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…

When reasoning about a representation (e.g., a toy lion), children often engage in "iconic realism," whereby representations are reported to have properties of their real-life referents. The present studies examined an inverse difficulty that we dub "representational disregard": overlooking (i.e., disregarding) a…

The Wechsler Preschool and Primary Scale of Intelligence, 4th ed. includes two measures of working memory normed on children 2;6-7;7. The present analyses of the typically developing children (N = 1,591, 812 female, 779 male, with an ethnic distribution approximating the United States) provide new, theoretically important information about these…

This study examined children's emotion attributions and moral judgements to hypothetical procedural justice outcomes when the candidates were equal in merit but different in need. Children (7 to 11 years old, N = 88) were presented with four vignettes depicting resource-rich and resource-poor candidates losing educational materials and…

Various forms of humor are an important aspect of social interactions, even at an early age. Humor comprehension is a repertoire that is said to emerge between the ages of 7 and 11 years, and this is primarily attributed to a child's level of cognitive development. The behavioral literature has suggested that various forms of complex verbal…

PlayWisely is a novel approach to early learning designed to target the positive development of a wide range of cognitive and physical/motor abilities by stimulating the rapidly developing brain of very young children (from 4 months to 3 years of age). The current pilot study represents a first step toward providing an evidence base for the…

Background: Dialogic reading (DR; Whitehurst et al., 1988) is an evidence-based intervention that promotes children's active participation in shared reading (Towson, 2016; Urbani, 2020; WWC, 2007, 2010). Since the development of DR, there has been a proliferation of studies evaluating the conditions and populations with which it is effective.…

Teachers often see repetitive behaviors in toddler and preschool classrooms, such as building and knocking down block towers or dumping out toys. When children do these actions over and over it can be frustrating to teachers and parents, but viewing these actions through the lens of schema theory helps us understand what's really going on in…

The socioeconomic attainment gap in mathematics starts early and increases over time. This study aimed to examine why this gap exists. Four-year-olds from diverse backgrounds were randomly allocated to a brief intervention designed to improve executive functions (N = 87) or to an active control group (N = 88). The study was preregistered and…

When do children acquire a meta-representational Theory of Mind? False Belief (FB) tasks have become the litmus test to answer this question. In such tasks, subjects must ascribe a non-veridical belief to another agent and predict/explain her actions accordingly. Empirically, children pass explicit verbal versions of FB tasks from around age 4.…

This study assessed children's (N = 236) ability to introspect the mental states of "seeing" and "knowing" relative to their ability to attribute each state to others. Children could introspect "seeing" 10 months before they could introspect "knowing." Two- and 3-year-olds correctly reported their own…

The emerging field of robotics education (RE) is a new and rapidly growing subject area worldwide. It may provide a playful and novel learning environment for children to engage with all aspects of science, technology, engineering, and mathematics (STEM) learning. The purpose of this research is to examine how robotics learning activities may…

This study proposes a family psychobiosocial model on gender differences in cognitive development. Specifically, the aim is to investigate how family biological, socioeconomic, and psychological factors predict child mathematics achievement (MAch) development. The data were obtained from the Millennium Cohort Study. Children's pattern construction…

Identifying and describing children's play behaviours is an important component of evaluating child development. The Behaviour Mapping Schedule is a direct observational tool which aims to describe and quantify children's play behaviours but is yet to undergo reliability testing. This study aimed to determine the intra- and inter-rater reliability…

Mutualism is a developmental theory that posits positive reciprocal relationships between distinct cognitive abilities during development. It predicts that abilities such as language and reasoning will influence each other's rates of growth. This may explain why children with Language Disorders also tend to have lower than average non-verbal…
