Gender-stereotyped beliefs develop early in childhood and are thought to increase with age based on prior research that was primarily carried out in Western cultures. Little research, however, has examined cross-cultural (in)consistencies in the developmental trajectory of gender-stereotyped beliefs. The present study examined implicit gender-toy…

The purpose of this study is to investigate how young children define trust and to find out if there is a relationship between the people whom they trust and the people with whom they share their favorite food and toy. The participants consist of 273 kindergarteners enrolled in five public kindergartens. Research assistants asked the participants…

Pretend play is important for children's development. However, recent research indicates that, as preschool children age and get more proficient at pretend play, they prefer real objects. We examined whether toddlers prefer real objects when they are younger as well as when they are older and more proficient in pretend play situations. Forty-three…

We tested 6- and 8-month-old White and non-White infants (N = 53 total, 28 girls) from Northern California in a visual search task to determine whether a unique item in an otherwise homogeneous display (a singleton) attracts attention because it is a unique singleton and "pops out" in a categorical manner, or whether attention instead…

Verbal testimony about reality status is critical but often contradictory. These studies address whom children consider reliable sources of information about reality and how they evaluate conflicting testimony. In Study 1, seventy 4- to 8-year-olds heard an adult or child provide testimony about how to cook food and use toys, and about the reality…

Children's block building has long been a focus of psychological research, in part because block building skills are thought to be useful indicators of other abilities such as representational thinking. Block building skills are assumed to progress through developmental stages and a number of measures have been developed to assess these skills. In…

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 presented with a claim that contradicts their intuitions, do children seize opportunities to empirically verify such claims or do they simply acquiesce to what they have been told? To answer this question, we conducted a replication of Ronfard et al. (conducted in the People's Republic of China) in two countries with distinct religious and…

This study investigated the role of children's gender stereotypes and peer playmate experiences in shaping their desire to play with peers who hold counterstereotypical preferences (e.g., a boy who likes dolls or a girl who likes trucks). Children (N = 95; 46 girls, 49 boys; 67% White, 18% Black, 8% Latinx, 4% Asian, 3% other; median household…

Engaging, focusing, and persisting in the completion of tasks are among the skills needed for school success. Tracking whether a child is learning cognitive problem-solving skills is essential in knowing if they are acquiring skills important for development and school readiness; and if not, how they are responding to early intervention. Use of…

The present studies (N = 159) investigated children's and adults' preferences for label and property conjunctions for cross-classifiable toys. In Study 1, 4-year-olds, 5-year-olds, and adults participated in a labelling and property attribution task involving experimental toys that belong to two categories and control toys that belong to only one…

In early childhood, young children frequently engage in object-oriented play. According to cultural-historical activity theory, object-oriented play provides children with opportunities to learn about the characteristics and cultural applications of objects and materials. These characteristics are referred to as rules or affordances of objects and…

We aimed to longitudinally examine how symbolic distancing affects preschool children's delay tolerance in a delay choice task. We presented children with choices between a smaller immediate reward and a larger delayed reward in conditions with either symbolic stimuli or edible rewards. Overall, symbolic distancing modulated children's delay…

This study examined play interactions of 15 to 48-month-old children (n = 59) and their caregivers in Lazuri, a UNESCO-rated endangered South-Caucasian ancestral language, and Turkish, a dominant language supplanting Lazuri usage in the community. Child-caregiver dyads played with two toy sets (animal farm and tea set) that provided different…

Background: Pretend play is a form of play that involves nonliteral actions. There are limited studies reporting the developmental trends of pretend play behaviours of typically developing pre-schoolers. This knowledge would be beneficial in the early identification of deviations in pre-schoolers who have or are at risk of developing developmental…
