The present study tested the hypothesis that verbal labels support category induction by providing compact hypotheses. Ninety-seven 4- to 6-year-old children (M = 63.2 months; 46 female, 51 male; 77% White, 8% more than one race, 4% Asian, and 3% Black; tested 2018) and 90 adults (M = 20.1 years; 70 female, 20 male) in the Midwestern United States…

Children perform worse than adults on tests of cognitive flexibility, which is a component of executive function. To assess what aspects of a cognitive flexibility task (cued switching) children have difficulty with, investigators tested where eye gaze diverged over age. Eye-tracking was used as a proxy for attention during the preparatory period…

When and how do infants learn color words? It is generally supposed that color words are learned late and with a great deal of difficulty. By examining infant language surveys in British English and 11 other languages, this study shows that color word learning occurs earlier than has been previously suggested and that the order of acquisition of…

Four studies explored the abilities of 80 adults and 180 children (4-9 years), from predominantly middle-class families in the Northeastern United States, to use information about machines' observable functional capacities to infer their internal, "hidden" mechanistic complexity. Children as young as 4 and 5 years old used machines'…

Children ages 6 to 13 and college students were asked to remember length relationships for three pairs of sticks. For six- and seven-year-olds, relationships between interlinked pairs were much more difficult to retain than were relationships between unrelated pairs. (Author/MP)

Describes two studies which tested the hypothesis that short simple sentences addressed to children are the result of children signaling non-comprehension for longer, complex utterances. (JMB)

The purpose of this research was to examine developmental changes in the knowledge about what variables affect performance on the incidental learning task. Kindergarteners, second graders, fifth graders, and college students indicated on a rating scale how many animals a hypothetical person would remember under easy and difficult levels of each…
