Recent research has highlighted the critical role in children's cognitive development of the metacognitive support parents give their children during everyday interactions. Our main goal was to examine whether parents made consistent use of metacognitive talk across different parent - child interaction contexts and to document the effect of this…

Children are limited in visual search accuracy and this ability increases from childhood to adolescence. Developmental limitations in visual search could be related to children's difficulties in efficiently planning and executing their search, often assessed with cancellation tasks. However, few studies have examined age-related changes in visual…

For decades, developmental psychologists and educators have emphasized that learning about counterintuitive phenomena may be a critical driving force for cognitive development. Thus far, little is known about the specific content that children seek to enrich their knowledge. Using a novel book-choice paradigm, we directly examine children's…

The majority of the world's children live in low- and middle-income countries, yet the majority of early childhood cognitive research is done with a small proportion of high-income countries. These findings cannot be assumed to apply across all contexts. It is therefore necessary to confront entrenched systems of power and privilege in early…

Previous research has demonstrated a link between children's ability to name canonical finger configurations and their mathematical abilities. This study aimed to investigate the nature of this association, specifically exploring whether the relationship is skill and handshape specific and identifying the underlying mechanisms involved.…

Recent research has shown that from early in development, children selectively form new beliefs in response to information supplied by others. However, little is known about the development of selective revision of existing beliefs in response to socially conveyed information. Such selective social belief revision has been extensively studied by…

This article serves as an introduction to the Special Issue on "Decolonizing and Diversifying Research in Cognitive Development." The Special Issue comprises six articles: two articles are empirical articles that focus on executive function development in under-represented environments, two articles address barriers pathways toward…

It has been suggested that due to functional similarity, sortal object individuation might be a primordial form of psychological essentialism. For example, the relative independence of identity judgment from perceived surface features is a characteristic of essentialist reasoning. Also, infants engaging in sortal object individuation pay more…

It has been argued that the distinction between factivity and non-factivity is more fundamental to mental state understanding than that between false beliefs and reality. The present study examined children's growing understanding of all possible contrasts between the factive verb "know" and the non-factive verbs "think" and…

Evidence points to the possibility of promoting executive functions (EF) through school interventions. Little is known, however, about the effectiveness of this type of intervention in situations of social vulnerability. This study investigated the effectiveness of an EF intervention program applied with a sample of preschool children, in a…

An increasing number of findings suggest that cognition is grounded in sensorimotor experiences. Research suggests that fine motor skills (FMS) link to cognitive abilities. Existing studies, however, lack conceptual and methodological differentiation regarding FMS and little is known about the directional nature of links. In study 1, we measured…

The acquisition of theory of mind (ToM) -- the ability to attribute mental states to explain others' behaviors -- is a critical milestone in children's cognitive development. Previous research has established that deaf children experience significant delays in ToM compared to hearing children within the same culture. However, prior studies were…

This study examined how 5- and 9-year-old children (N = 40) produce pantomimes of object use on verbal request. The task required participants to enact an action with an imagined object. Results showed that with age, children (a) proceeded from body part as object to imaginary object and (b) incorporated into their pantomimes more distinctive…

There are socioeconomic-status (SES) differences in cognitive development. Various factors have been proposed that might explain this association, and one of these factors is the home environment. The present study examined a chaotic home atmosphere as a potential mediator of the association between parental SES and cognitive development. A…

There is now wide consensus that the quality of family relationships is involved in the development of child executive functioning (EF), a set of cognitive skills that bear critical importance for social and academic adjustment at school. This body of research has, however, focused almost exclusively on dyadic parent-child interactions and failed…
