Working memory training improves children's cognitive performance on untrained tasks; however, little is known about the underlying neural mechanisms. This was investigated in 32 typically developing children aged 10-14 years (19 girls and 13 boys) using a randomized controlled design and multi-modal magnetic resonance imaging (Devon, UK;…

The success of human culture depends on early emerging mechanisms of social learning, which include the ability to acquire opaque cultural knowledge through faithful imitation, as well as the ability to advance culture through flexible discovery of new means to goal attainment. This study explores whether this mixture of faithful imitation and…

Relational reasoning is a hallmark of human higher cognition and creativity, yet it is notoriously difficult to encourage in abstract tasks, even in adults. Generally, young children initially focus more on objects, but with age become more focused on relations. While prerequisite knowledge and cognitive resource maturation partially explains this…

Guided by evolutionary-developmental models, this study tested the hypothesis that children's exposure to parental relationship instability, defined by initiation and dissolution of caregiver intimate relationships, has both costs in cognitive impairments and benefits in enhanced learning skills. Participants included 243 mothers and their…

Previous and current research identify Metalinguistic Awareness (MLA) as a possible cause of the positive effects of bilingualism on cognitive development and Third Language Acquisition (TLA). Although it has been acknowledged that MLA is strongly affected by literacy and grammar-related activities, only a few studies have focused on the context…

This paper investigated how production task combined with teacher feedback (in the form of recasts) affects child second language development, and the effects of task complexity on their production performance. 92 child learners of English in three intact classes were assigned to three tasks of different complexity (simple, +complex, ++complex).…

Over the last 2 centuries there has been a rapid increase in the proportion of children who grow up in cities. However, relatively little work has explored in detail the physiological and cognitive pathways through which city life may affect early development. To assess this, we observed a cohort of infants growing up in diverse settings across…

Two studies are presented to examine whether and why 3-5-year-olds in Pakistan display limited social understanding. Study 1 tested 71 preschoolers on Lillard and Flavell's (1992) test of desires, pretence and beliefs, plus two false belief tasks, and showed very limited understanding across these measures even though almost half were over 5 years…

Remembering to carry out intended actions in the future, known as prospective memory (PM), is an important cognitive ability. In daily life, individuals remember to perform future tasks that might rely on effortful processes (monitoring) but also habitual tasks that might rely on more automatic processes. The development of PM across childhood in…

Children start preschool with large individual differences in their early numerical abilities. Little is known about the importance of heterogeneous patterns that exist within these individual differences. A person-centered analytic approach might be helpful to unravel these patterns and the cognitive and environmental factors that are associated…

Extensive research has demonstrated the impact of working memory (WM) on first language (L1) reading comprehension across age groups (Peng et al., 2018), and on foreign language (FL) reading comprehension of adults and older adolescents (Linck et al., 2014). Comparatively little is known about the effect of WM on young FL readers' comprehension,…

To explore the potential contribution of parents' causal talk to preschooler's emerging scientific literacy and related interests, we observed 153 parent-child dyads playing together in a museum and in the lab. As in previous work, the frequency with which parents referenced causal information in their speech predicted the strength of their…

This study investigated the prospective relationship between preschoolers' theory of mind (ToM) skills and academic school readiness, while exploring the possible moderator role played by child gender. The participants were 75 children who were assessed at two time points: when enrolled in the second preschool year (T1) and again 4 months before…

Improvements in cognitive flexibility during the preschool years have been linked to developments in both working memory and inhibitory control, though the precise contribution of each remains unclear. In the current study, one hundred and twenty 2-, 3-, and 4-year-olds completed two rule-switching tasks. In one version, children switched rules in…
