI-IV, NEPSY-II, TEC, and ELT for children and the PRFQ and PSI-SF4 for parents. Results showed that children with DLD performed similarly to their TLD peers in terms of nonverbal intelligence but faced difficulties with cognitive and affective ToM and understanding of emotional terms (UET). Parents of DLD children exhibited low interest and curiosity (PRF components) and high PS, particularly due to dysfunctional interactions and challenging behaviors. Mediation analysis revealed that low parental interest and curiosity negatively affected children's cognitive ToM and UET through increased PS from dysfunctional interactions. These findings highlight the need for early interventions to enhance ToM in children with DLD and support parents in better understanding and interacting with their child. Such interventions can reduce parent-child stress and promote ToM development of children with DLD, aligning with bioecological models of development.

Social Understanding and Friendships in Children with Attention Deficit/Hyperactivity Disorder or Dyslexia

Social understanding relies upon children's experience of the world and their communicative interaction with others. Opportunities to engage in cooperative social interaction, such as friendships, can foster the development of social understanding. Children with attention deficit/hyperactivity disorder (ADHD) and dyslexia often have friendships of poorer quality. The present study examined relationships and differences in social understanding and friendship quality in children with ADHD or dyslexia, in comparison to neurotypically developing children (NTD). Participants were 192 primary-school students (Mage = 9.77, SD = 1.21) from Attica, Greece. Social understanding was measured with second-order and advanced theory of mind (ToM) tasks, and the Bryant's Index of Empathy for Children and Adolescents, while friendships were examined with the Friendship Quality Questionnaire. Children with ADHD scored significantly lower across all positive characteristics of friendship quality, empathy and advanced ToM than those with dyslexia, who in turn scored significantly lower than NTD children. Moreover, children with ADHD performed significantly worse in the second-order ToM tasks compared to children with NTD or dyslexia, while NTD children scored significantly lower in the friendship conflict betrayal subscale compared to both ADHD and dyslexia groups. Multiple regression analyses controlling for learning disability status, gender, and age showed that ToM and perceived empathy predict friendship quality characteristics in all groups of children. Our findings contribute to a better understanding of children's friendship relationships and give insight to parents and professionals involved in children's education, provision, and mental health care.

Sharing and Allocation in Preschool Children: The Roles of Theory of Mind, Anticipated Emotions, and Consequential Emotions

This study investigates the impact of theory of mind, anticipated emotions before actual behavior, and consequential emotions following the behavior on sharing and allocation behavior in 4-6-year-old children. In Experiment 1, 95 children were randomly assigned to three conditions (external emotion expectancy condition, internal emotion expectancy condition, and control condition) to explore the role of cognition and emotions in children's sharing and allocation behaviors. Experiment 2 employed a dictator game to further validate the influence of theory of mind and consequential emotions on behavior. The findings indicated that both anticipated and consequential emotions influence sharing behavior, but neither serves as a key predictor of allocation behavior. Theory of mind influences children's sharing behavior and is related to the fairness of allocation. Children with higher levels of theory of mind tend to rate consequential emotions more positively, while those with lower ratings of consequential emotions are more likely to reconsider sharing after reflection. Notably, theory of mind and emotional factors demonstrate distinct motivational effects on children's prosocial sharing and resource allocation, with negative emotions exhibiting a more pronounced impact on decision-making processes.

The Effect of Social Information Processing, Self-Regulation and Metacognition on Theory of Mind: Path Analysis

OBJECTIVES

The main purpose of the current study was to examine the effects of social information processing, self-regulation, and metacognition variables on ToM using path analysis.

METHODS

For this purpose, path analysis was conducted for the model established according to the relationships between the variables. Theory of mind task battery (ToMTB), Metacognitive Knowledge Interview (McKI), Schultz Test of Emotion Processing-Preliminary Version (STEP-P), and self-regulation scale were administered to 310 children aged 3-5 years.

RESULTS

The results show that social information processing (except STEP-P.P.B, one of the sub-dimensions of the STEP-P scale) has a significant effect on ToM through metacognition and self-regulation.

CONCLUSIONS

In this context, it can be said that social information processing, metacognition, and self-regulation are effective in the development of ToM.

From mindreading to originality: Exploring the relationship between Theory of Mind and Creativity across the lifespan

In the previous psychoeducational literature, many theorists have argued that creativity and originality require the ability to make predictions and assumptions regarding other individuals' ideas. Thus, it has been widely hypothesized that social cognition and theory of mind (ToM) might be a fundamental component or even a prerequisite of creativity. Despite their common grounds, the empirical evidence examining the potential link between ToM and creative thinking throughout their development seems to be indirect, limited, and fragmented. In this respect, this scoping review aimed to collect and synthesize the existing knowledge about the relationship between ToM and creativity at different ages to identify significant literature gaps and generate updated research questions that might guide future research. The search process led to the inclusion, analysis, and collation of 6 relevant studies only, indicating that this research topic has been poorly investigated. Results demonstrated that ToM and creativity are strongly correlated even after partialling out significant mediators, such as age and intelligence. Such a strong association should be further investigated and explained.

The roots of compassion in early childhood: Relationships between theory of mind and attachment representations with empathic concern and prosocial behavior

This study focused on attachment representations and theory of mind as potential developmental origins of individual differences in preschoolers' peer- and adult-directed empathic concern and prosocial behavior. In two experiments, 3- to 6-year-olds were exposed to either a high-distressed or low-distressed adult or child using a laboratory setting (Experiment 1; N = 263) or hypothetical vignettes (Experiment 2; N = 202). Self-reported and coded expressions of empathic concern and prosocial behaviors were used as early indicators of compassion. The findings indicated that children expressed more empathic concern and engaged in more prosocial behavior in the high-distress condition than in the low-distress condition. Children's empathic concern and prosocial behavior increased with age. Secure attachment and theory of mind abilities played significant moderating roles in the association between distress conditions and empathic concern. Children with more advanced theory of mind abilities and secure attachment were better at recognizing the concerns of distressed peers or adults and showed significantly more empathic concern. Resistant and disorganized children exhibited more self-distress in response to others' distress. The implications for early interventions directed at increasing empathic concern and prosocial behavior are discussed.

Compensatory prosocial behavior in high-risk adolescents observing social exclusion: The effects of emotion feedback

Although exposure to violence has been consistently associated with deficits in prosocial behavior among adolescents, effective methods of mitigating these deficits have yet to be identified. The current investigation tested whether prosocial behavior could be promoted by providing adolescents with feedback about the emotional states of others and whether the effects of feedback varied between adolescents who had versus had not experienced violence in the home or in the community. Adolescents aged 8 to 17 years with (n = 87) and without (n = 61) histories of violence exposure completed a virtual social exclusion ball-tossing paradigm in which information about an excluded peer's emotions (sad, angry, or neutral) was experimentally manipulated. Among adolescents with histories of violence exposure, those who received feedback that the peer was sad due to being excluded compensated by throwing the ball more often to that peer. In contrast, adolescents without histories of violence exposure did not engage in compensatory prosocial behavior, instead maintaining a relatively even number of tosses to all players. Findings offer new insight into simple potential methods of eliciting prosocial behavior in adolescents for whom such responding may be compromised and may provide a potential starting point for interventions.

Silencing screaming with screens: The longitudinal relationship between media emotion regulation processes and children's emotional reactivity, emotional knowledge, and empathy

Many parents use screens to regulate their young children's emotions. We know very little, however, about how this parenting practice is related to the development of emotional competencies (i.e., emotional reactivity, emotion knowledge, and empathy) over time. The current longitudinal study examined bidirectional associations between media emotion regulation and various emotional competencies across a 1-year period during early childhood (between ages 3.5 and 4.5 on average). Participants included 269 child/parent dyads who completed a number of in-home tasks and questionnaires. Results revealed that higher levels of media emotion regulation were associated with worse emotional knowledge and empathy and higher emotional reactivity at the cross-sectional level. However, early media emotion regulation was associated with higher levels of child empathy 1 year later. We discuss these results in the context of general parenting practices and encourage future research on the topic with a focus on how these processes develop over time.

Theory of Mind and Young Children's Behaviour: Aggressive, Victimised, Prosocial, and Solitary

Theory of mind (ToM) undergoes significant developments during childhood, particularly between the ages of four and seven years. A growing body of research has indicated that children's social understanding may be related to their social behaviour with peers, in line with Theory Theory which proposes that children's social cognition is influenced by and influences their peer interactions. The current study examined the relationship between ToM and behaviour among 193 children aged 4-7 years. Children carried out a battery of ToM tasks, and teaching staff reported on children's aggressive, prosocial, and solitary behaviour and victimisation experiences. Aggression was not directly related to ToM; prosocial behaviour was positively associated with ToM for girls but not boys. Solitary behaviour and victimisation were negatively related to ToM. When this was broken down by gender, there was only a significant association between solitary behaviour and ToM for boys. When controlling for the relationship between behaviours, the only significant predictor of ToM was solitary behaviour for boys. ToM was also a significant predictor of solitary behaviour for boys, demonstrating that there is a bidirectional relationship at play. The findings highlight the importance of looking across these four behaviour types and understanding the relationship between behaviour profiles and ToM for boys and girls separately.

The link between emotion comprehension and cognitive perspective taking in theory of mind (ToM): a study of preschool children

The study examined the relation between perspective taking embedded in theory of mind (ToM) and emotion comprehension (EC) in young children. Our study involved children from Poland aged 3-6 (N = 99; 54% boys) from public and private kindergartens residing mainly in urban areas, whose parents could mostly be classified as middle class. The children were examined with the Test of Emotion Comprehension (TEC) and three tasks targeting three aspects of ToM: a first-order false belief task, an appearance-reality test, and a mental states opacity task. The results showed similarities in performances between these different measures. However, only the opacity task predicted the emotion comprehension test results (η² = 0.13). The results indicate that the key element of ToM that explains individual differences in children's emotion comprehension is the full-blown understanding of perspective taking, namely that having access to an object under one description does not ensure access to that object under all descriptions. In the research, we took also into account the linguistic side of such specific competences as ToM and EC, which allowed us to see the role of language in scaffolding the development of children's ability to handle such socially fundamental tasks as understanding emotions and epistemic states.

Face masks negatively skew theory of mind judgements

Face masks obscure a significant portion of the face, reducing the amount of information available to gauge the mental states of others-that is, to exercise the Theory of Mind (ToM) capacity. In three experiments, we assessed the effect of face masks on ToM judgements, measuring recognition accuracy, perceived valence, and perceived arousal in various sets of facial expressions comprising 45 different mental states. Significant effects of face masks were found in all three variables. Judgements of all expressions are less accurate when masked, but, while judgements of negative expressions do not show consistent changes in valence or arousal, positive expressions are perceived to be less positive and less intense. In addition, we identified face muscles associated with changes in perceived valence and arousal, shedding light on the mechanisms through which masks impact ToM judgements, which might be relevant for mitigation strategies. We discuss the implications of these findings in the context of the recent pandemic.

Compliance or empathy-What links maternal sensitivity and toddlers' emotional helping?

Emotional helping-that is, helping based on others' emotional distress-has been suggested to be a central prosocial response to others in need. Developmental theorizing proposed that emotional helping has social origins. Whereas research indeed demonstrated a link between maternal sensitivity and children's emotional helping, developmental theories stress different mediating processes. Emotion-sharing theories claim empathic concern to be the crucial link for helping, whereas internalization theories base children's helping on children's compliance. To investigate these hypotheses, the current study explored empathy and compliance as two possible mediators for the relation between maternal sensitivity and children's emotional helping at 18 months of age. Overall, maternal sensitivity was positively related to children's empathy, children's compliance, and children's emotional helping. Interestingly, children's empathy-but not children's compliance-mediated the link between maternal sensitivity and children's emotional helping. These findings deepen our understanding of the psychological processes subserving emotional helping during infancy and support theories that stress the socioemotional origins of children's prosocial behavior.

Visuospatial perspective-taking in social-emotional development: enhancing young children’s mind and emotion understanding via block building training

Background

Theory of Mind (ToM) refers to the ability to represent one's own and others' mental states, and emotion understanding involves appropriately comprehending and responding to others' emotional cues in social interactions. Individual differences in mind and emotion understanding have been associated strongly with verbal ability and interaction and, as such, existing training for children's ToM and emotion understanding is mostly language-based. Building on the literature on embodied cognition, this study proposes that mind and emotion understanding could be facilitated by one's visuospatial experience in simulating other's frames of reference.

Methods

This protocol consists of two training studies. Study 1 will examine if visuospatial perspective-taking training promotes ToM and emotion understanding. Participants will consist of 96 4.5-year-olds and will be randomly assigned to one of two training groups: the altercentric block building group (trained to be visuospatial perspective-takers), or the egocentric block building group (no visuospatial perspective-taking is involved). Study 2 will compare the engagement of visuospatial perspective-taking and verbal interaction in the development of mind and emotion understanding. Participants will consist of 120 4.5-year-olds. They will be randomly assigned to one of three training groups: the socialized altercentric block building (both visuospatial perspective-taking and verbal interaction), the parallel altercentric block building (visuospatial perspective-taking only), or the paired dialogic reading (verbal interaction only).

Conclusions

In terms of theoretical implications, the potential causal relationship between visuospatial perspective-taking and ToM and emotion understanding may shed new insights on what underlies the development of mental state understanding. The findings of this study also have practical implications: researchers and educators may popularize visuospatial perspective-taking training in the form of block-building games if it is found to be effective in complementing conventional language-based theory-of-mind training.

Emotional prosody recognition enhances and progressively complexifies from childhood to adolescence

Emotional prosody results from the dynamic variation of language's acoustic non-verbal aspects that allow people to convey and recognize emotions. The goal of this paper is to understand how this recognition develops from childhood to adolescence. We also aim to investigate how the ability to perceive multiple emotions in the voice matures over time. We tested 133 children and adolescents, aged between 6 and 17 years old, exposed to 4 kinds of linguistically meaningless emotional (anger, fear, happiness, and sadness) and neutral stimuli. Participants were asked to judge the type and intensity of perceived emotion on continuous scales, without a forced choice task. As predicted, a general linear mixed model analysis revealed a significant interaction effect between age and emotion. The ability to recognize emotions significantly increased with age for both emotional and neutral vocalizations. Girls recognized anger better than boys, who instead confused fear with neutral prosody more than girls. Across all ages, only marginally significant differences were found between anger, happiness, and neutral compared to sadness, which was more difficult to recognize. Finally, as age increased, participants were significantly more likely to attribute multiple emotions to emotional prosody, showing that the representation of emotional content becomes increasingly complex. The ability to identify basic emotions in prosody from linguistically meaningless stimuli develops from childhood to adolescence. Interestingly, this maturation was not only evidenced in the accuracy of emotion detection, but also in a complexification of emotion attribution in prosody.

Prosocial Behavior in Toddlerhood: The Contribution of Emotion Knowledge, Theory of Mind, and Language Ability

While scholars have previously investigated the respective contributions of emotional knowledge and language ability to toddlers' prosociality, no studies to date have featured a battery of multiple direct measures assessing both of these abilities plus theory of mind on the one hand, and prosocial behavior on the other hand. In contrast, we conducted the present cross-sectional study with a view to evaluating the unique contributions of each of these three social cognition variables as antecedents of prosocial conduct during toddlerhood, measuring them via a series of individually administered standardized tasks. Furthermore, given that the existing literature documents mixed gender effects, we also set out to explore the role of gender in toddlers' prosociality. Finally, we also controlled for any effects of age on the patterns of association among the key variables. Participants were 127 children aged between 24 and 36 months (M = 29.2 months; SD = 3.5). We identified significant correlations among the variables under study. In addition, stepwise multiple regression analysis suggested that each of the social cognition (SC) abilities – i.e., emotion knowledge, theory of mind, and language - made a unique contribution to explaining variance in prosocial behaviors (PB). These findings show that SC is already associated with PB in toddlerhood and suggest the importance of fostering social cognition competence from the early years, with a view to increasing children's propensity to engage in prosocial conduct.

Growth in emotion understanding across early childhood: A cohort-sequential model of firstborn children across the transition to siblinghood

Emotion understanding develops rapidly in early childhood. Firstborn children (N = 231, 55% girls/45% boys, 86% White, 5% Black, 3% Asian, 4% Latinx, M_age  = 29.92 months) were recruited into a longitudinal study from 2004 to 2008 in the United States and administered a series of tasks assessing eight components of young children's emotion understanding from ages 1 to 5. Cohort sequential analysis across three cohorts (1-, 2-, and 3-year-olds) demonstrated a progression of children's emotion understanding from basic emotion identification to an understanding of false-belief emotions, even after controlling for children's verbal ability. Emotion understanding scores were related to children's theory of mind and parent reports of empathy, but not emotional reactivity, providing evidence of both convergent and discriminant validity.

Sensitivity to Emotion Intensity and Recognition of Emotion Expression in Neurotypical Children

This study assessed two components of face emotion processing: emotion recognition and sensitivity to intensity of emotion expressions and their relation in children age 4 to 12 (N = 216). Results indicated a slower development in the accurate decoding of low intensity expressions compared to high intensity. Between age 4 and 12, children discriminated high intensity expressions better than low ones. The intensity of expression had a stronger impact on overall face expression recognition. High intensity happiness was better recognized than low intensity up to age 11, while children 4 to 12 had difficulties discriminating between high and low intensity sadness. Our results suggest that sensitivity to low intensity expressions acts as a complementary mediator between age and emotion expression recognition, while this was not the case for the recognition of high intensity expressions. These results could help in the development of specific interventions for populations presenting socio-cognitive and emotion difficulties.

Perceptual Access Reasoning (PAR) in Developing a Representational Theory of Mind

An important part of children's social and cognitive development is their understanding that people are psychological beings with internal, mental states including desire, intention, perception, and belief. A full understanding of people as psychological beings requires a representational theory of mind (ToM), which is an understanding that mental states can faithfully represent reality, or misrepresent reality. For the last 35 years, researchers have relied on false‐belief tasks as the gold standard to test children's understanding that beliefs can misrepresent reality. In false‐belief tasks, children are asked to reason about the behavior of agents who have false beliefs about situations. Although a large body of evidence indicates that most children pass false‐belief tasks by the end of the preschool years, the evidence we present in this monograph suggests that most children do not understand false beliefs or, surprisingly, even true beliefs until middle childhood. We argue that young children pass false‐belief tasks without understanding false beliefs by using perceptual access reasoning (PAR). With PAR, children understand that seeing leads to knowing in the moment, but not that knowing also arises from thinking or persists as memory and belief after the situation changes. By the same token, PAR leads children to fail true‐belief tasks. PAR theory can account for performance on other traditional tests of representational ToM and related tasks, and can account for the factors that have been found to correlate with or affect both true‐ and false‐belief performance. The theory provides a new laboratory measure which we label the belief understanding scale (BUS). This scale can distinguish between a child who is operating with PAR versus a child who is understanding beliefs. This scale provides a method needed to allow the study of the development of representational ToM.

In this monograph, we report the outcome of the tests that we have conducted of predictions generated by PAR theory. The findings demonstrated signature PAR limitations in reasoning about the mind during the ages when children are hypothesized to be using PAR. In Chapter II, secondary analyses of the published true‐belief literature revealed that children failed several types of true‐belief tasks.

Chapters III through IX describe new empirical data collected across multiple studies between 2003 and 2014 from 580 children aged 4–7 years, as well as from a small sample of 14 adults. Participants were recruited from the Phoenix, Arizona metropolitan area. All participants were native English‐speakers. Children were recruited from university‐sponsored and community preschools and daycare centers, and from hospital maternity wards. Adults were university students who participated to partially fulfill course requirements for research participation. Sociometric data were collected only in Chapter IX, and are fully reported there.

In Chapter III, minor alterations in task procedures produced wide variations in children's performance in 3‐option false‐belief tasks. In Chapter IV, we report findings which show that the developmental lag between children's understanding ignorance and understanding false belief is longer than the lag reported in previous studies. In Chapter V, children did not distinguish between agents who have false beliefs versus agents who have no beliefs. In Chapter VI, findings showed that children found it no easier to reason about true beliefs than to reason about false beliefs. In Chapter VII, when children were asked to justify their correct answers in false‐belief tasks, they did not reference agents’ false beliefs. Similarly, in Chapter VIII, when children were asked to explain agents’ actions in false‐belief tasks, they did not reference agents’ false beliefs. In Chapter IX, children who were identified as using PAR differed from children who understood beliefs along three dimensions—in levels of social development, inhibitory control, and kindergarten adjustment.

Although the findings need replication and additional studies of alternative interpretations, the collection of results reported in this monograph challenges the prevailing view that representational ToM is in place by the end of the preschool years. Furthermore, the pattern of findings is consistent with the proposal that PAR is the developmental precursor of representational ToM. The current findings also raise questions about claims that infants and toddlers demonstrate ToM‐related abilities, and that representational ToM is innate.

Theory of Mind after Pediatric Traumatic Brain Injury: A Scoping Review

This scoping review aims to synthesize existing literature regarding theory of mind (ToM) outcomes, the neuropathology associated with ToM outcomes, and the relationship between ToM outcomes and social functioning in children and adolescents with traumatic brain injury (TBI). We searched MEDLINE® and PsycINFO databases to identify all literature that examined ToM following pediatric TBI until July 2019. A total of 29 articles met inclusion and exclusion criteria and were included in the results. These articles examined a variety of aspects of ToM, which could be broadly grouped into those focused on cognitive, cognitive-affective, and pragmatic factors. The existing literature suggests that children and adolescents with TBI, compared with their typically developing peers and peers with orthopedic injuries, are more likely to have deficits in ToM. The evidence further shows that the age at which brain injury occurs contributes to ToM disruption. Neuroimaging techniques have offered crucial insights into how TBI may impact ToM performance in children and adolescents. Finally, this review provides evidence that disruption in ToM plays a role in the difficulties in social functioning demonstrated by children and adolescents with TBI. Limitations and gaps in the existing literature warrant future research in this field.

Conceptualizing callous-unemotional traits in preschoolers: Associations with social-emotional competencies and aggressive behavior

BACKGROUND

Extensive empirical evidence suggests that high Callous-Unemotional (CU) traits in childhood and adolescence can reliably identify individuals at risk for antisocial outcomes. The present study addresses research gaps by investigating the factor structure of CU traits in children at preschool age.

METHODS

The sample includes 371 children (49.6% female, M age = 4.7, SD = 0.69). Using the Inventory of Callous-Unemotional-Traits (ICU), six alternative confirmatory factor analyses were conducted to find the best fitting model for our preschool sample. Children's level of emotional competence and aggressive behavior was assed using a German questionnaire, the Behavior Rating Scales for Preschoolers (Verhaltensskalen für das Kindergartenalter, VSK) in a preschool teachers' rating. Post hoc cluster analytic strategies and ANOVA were applied to identify groups of children with regard to their combination of social-emotional competences and CU traits, and to examine associations with aggressive behavior.

RESULTS

Results indicate that a two-factor model revealed the best fit to our data, including a callous and an uncaring factor using 12 of the original 24 ICU items. Cluster analytic strategies reveal a risk group of children demonstrating high rates of callousness and uncaring combined with weak emotion knowledge/empathy and social competence. ANOVA shows that children in the risk group demonstrate the highest levels of aggressive behavior.

CONCLUSIONS

Group characteristics indicate that the construct of CU traits in early childhood may be nothing other than a social-emotional developmental deficit.

Factors Facilitating Early Emotion Understanding Development: Contributions to Individual Differences

Children's emotion understanding is crucial for healthy social and academic development. The behaviors influenced by emotion understanding in childhood have received much attention, but less focus has been placed on factors that may predict individual differences in emotion understanding, the principle issue addressed in the current review. A more thorough understanding of the developmental underpinnings of this skill may allow for better prediction of emotion understanding, and for interventions to improve emotion understanding early in development. Here, we present theoretical arguments for the substantial roles of three aspects of children's environments in development of emotion understanding: family expressiveness, discussions about emotions, and language development, and we discuss how these are interrelated. Ultimately, this may aid in predicting the effects of environmental influences on development of emotion understanding more broadly, and the mechanisms by which they do so.

Creating Compassion: Using Art for Empathy Learning with Urban Youth

Social-emotional learning (SEL) curricula are being increasingly implemented with young children; however, access to comprehensive programs can be prohibitive for programs limited by finances, time, or other factors. This article describes an exploratory case study that investigates the use of creative activity in the direct promotion of empathy and indirect promotion of other social-emotional skills for early elementary children in an urban-based after-school setting. A novel curriculum, Creating Compassion, which combines art engagement with explicit behavioral instruction, serves as a promising avenue for social-emotional skill development, and has particular importance for children from low-income households. Five children from racially minoritized backgrounds in grades kindergarten and first attended the Creating Compassion group intervention. Group-level data and individual data of direct behavior ratings suggested a modest increase in empathy development, responsible decision-making, and self-management skills and thereby provide a preliminary basis for further effectiveness investigation. Suggestions for future research in this area are discussed in addition to social justice implications.

Measurement of Cognition for the National Children's Study

The National Children's Study Cognitive Health Domain Team developed detailed plans for assessing cognition longitudinally from infancy to early adulthood. These plans identify high-priority aspects of cognition that can be measured efficiently and effectively, and we believe they can serve as a model for future large-scale longitudinal research. For infancy and toddlerhood, we proposed several paradigms that collectively allowed us to assess six broad cognitive constructs: (1) executive function skills, (2) episodic memory, (3) language, (4) processing speed, (5) spatial and numerical processing, and (6) social cognition. In some cases, different trial sequences within a paradigm allow for the simultaneous assessment of multiple cognitive skills (e.g., executive function skills and processing speed). We define each construct, summarize its significance for understanding developmental outcomes, discuss the feasibility of its assessment throughout development, and present our plan for measuring specific skills at different ages. Given the need for well-validated, direct behavioral measures of cognition that can be used in large-scale longitudinal studies, especially from birth to age 3 years, we also initiated three projects focused on the development of new measures.

Prosocial lying in children between 4 and 11 years of age: The role of emotional understanding and empathy

This study examined whether emotional understanding and empathy were predictors of prosocial lying in children aged 4 to 11 years. A total of 144 children participated in the study. To assess children's prosocial lying, we used the Helping Scenario, a classical experimental paradigm that allows children to lie to help others at their own expense. Children's emotional understanding was assessed using the Test of Emotion Comprehension, a test that measures the nine components of emotional understanding. Children's empathy was assessed using the Griffith Empathy Measure, a questionnaire completed by parents that measures affective and cognitive empathy. Results indicated that emotional understanding plays a crucial role in the development of children's ability to produce prosocial lies from 4 to 11 years of age. However, we found no significant relationship between empathy and prosocial lying. Finally, our results confirm that as children grew up, they lied more and more effectively. Overall, the results allow us to better understand the factors that contribute to the emergence and development of children's ability to produce prosocial lies.

Conscience and theory of mind in children aged 4 to 7 years

Associations between three dimensions of early conscience-moral reasoning, the capacity to experience guilt, and the moral self-and theory of mind (ToM) were examined in children aged 4-7 years (N = 80). Participants were administered a task assessing their understanding of the intentions and actions of a transgressor in situations entailing intentional and accidental wrongdoing, a moral self scale, and a battery of first-order and second-order false belief tasks. Children's capacity to experience guilt was measured via parent report. Expressive vocabulary was also measured. Repeated-measures analysis of covariance with ToM, age, and their interaction as covariates revealed that children who had higher ToM scores attributed more positive intentions to the accidental transgressor than to the intentional transgressor and judged the intentional transgressor's action as more wrongful than children who scored lower on these tasks. Ηierarchical regression analyses also indicated that a more advanced ToM performance predicted higher levels of guilt and the moral self after accounting for age and expressive vocabulary.

Primary caregiver emotional expressiveness relates to toddler emotion understanding

The present study examined the impact of emotional expressiveness in toddlers' environments on their emotion understanding. Primary caregivers of 35 toddlers completed two surveys regarding the family's emotional expressiveness and the primary caregiver's expressivity. Toddlers participated in the Affective Knowledge Test to measure emotion understanding. Toddler emotion understanding related to primary caregiver expressivity, but not family expressiveness. Further, toddler emotion understanding related to primary caregiver Impulse Strength, but not Negative or Positive Emotionality. This suggests that primary caregivers with more impulsive emotional response tendencies may help their children to identify associations between emotional events and reactions.

The personality dispositions and resting-state neural correlates associated with aggressive children

Despite aggression being detrimental to children's physical health, mental health and social development, the dispositional and neurological antecedents of aggression in the child are poorly understood. Here we examined the relationship between trait aggression as measured by Buss and Warren's Aggression Questionnaire and personality traits measured with Big Five Questionnaire for Children in 77 primary-school children and recorded resting-state brain activity (fractional amplitude of low-frequency fluctuations [fALFF]) and resting-state functional connectivity (rsFC) using functional magnetic resonance imaging. The present results showed that trait aggression was negatively correlated with agreeableness and positively correlated with neuroticism. The brain analyses showed that children with a higher propensity for aggression had a lower fALFF mainly in the left superior temporal gyrus, right parahippocampal gyrus and left supramarginal gyrus. Physical and total aggressions were negatively associated with rsFC between the right parahippocampal gyrus and the right putamen. Further analysis revealed that this rsFC could moderate the influence of neuroticism on total aggression. Moreover, the results suggest the presence of a sex difference in the neurodevelopmental mechanisms underlying aggression in middle childhood. Overall, our findings indicate that aggressive children have lower agreeableness and higher neuroticism, and the underlying neural systems are mainly implicated in social judgment and empathy.

Theory of Mind and diverse intelligences in 4-year-olds: Modelling associations of false beliefs with children's numerate-spatial, verbal, and social intelligence

Theory of Mind (ToM) and the structure of intelligence were investigated in 115 4-year-olds. Specifically, we asked whether children's intelligence involves both general and specific aspects and whether standard ToM measures of false belief can serve as indicators of social intelligence. Psychometric intelligence and children's domain-specific understanding of number concepts and of mental states (false belief) were measured in the laboratory; communication and social skills were assessed through mothers' report. A confirmatory factor analysis revealed poor fit for a one-factor model, but good fit for a model with three correlated factors, suggesting that children's intelligence involves both general and specific aspects. Numerate-spatial and verbal intelligence were correlated (.70), and social intelligence correlated to a stronger degree with verbal (.66) than with numerate-spatial intelligence (.37). Laboratory assessment of false belief and mothers' reports about children's social skills loaded on a single factor, pointing to real-world consequences of ToM abilities. Statement of contribution What is already known on this subject? The structure of intelligence in 4-year-olds comprises domain-general and domain-specific dimensions. Some domain-specific dimensions are numerate-spatial, verbal, and social intelligence. What does this study add? Theory of Mind emerges as an aspect of children's social intelligence. Social intelligence (including Theory of Mind) is related to children's numerate-spatial abilities.

Interpretive theory of mind and empathic prosocial moral reasoning

Theory of mind (ToM) is seen as fundamental in development of social understanding. The study proposes that interpretive theory of mind (iToM), which follows ToM attainment, underlies important shifts towards mature social understanding. With ToM found to predict the needs orientation in prosocial moral reasoning (PMR), we hypothesized that iToM, unlike ToM, would account for PMR orientations requiring empathic reasoning. Those with iToM recognize the role of subjective processes, such as interpretation, in knowing. They can invoke others' subjective processes, not just their physical perspectives, in explaining others' decisions. A study with 225 7- to 11-year-old children (M_age  = 9.04, SD = 0.91) found that iToM, but not ToM, predicted empathic and internalized values PMR orientations when controlling for age, emotion understanding and inhibitory control. These findings show that iToM attainment plays a unique role in developing social understanding such as reflected in empathic reasoning-based PMR orientations.

Early socioemotional competence, psychopathology, and latent class profiles of reparative prosocial behaviors from preschool through early adolescence

Children who have difficulty using reparative behaviors following transgressions display a wide range of poorer social and emotional outcomes. Despite the importance of reparative skills, no study has charted the developmental trajectory of these behaviors or pinpointed predictors of poorer reparative abilities. To address these gaps in the literature, this study applied growth mixture modeling to parent reports of children's reparative behaviors (N = 230) in a 9-year longitudinal data set spanning from preschool to early adolescence. Three distinct trajectories of reparative behaviors were found: a low-stable, moderate-stable, and high-stable latent class. Poorer emotion understanding, social withdrawal, social rejection, and maladaptive guilt in the preschool period predicted membership in a low-stable reparative trajectory. Externalizing diagnoses, particularly conduct disorder and oppositional defiant disorder, also predicted membership in a low-stable reparative trajectory. Preschool-onset depression predicted membership in a low-stable reparative trajectory through high levels of maladaptive guilt. The findings from this study suggest that socioemotional deficits in the preschool period set children on longstanding trajectories of impaired reparative responding. Thus, emotion understanding, social functioning, maladaptive guilt, and early psychiatric symptoms should be targeted in early preventive interventions.

Intermodal emotion matching at 15 months, but not 9 or 21 months, predicts early childhood emotion understanding: A longitudinal investigation

Emotion understanding is a crucial skill for early social development, yet little is known regarding longitudinal development of this skill from infancy to early childhood. To address this issue, the present longitudinal study followed 40 participants from 9 to 30 months. Intermodal emotion matching was assessed using eye tracking at 9, 15, and 21 months, and emotion understanding was measured using the Affective Knowledge Test at 30 months of age. A novelty preference on the emotion matching task at 15 months (but not at 9 or 21 months) significantly predicted emotion understanding performance at 30 months. However, linear and quadratic trajectories for emotion matching development across 9- to 21-months did not predict later emotion understanding. No gender differences were observed in emotion matching or emotion understanding. These results hold implications for better understanding how infant emotion matching may relate to later emotion understanding, and the role that infant emotion perception may play in early emotional development.

Developing an understanding of others' emotional states: Relations among affective theory of mind and empathy measures in early childhood

Theory of mind (ToM) consists of cognitive and affective components; however, few studies have evaluated the coherence of affective ToM measures and their associations with empathy. This research examined the relations among affective ToM tasks and assessments of empathy, measured directly and via parent reports in 4- to 6-year-olds. Children (N = 117) completed: an Appearance-Reality Emotion Task, an adapted Reading the Mind in the Eyes Test, an Affective Stories Task, and an empathy task. Parents reported on children's ToM and empathy, and language was assessed using a Picture Vocabulary Test. Controlling for language, no relationships were found among affective ToM measures and children's age was only related to the Affective Stories Task. Further, controlling for age, only parent-reported empathy was associated with the Appearance-Reality Emotion Task. Once vocabulary and age were controlled, measures of affective ToM are unrelated and different developmental patterns emerged across measures. Statement of contribution What is already known on this subject Affective theory of mind is a distinct subcomponent of theory of mind that corresponds to an independent developmental mechanism. However, little research has been conducted on affective ToM, its developmental trajectory during the preschool years, its assessment, and its relationship with related constructs, such as empathy. What the present study adds Children's performance on affective ToM tasks was unrelated once age and language abilities were accounted for. Thus, there is a need to examine affective ToM and its measurement more extensively to ensure we are effectively capturing this construct. This study was the first to establish a Preschool Reading the Mind in the Eyes Task that uses images of children and pictorial response options and an Affective Stories Task that captures age-related changes in affective ToM beyond language skills.

Prosocial behavior relates to the rate and timing of cortical thinning from adolescence to young adulthood

Prosocial behavior, or voluntary actions that intentionally benefit others, relate to desirable developmental outcomes such as peer acceptance, while lack of prosocial behavior has been associated with several neurodevelopmental disorders. Mapping the biological foundations of prosociality may thus aid our understanding of both normal and abnormal development, yet how prosociality relates to cortical development is largely unknown. Here, relations between prosociality, as measured by the Strengths and Difficulties Questionnaire (self-report), and changes in thickness across the cortical mantle were examined using mixed-effects models. The sample consisted of 169 healthy individuals (92 females) aged 12-26 with repeated MRI from up to 3 time points, at approximately 3-year intervals (301 scans). In regions associated with social cognition and behavioral control, higher prosociality was associated with greater cortical thinning during early-to-middle adolescence, followed by attenuation of this process during the transition to young adulthood. Comparatively, lower prosociality was related to initially slower thinning, followed by comparatively protracted thinning into the mid-twenties. This study showed that prosocial behavior is associated with regional development of cortical thickness in adolescence and young adulthood. The results suggest that the rate of thinning in these regions, as well as its timing, may be factors related to prosocial behavior.

Emotion Knowledge, Theory of Mind, and Language in Young Children: Testing a Comprehensive Conceptual Model

Numerous studies suggest that both emotion knowledge and language abilities are powerfully related to young children's theory of mind. Nonetheless, the magnitude and direction of the associations between language, emotion knowledge, and theory-of-mind performance in the first years of life are still debated. Hence, the aim of this study was to assess the direct effects of emotion knowledge and language on theory-of-mind scores in 2- and 3-year-old children. A sample of 139 children, aged between 24 and 47 months (M = 35.5 months; SD = 6.73), were directly administered measures of emotion knowledge, theory of mind, and language. We conducted structural equation modeling (SEM) to evaluate the effects of these variables within a single comprehensive framework, while also controlling for any effects of age and gender. The proposed structural equation model provided an excellent fit for the data, indicating that both children's emotion knowledge, and their language ability had direct positive effects on theory of mind scores. In addition, age was found to wield statistically significant effects on all the variables under study, whereas gender was not significantly associated with any of them. These findings suggest the importance of fostering young children's emotion knowledge and language ability with a view to enhancing their comprehension of mental states.
