We investigated the role of distinct inhibitory processes as 4- to 6-year-olds from the Northeastern United States (N = 48, M[subscript age] = 68.27 months, 22 boys, 26 girls; 63% White, 6% Black, 4% Asian, 2% Hispanic, 8% more than one race, with 17% not reporting) and adults evaluated accurate or deceptive information from human or non-human…

Children hold rich essentialist beliefs about natural and social categories, representing them as discrete (mutually exclusive with sharp boundaries) and stable (with membership remaining constant over an individual's lifespan). Children use essential categories to make inductive inferences about individuals. How do children determine what…

Although action experience has been shown to enhance the development of spatial cognition, the mechanism underlying the effects of action is still unclear. The present research examined the role of visual cues generated during action in promoting infants' mental rotation. We sought to clarify the underlying mechanism by decoupling different…

In simple rule-switching tests, 3- and 4-year-olds can follow each of two sorting rules but sometimes make perseverative errors when switching. Older children make few errors but respond slowly when switching. These age-related changes might reflect the maturation of executive functions (e.g., inhibition). However, they might also reflect…

Contrast information could be useful for verb learning, but few studies have examined children's ability to use this type of information. Contrast may be useful when children are told explicitly that different verbs apply, or when they hear two different verbs in a single context. Three studies examine children's attention to different types of…

By preschool age, children have a sophisticated assumption about the conventional nature of various kinds of information. The present studies investigated the role of two cues in 2- and 3-year-olds' determination of what is conventional, namely the intentionality and intra-individual consistency in the use of objects. Overall, in Study 1, both 2-…

In this study the authors examined children's ability to code visual information into an egocentric frame of reference for planning reach movements. Children and adults estimated reach distance via motor imagery in immediate and response-delay conditions. Actual maximum reach was compared to estimates in multiple locations in peripersonal and…

The present study examined whether younger and older children differ in the use of the goal-related information in a continuous performance task (AX-CPT), and if so, whether those age differences are due to the ability to represent and/or maintain goal information. Experiment 1 compared third- and sixth-grade children in their ability to transform…

Two-year-olds' appreciation of the shared nature of object labels versus object preferences was examined in 2 studies. A total of 128 24- to 27-month-olds played a finding game with an experimenter during which they were taught a piece of information about a target object in a nonostensive learning context. In Experiment 1, children were presented…

Seven-year-olds completed a Posner cued attention task, under both neutral and affectively charged conditions. Compared to the traditional (affect-neutral) Posner task, performance in the affective Posner task was marked by dramatic decreases in reaction times (RTs), an increase in errors, an increased validity effect (difference in RTs to the…
