This study examined whether executive functions impact how flexibly children represent task context in performing repeated sequential actions. Japanese children in Experiments 1 (N = 52; 3-6 years) and 2 (N = 50, 4-6 years) performed sequential actions repeatedly; one group received reminders. Experiment 1 indicated that reminders promote flexible…

Previous research has shown that children aged 4-5 years, but not 2-3 years, show adult-like interference from a partner when performing a joint task (Milward, Kita, & Apperly, 2014). This raises questions about the cognitive skills involved in the development of such "corepresentation (CR)" of a partner (Sebanz, Knoblich, &…

In this study of two hundred and thirty 8- to 13-year-olds, a new "Silent Films" task is introduced, designed to address the dearth of research on theory of mind in older children by providing a film-based analogue of F. G. E. Happe's (1994) Strange Stories task. Confirmatory factor analysis showed that all items from both tasks loaded…

Adolescents' beliefs about the legitimacy of parental authority and obligation to obey were examined in 568 Chilean adolescents (11-14 years old at Wave 1), followed once a year for 4 years. Adolescents' beliefs about parental legitimacy and obligation to obey declined with age. The steepest decline occurred during early adolescence, particularly…

Using a genetic design of 840 60-month-old twins, this study investigated the genetic and environmental contributions to (a) individual differences in four components of cognitive school readiness, (b) the general ability underlying these four components, and (c) the predictive association between school readiness and school achievement. Results…

Imitation, vocabulary, pretend play, and socially insightful behavior were investigated in 5,206 same- and opposite-sex 2-year-old twin pairs in the United Kingdom. Individual differences in imitative ability were due to modest heritability (30%), while environmental factors shared between twins (42%) and unique to each twin (28%) also made…

Assessed preschoolers' moral motive strength or attribution of moral emotions to story characters. Also assessed temperamental inhibition and self-control. Children were provided with an opportunity to cheat when they felt they were unobserved. Results indicated that moral motive strength and inhibition predicted low cheating. (BC)

Among 120 fourth and sixth graders, correlations between intelligence scores and agency beliefs for effort decreased with increasing levels of reasoning about effort and ability. Correlations between intelligence scores and agency beliefs for ability increased with increasing levels of reasoning. (RH)

Examined relations of individual differences in regulation and negative emotionality to Indonesian third-graders' social skills/low externalizing problem behavior, sociometric status, and shyness. Found that children's low socially appropriate behavior/high problem behavior and rejected peer status were related to low dispositional regulation and…

Accuracy-disabled and rate-disabled young Canadian readers were compared to children who were "fluent normal" readers. Children in the latter group decoded at the same level of accuracy as the rate-disabled subjects but at a significantly faster rate. Specific deficiencies of each of the disabled groups were identified. (Author/RH)

Compared the attachment classification distributions of 23 infants in Israeli kibbutzim with communal sleeping arrangements with those of 25 infants in kibbutzim with home-based sleeping arrangements. Among the home-based infants, 80% were securely attached to their mothers versus only 48% of the infants in communal sleeping arrangements. (MDM)

Examined continuity in parent-child relationships in a sample of German families. Traced connections between individual differences in a composite of markers of the parent-child attachment relationship system and later parent-child communications. Found that the composite modestly predicted variability in children's competence in forming…

Evaluated effects on children in Bosnia and Herzegovina of a 5-month psychosocial intervention program of weekly group meetings for mothers. Found that although all participants were exposed to severe trauma, their distress varied considerably. The intervention program had a positive effect on mothers' mental health, children's weight gain, and…

This study examined demographic and individual difference variables that predicted level of Brazilian adolescents' prosocial moral judgment and self-reported prosocial behavior; it also tested mediating or moderating relations among predictors. Findings generally were consistent with contention that tendency to take others' perspectives and to…
