Early puzzle play: A predictor of preschoolers' spatial transformation skill.

Early puzzle play: a predictor of preschoolers' spatial transformation skill.

Individual differences in spatial skill emerge prior to kindergarten entry. However, little is known about the early experiences that may contribute to these differences. The current study examined the relation between children's early puzzle play and their spatial skill. Children and parents (n = 53) were observed at home for 90 min every 4 months (6 times) between 2 and 4 years of age (26 to ...

Developmental Psychology Early Puzzle Play: A Predictor of Preschoolers' Spatial Transformation Skill

Early sex differences in spatial skill.

This study investigated sex differences in young children's spatial skill. The authors developed a spatial transformation task, which showed a substantial male advantage by age 4 years 6 months. The size of this advantage was no more robust for rotation items than for translation items. This finding contrasts with studies of older children and adults, which report that sex differences are large...

An important question is the degree to which past exploration and learning experiences affect exploration in novel contexts. In particular, children often get information about the difficulty of a completed task (“that was hard!”), but we do not...
