Studies with preschool children have shown significant links between children's executive function (EF) and theory of mind (ToM), but few studies have examined these associations in primary school children. To address this gap, we designed a three-wave cross-lagged longitudinal study in which we followed a group of 113 children (61 boys) across three time points from age 9.5-10.5years (mean age at Time 1=112.3months, SD=4.18; mean age at Time 2=118.3months, SD=4.15; mean age at Time 3=124.7months, SD=4.06). At each time point, we measured EF (working memory and inhibitory control), ToM, and language. Our analyses showed (a) moderate rank-order stability of individual differences in both EF and ToM and (b) growth in ToM task performance across time. Cross-lagged longitudinal analyses revealed an asymmetric developmental relation between ToM and working memory. Early working memory predicted later ToM but not vice versa. Our results suggest a specific role for working memory in the ongoing development of ToM in middle childhood.

Despite 30years of productive research on theory of mind (ToM), we still know relatively little about variables that influence ToM development during middle childhood. Recent experimental studies have shown that conversations about the mind affect ToM abilities, but they have not explored the mechanisms underlying this developmental effect. In the current study, we examined two potential mechanisms through which conversations about mental states are likely to influence ToM: an increased frequency of references to mental states when explaining behavior and an increased accuracy of mental-state attributions. To this aim, we conducted a training study in which 101 children were assigned to either an intervention condition or a control condition. The conversation-based intervention was made up of four sessions scheduled over 2weeks. Children completed a battery of assessments before and after the intervention as well as 2months later. The groups were equivalent at Time 1 (T1) for age, family affluence, vocabulary, and executive functions. The ToM group showed an improvement in ToM skills (as evaluated on both the practiced tasks and a transfer task). Mediation analyses demonstrated that the accuracy of mental-state attributions, but not the mere frequency of mental-state references, mediated the positive effect of conversations about the mind on ToM development. Our results indicate that conversational experience can enhance mental-state reasoning not by simply drawing children's attention to mental states but rather by scaffolding a mature understanding of social situations.

Objectives: Previous research has shown that individual differences in Theory of Mind (ToM) are crucial for people's social relationships. However, very few studies have investigated this issue in ageing. The present study was designed to fill this gap and examine the associations between ToM and social relationships in elderly adults. In doing so, this study considered people's relationships with their relatives and friends, and examined the possible moderating role of social motivation. Method: The study involved 53 healthy older adults (age: M = 67.91; SD = 6.93; range: 60--85 years). All participants were tested collectively during a 2-hr session and completed a demographic questionnaire as well as a battery of tests assessing verbal ability (vocabulary and word fluency), ToM and social relationships. They also answered a social motivation question. Results: Results showed that individual differences in older people's ToM were overall significantly associated with those in relationships with friends, but not relatives. In addition, the Hayes moderating procedure showed that individual differences in ToM were related to those in friendships only for those people who had a high or medium level of social motivation. Conclusion: These findings underline the importance of motivation in guiding the use of ToM in everyday social interactions.

Background: When COVID-19 was declared as a pandemic, many countries imposed severe lockdowns that changed families’ routines and negatively impacted on parents’ and children’s mental health. Several studies on families with children with autism spectrum disorder (ASD) revealed that lockdown increased the difficulties faced by individuals with ASD, as well as parental distress. No studies have analyzed the interplay between parental distress, children’s emotional responses, and adaptive behaviors in children with ASD considering the period of the mandatory lockdown. Furthermore, we compared families with children on the spectrum and families with typically developing (TD) children in terms of their distress, children’s emotional responses, and behavioral adaptation. Methods: In this study, 120 parents of children aged 5–10 years (53 with ASD) participated. Results: In the four tested models, children’s positive and negative emotional responses mediated the impact of parental distress on children’s playing activities. In the ASD group, parents reported that their children expressed more positive emotions, but fewer playing activities, than TD children. Families with children on the spectrum reported greater behavioral problems during the lockdown and more parental distress. Conclusions: Our findings inform the interventions designed for parents to reduce distress and to develop coping strategies to better manage the caregiver–child relationship.
