The effects of task comprehension on preschoolers' and adults' categorization choices

Article Abstract:

Preschoolers' tendency to sort objects according to appearance or taxonomic relations is strongly affected by instructions and training. Adults' categorization preferences are affected by instructions, but not by training. Preschoolers have a flexibility in their sorting decisions; in most cases, pre-schoolers use the most salient feature of the objects to categorize according to either appearance or taxonomic relations.

Perceived reachability for self and for others by 3-to-5-year-old children and adults

Article Abstract:

Assessment of the ability of three-, four-, five-year-olds and adults to perceive reachability of objects validated the hypothesis that spatial decentration and perspective taking are task specific and occur early in life. Children resemble adults in their display of allocentrism in their judgments about reachability pertaining to perceptual tasks.
