How to Foster Toddlers' Mental-State Talk, Emotion Understanding, and Prosocial Behavior: A Conversation-Based Intervention at Nursery School

Nonverbal emotion perception and vocabulary in late infancy

Language has been proposed as a potential mechanism for young children's developing understanding of emotion. However, much remains unknown about this relation at an individual difference level. The present study investigated 15- to 18-month-old infants' perception of emotions across multiple pairs of faces. Parents reported their child's productive vocabulary, and infants participated in a non-linguistic emotion perception task via an eye tracker. Infant vocabulary did not predict nonverbal emotion perception when accounting for infant age, gender, and general object perception ability (β = -0.15, p = .300). However, we observed a gender difference: Only girls' vocabulary scores related to nonverbal emotion perception when controlling for age and general object perception ability (β = 0.42, p = .024). Further, boys showed a stronger preference for the novel emotion face vs. girls (t(48) = 2.35, p = .023, d= 0.67). These data suggest that pathways of processing emotional information (e.g., using language vs visual information) may differ for girls and boys in late infancy.

"I know what's inside because you showed me": Training 33-month-old children to attribute knowledge and ignorance to themselves and others

The present study investigated the role of language in two-year-old children's early understanding of knowledge and ignorance. An intense microgenetic training consisting of 12 to 14 training sessions within six to seven weeks was conducted between 33 and 36 months. One training group experienced and participated in discourse about epistemic states in theoretically relevant situations which highlighted, for instance, the relation between seeing and knowing or contrasts between different people's knowledge states. The other training group was trained on complement syntax using sentence repetition tasks. An age-matched control group received no training. The complement syntax training was not effective in improving complement syntax competence more than in the other two groups. In contrast, the mental state training led to higher improvements in the mental state training group than in the other two groups on tasks assessing comprehension of the targeted concepts (e.g., comprehension of the seeing-knowing relation). The mental state training also had an effect on children's metacognitive awareness of their own ignorance which was, however, not independent of complement syntax competence assessed at 33 months. No effect was obtained on epistemic perspective-taking skills. Our findings indicate that the use of mental state language in discourse promotes children's acquisition of epistemic concepts even before their third birthday.

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.

Prosocial Behavior in Preschoolers: Effects of Early Socialization Experiences With Peers

Over the last decades, many studies had focused on the psychological outcomes of children who have received early socialization outside of the family context, highlighting that the daycare experience can both positively and negatively influence the child’s social-emotional development. Despite the number of studies conducted, there is a lack of observational research on this topic. The purpose of this study is to investigate whether the early daycare experience can influence the prosocial behaviors that children exhibit during free-play social interactions with peers, focusing on their quantity and quality. In addition, the associations between the enactment of prosocial behaviors and social-emotional and behavioral competence were investigated. 160 preschoolers, 77 of whom had previously attended daycare, participated in the study and were focally observed during two free play sessions with peers. Each prosocial behavior was identified and subsequently classified using a coding scheme designed to consider the self-initiated or required origin of prosocial actions and their underlying motive. Emotion comprehension was measured using a standardized test, while social-emotional and behavioral competence was assessed using a questionnaire filled out by teachers. The main findings showed that children who had attended daycare had higher anger and aggression scores than those who had not, who, in turn, were rated by their teachers as having more internalizing behaviors. These characteristics seemed to account for the differences found in the tendency to act prosocial acts in response to a peer’s request, which was lower in children who had a previous daycare experience. Moreover, early socialization outside of the family context appeared to foster the comprehension of others’ intent to achieve emotional or instrumental personal goals and, at the same time, to reduce conventional/affiliative prosocial acts. Overall, this study suggested that the incidental effects of daycare on prosocial behavior might be canceled due to the peculiar social-emotional and behavioral characteristics of the two groups of children.

Adolescents' Resilience During COVID-19 Pandemic and Its Mediating Role in the Association Between SEL Skills and Mental Health

The main purpose of this paper is to investigate the role of social and emotional learning (SEL) skills and resilience in explaining mental health in male and female adolescents, during the COVID-19 pandemic. Three self-report questionnaires were administered to 778 participants aged between 11 and 16 years (mean age = 12.73 years; SD = 1.73) and recruited from 18 schools in Northern Italy. The SSIS-SELb-S and the CD-RISC 10 assessed SEL and resilience skills respectively, while the Strengths and Difficulties Questionnaire (SDQ) was used to measure mental health in terms of internalizing problems, externalizing problems, and prosocial behavior. We found that SEL and resilience skills were positively and significantly associated with each other, negatively associated with internalizing and externalizing problems, and positively related to prosocial behavior. Three linear regression analyses showed the significant role of resilience, age, and gender in explaining the variance of internalizing problems; the significant role of SEL skills, resilience, age, and gender in explaining the variance of externalizing problems; and the role of SEL skills, age, and gender in explaining prosocial behavior. Importantly, we found that resilience fully mediated the relationship between SEL skills and internalizing problems, partially mediated the relationship between SEL skills and externalizing problems and didn't mediate the relationship between SEL skills and prosocial behavior. The paper concludes with a discussion of the limitations of the study as well as its practical implications.

Evidence for similar conceptual progress across diverse cultures in children’s understanding of emotion

Research with adults has increasingly moved beyond the focus on a small set of allegedly basic emotions, each associated with a signature facial expression. That expansion has been accompanied by a greater emphasis on the potential variability of emotion concepts across different cultural settings. In this conceptual review of children’s understanding of emotion, we argue that it is also important in developmental research to look beyond the small set of emotions associated with distinctive facial expressions. At the same time, we caution against any premature rejection of a universalist approach to children’s understanding of emotion. We review three different lines of evidence in support of this stance: (1) children’s ability to appropriately cite situational elicitors for emotions beyond the basic set; (2) their developing understanding of the relations between emotions and other mental processes; and (3) their realization that a person’s facially expressed emotion may not indicate their felt emotion. In each of these three domains, we target studies that have included children from a variety of cultures to assess how far they respond similarly or differently. We conclude that there is robust evidence for similar conceptual progress in children’s understanding of emotion across a range of cultural settings.

Emotion Words in Early Childhood: A Language Transcript Analysis

Children learn the abstract, challenging categories of emotions from young ages, and it has recently been suggested that language (and more specifically emotion words) may aid this learning. To examine the language that young children hear and produce as they're learning emotion categories, the present study examined nearly 2,000 transcripts from 179 children ranging from 15- to 47-months from the Child Language Data Exchange System (CHILDES). Results provide key descriptive, developmental, and predictive information regarding child emotion language production, including the finding that child emotion word production was predicted by mothers' emotion word production (β=.21, p<.001), but not by child or mother language complexity (β=.01, p=.690; β=.00, p=.872). Frequency of specific emotion words are presented, as are developmental trends in early emotion language production and input. These results improve the understanding of children's daily emotional language environments and may inform theories of emotional development.

Promoting prosocial behavior in toddlerhood: A conversation-based intervention at nursery

The awareness that prosocial skills begin to develop during the early years, with lasting implications for social lives, underpins increasing efforts to find ways of promoting prosocial behavior in children. Nevertheless, few such intervention studies have been conducted with toddlers in educational settings. Following the line of inquiry that examines the role of conversation about inner states in the early development of socioemotional competence, the current study makes an original contribution by evaluating the efficacy of a conversational intervention (TEPP, Toddlers Empathy Prosociality Program) in fostering prosocial conduct in young children. A total of 142 toddlers (M_age = 29.78 months, range = 22-36) participated in a 2-month program during which specially trained teachers read prosocial stories to small groups of children and then involved the children in conversations about inner states and prosocial behavior (Condition 1), in conversations about concrete actions and physical states (Condition 2), or in free play activities (Condition 3). Children in Condition 1 were found to outperform their peers in Conditions 2 and 3 on both direct and indirect measures of prosocial behavior. Gender had a further slight influence on the study outcomes. Overall, the results confirmed that intervention based on conversation about inner states and prosocial actions can enhance the development of prosocial skills in toddlers, encouraging the implementation of early education programs targeting prosociality among peers.

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 continuous impact of cognitive flexibility on the development of emotion understanding in children aged 4 and 5 years: A longitudinal study

The current study investigated the impact of cognitive flexibility on the development of emotion understanding using a longitudinal tracking study. A total of 98 children aged 4 and 5 years were tested for cognitive flexibility, emotion understanding, and verbal ability across three time points within a year. The cross-lagged analyses indicated that early cognitive flexibility played a predictive role in the development of emotion understanding. More precisely, cognitive flexibility at Time 1 predicted emotion understanding at Time 2 and Time 3, and cognitive flexibility at Time 2 predicted emotion understanding at Time 3. Furthermore, mediation analysis showed that verbal ability mediated the impact of cognitive flexibility on emotion understanding. Early cognitive flexibility contributed to later emotion understanding by improving children's verbal ability. These findings suggest that there is a verbal ability-mediated pathway from cognitive flexibility to emotion understanding that provides a new perspective for the development mechanism of children's emotion understanding.

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.

Empathy in Toddlers: The Role of Emotion Regulation, Language Ability, and Maternal Emotion Socialization Style

We investigated, through a cross-sectional study, whether and to what extent toddlers' empathy is associated with a set of individual and family factors known to foster positive social skills in early childhood: children's own emotion regulation, language ability, and maternal emotion socialization style. Participants were 320 toddlers (M _age = 28.8 months; SD = 3.55) and their mothers. The children came from middle-SES families and were recruited at 34 infant-toddler centers. We used parent-report measures to assess the toddlers' competences and a self-report questionnaire to evaluate maternal emotion socialization style (coaching vs. dismissing). Toddlers' empathic responses, as reported by their mothers, were positively and significantly correlated, respectively, with their positive emotion regulation, language skills, and maternal emotion-coaching style. Stepwise regression analysis revealed that emotion regulation and maternal emotion-coaching style contributed to explaining variance in toddlers' empathy, after controlling for the effects of children's age and language ability. Moderation analysis showed that emotion regulation skills did not moderate the relationship between maternal emotion-coaching style and children's empathy. We discuss the implications of these findings.

The link between parental mental state talk and children's lying: An indirect effect via false belief understanding

Past research shows that parental mental state talk (MST) is closely associated with children's theory-of-mind (ToM) understanding. The current study extends previous work by investigating whether parental MST is also associated with children's ToM in action (i.e., lying). A total of 90 Singaporean 3- to 5-year-olds participated in this study with their parents. Parental MST was measured using a storytelling task with a wordless picture book. Mediation analysis revealed an indirect effect: Children's ToM understanding served as a mediator in the path between parental MST and children's lying, whereas there was no significant direct effect of parental MST on children's lying. This study is the first to focus on the relation between parental MST and ToM in an applied setting. Our findings suggest that parental MST can help children to develop sociocognitive skills, which in turn can help children to gain the insight that lying may be used as a strategy for personal gain.

Preschool Teachers' Socialization of Emotion Knowledge: Considering Socioeconomic Risk

Emotion knowledge supports early school success. Socializers' emotions, contingent reactions to emotions, emotion language, and beliefs about emotions can contribute to preschoolers' emotion knowledge, but more is known about parents' contributions than teachers'. We expected teachers' emotion socialization findings to parallel those in the parent literature, with potential moderation by classroom-level socioeconomic risk. Participants included 85 teachers and 327 preschoolers in high or low socioeconomic risk classrooms. Children's emotion knowledge was assessed twice. Teachers reported on emotional expressiveness, reactions to children's emotions, and emotion socialization beliefs. Their emotion language during book reading was codified. Hierarchical linear models predicted end-of-year emotion knowledge via emotion socialization, risk, and their interactions, controlling for child age, gender, and beginning-of-year emotion knowledge. Only one finding resembled the parent literature; most were specific to high socioeconomic risk classrooms, highlighting the importance of context in emotion socialization. Applications, limitations, and suggestions for future research are considered.

Language Games and Social Cognition: Revisiting Bruner

This paper discusses the notion of language games as cultural practices in children's early linguistic and socio-cognitive development. First, we trace the emergence of this concept in Jerome Bruner's experimental and theoretical work at Oxford University in the 1960s, work that was informed by the thinking of Wittgenstein and Austin, amongst others. Second, we provide a systematic historical account of how Bruner has influenced more recent research traditions in developmental psychology, especially in the field of social cognition. Finally, we hone in on one specific approach within this field developed by the Laboratory for Developmental and Educational Studies in Psychology at the University of Milano Bicocca.

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.

Toddlers imitate prosocial demonstrations in bystander but not transgressor contexts

Although prosocial abilities are associated with a wide range of healthy outcomes, few studies have experimentally examined socialization practices that may cause increased prosocial responding. The purpose of this study was to investigate conditions under which 2- and 3-year-old children can acquire prosocial behaviors through imitation. In Study 1 (N = 53), toddlers in the experimental condition watched a video of an adult comfort a woman in distress by performing a novel prosocial action without depicting how the woman was hurt. Parents then pretended they hurt their own finger and feigned distress. Children in the experimental condition were more likely to imitate the novel action relative to two control groups: (a) children who did not watch the video but witnessed a distressed parent, and (b) children who watched the video but witnessed parents engage in a neutral interaction. Thus, in a bystander context where children witnessed parent distress, toddlers imitated a general demonstration of how to respond prosocially to distress and applied this information to a specific distress scenario. In Study 2 (N = 54), the procedures were identical to those in the first study except that children were led to believe that they had transgressed to cause parent distress. In a transgressor context, children in the experimental condition were not more likely to imitate the prosocial behavior relative to children in either control group. These studies demonstrate that whether or not children have caused a victim's distress greatly affects their ability to apply a socially learned prosocial behavior, possibly due to self-conscious emotions such as guilt and shame.

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.

Emotional functioning and the development of internalizing and externalizing problems in young boys with and without autism spectrum disorder

Children with autism spectrum disorder are at risk of developing internalizing and externalizing problems. However, information on early development of behavior problems and the contributing role of emotional functioning in preschool children with autism spectrum disorder is scarce. This study collected data of boys with and without autism spectrum disorder (N = 156; age: 2-6 years) over three consecutive years (three waves), about their internalizing and externalizing symptoms and emotional functioning (i.e. emotion control, recognition, and vocabulary), using parent-report questionnaires. No age effect was found on internalizing or externalizing problems for boys with and without autism spectrum disorder. Boys with autism spectrum disorder displayed more behavior problems than their typically developing peers and showed lower levels of emotional functioning. Better emotion control and improved emotion recognition were associated with a decrease in problem behaviors for boys with and without autism spectrum disorder, whereas improved emotion vocabulary was uniquely related to a decrease in externalizing problems in boys with autism spectrum disorder. Our findings suggest that boys with and without autism spectrum disorder showed similar developmental courses of internalizing and externalizing problems. However, lower levels of emotional functioning were already more pronounced in boys with autism spectrum disorder at a young age. This contributes to higher levels of behavior problems.

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.

Parents' Use of Internal State Language with Toddlers at High and Low Genetic Risk for Autism Spectrum Disorder

Parents of toddlers with an older sibling with autism spectrum disorder (ASD; high risk, HR) and parents of low risk (LR) toddlers with typically-developing older siblings read a wordless picture book to their child at 22 and 28 months. Parents' and toddlers' internal state language (ISL) was coded; parents reported on toddlers' use of ISL. Diagnostic assessments conducted at 36 months identified three groups: ASD, HR-noASD, LR. Parents did not differ in overall ISL, but parents of toddlers with later ASD attempted to elicit ISL from their children less than parents of LR toddlers. Toddlers increased their use of ISL with age, but those with ASD had lower scores and less age-related improvement than children in the other two groups.

The Relation Between Emotion Understanding and Theory of Mind in Children Aged 3 to 8: The Key Role of Language

Although a significant body of research has investigated the relationships among children’s emotion understanding (EU), theory of mind (ToM), and language abilities. As far as we know, no study to date has been conducted with a sizeable sample of both preschool and school-age children exploring the direct effect of EU on ToM when the role of language was evaluated as a potential exogenous factor in a single comprehensive model. Participants in the current study were 389 children (age range: 37–97 months, M = 60.79 months; SD = 12.66), to whom a False-Belief understanding battery, the Test of Emotion Comprehension, and the Peabody Test were administered. Children’s EU, ToM, and language ability (receptive vocabulary) were positively correlated. Furthermore, EU scores explained variability in ToM scores independently of participants’ age and gender. Finally, language was found to play a crucial role in both explaining variance in ToM scores and in mediating the relationship between EU and ToM. We discuss the theoretical and educational implications of these outcomes, particularly in relation to offering social and emotional learning programs through schools.

The Construction of Self in Relationships: Narratives and References to Mental States during Picture-Book Reading Interactions between Mothers and Children

Previous studies showed that mothers vary in the way in which they discuss past experiences with their children, since they can exhibit narrative (elaborative) or paradigmatic (repetitive) styles to different extents. Given this background, the aim of the present study was to analyze differences in the mothers' use of narrative styles and mental state language (MSL), as a function of children's age and gender. Thirty dyads consisting of mothers and their 4- to 6-year-old children were observed during a picture-book reading interaction. Maternal utterances were coded according to the categories described by Tessler and Nelson (1994), classifying each mother as Narrative or Paradigmatic. Eight categories of MSL were analyzed: perceptual, emotional (positive and negative), volitional, cognitive, communicative, and moral. The results confirmed the existence of the two maternal styles observed in the earlier studies. Importantly, we found that the mothers of younger children were more narrative than paradigmatic, whereas the opposite pattern occurred for the mothers of older children (they were more paradigmatic than narrative). As concerns MSL, the results indicated that the use of communicative terms was significantly more frequent for narrative than for paradigmatic mothers, and decreased linearly with children's age. Lastly, the mothers of younger children referred their MSL more frequently to the book characters than to themselves or to the child. Taken together, these results support the idea that mothers adapt their narrative styles and MSL input to the growing abilities of their children, therefore contributing to the development of social understanding.

Happy faces, sad faces: Emotion understanding in toddlers and preschoolers with language impairments

BACKGROUND

The capacity for emotion recognition and understanding is crucial for daily social functioning. We examined to what extent this capacity is impaired in young children with a Language Impairment (LI). In typical development, children learn to recognize emotions in faces and situations through social experiences and social learning. Children with LI have less access to these experiences and are therefore expected to fall behind their peers without LI.

METHOD

In this study, 89 preschool children with LI and 202 children without LI (mean age 3 years and 10 months in both groups) were tested on three indices for facial emotion recognition (discrimination, identification, and attribution in emotion evoking situations). Parents reported on their children's emotion vocabulary and ability to talk about their own emotions.

RESULTS

Preschoolers with and without LI performed similarly on the non-verbal task for emotion discrimination. Children with LI fell behind their peers without LI on both other tasks for emotion recognition that involved labelling the four basic emotions (happy, sad, angry, fear). The outcomes of these two tasks were also related to children's level of emotion language.

IMPLICATIONS

These outcomes emphasize the importance of 'emotion talk' at the youngest age possible for children with LI.

False-Belief Understanding and Language Ability Mediate the Relationship between Emotion Comprehension and Prosocial Orientation in Preschoolers

Emotion comprehension (EC) is known to be a key correlate and predictor of prosociality from early childhood. In the present study, we examined this relationship within the broad theoretical construct of social understanding which includes a number of socio-emotional skills, as well as cognitive and linguistic abilities. Theory of mind, especially false-belief understanding, has been found to be positively correlated with both EC and prosocial orientation. Similarly, language ability is known to play a key role in children's socio-emotional development. The combined contribution of false-belief understanding and language to explaining the relationship between EC and prosociality has yet to be investigated. Thus, in the current study, we conducted an in-depth exploration of how preschoolers' false-belief understanding and language ability each contribute to modeling the relationship between children's comprehension of emotion and their disposition to act prosocially toward others, after controlling for age and gender. Participants were 101 4- to 6-year-old children (54% boys), who were administered measures of language ability, false-belief understanding, EC and prosocial orientation. Multiple mediation analysis of the data suggested that false-belief understanding and language ability jointly and fully mediated the effect of preschoolers' EC on their prosocial orientation. Analysis of covariates revealed that gender exerted no statistically significant effect, while age had a trivial positive effect. Theoretical and practical implications of the findings are discussed.
