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…

It has been debated whether the progressive emergence of theory of mind (ToM) in autistic children is compatible with a "delayed" or "different" development model, and whether and how the sequential consolidation of ToM concepts is subject to cross-cultural variations in autistic and typically developing (TD) children. To study…

Number line estimation (NLE) tasks are widely used to investigate numerical cognition, learning, and development, and as an instructional tool. Interpretation of these tasks generally involves an implicit expectation that responses are driven by the overall magnitudes of target numerals, in the sense that the particular digits conveying those…

Problem solving is an important cognitive skill that children use to plan and navigate various developmental and social tasks. Although previous research was theory-grounded and systematic, to our knowledge, no research has observed and documented children's problem solving as a primary objective in naturalistic developmental contexts, such as…

The recent proliferation of research on children's supernatural concepts is noteworthy, as this work is necessary for a full account of human cognition. Despite this advancement in our field, there is a lingering tendency for scholars to exotify supernatural concepts; to treat them as distinct or special. Arguments have been raised that these…

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…

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.…

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…

Data from a large-scale, longitudinal research study with an ethnically and socioeconomically diverse sample were utilized to explore linkages between maternal elaborative conversational style and the development of children's autobiographical and deliberate memory. Assessments were made when the children were aged 3, 5, and 6 years old, and the…

Young children can engage in diagnostic reasoning. However, almost all research demonstrating such capacities has investigated children's inferences when the individual efficacy of each candidate cause is known. Here we show that there is development between ages five and seven in children's ability to reason about the number of candidate causes…

Young children tend to judge improbable events to be impossible, yet there is variability across age and across individuals. Our study examined parent-child conversations about impossible and improbable events and links between parents' explanations about those events and children's possibility judgments in a reasoning task. Regression analyses…

What is the developmental course of children's gender constancy? Do other cognitive abilities such as time comprehension and false-belief understanding foster gender constancy and the subcomponents gender stability and gender consistency? We examined the development of gender constancy and its relation to time comprehension and false-belief…

Recent studies have established that even infants can determine what others know based on previous visual experience. In the current study, we investigated whether 2-and 3-year-olds know what others know based on previous auditory experience. A child and an adult heard the sound of one object together, but only the child heard the sound of another…

A problematic issue for forensic interviewers is that young children provide limited information in response to open-ended recall questions. Although quantity of information is greater if children are asked more focused prompts and closed question types such as yes/no or forced choice questions, the quality of their responses is potentially…
