Young children category learning: A training study

From an integrative approach, this work focuses on the role of conceptual mechanisms, such as comparison and conceptual-based inference, and sociopragmatic support in young children's taxonomic categorization. "Experiment 1" assessed whether 3- , 4-, and 6-year-old children succeed in detecting taxonomic relations on their own. A clear developmental trend was found: 6-year-olds succeeded, whereas 4- and 3-year-olds relied primarily on perceptually based categories. "Experiment 2" assessed if 3-year-olds are able to change their perceptual response into a taxonomic categorization as a function of the cooccurrence of contingent category information and feedback in an interactive process with an adult (experimenter). A pretest-posttest training study compared 3-year-olds' performance in four conditions: comparison, conceptual-based, information-only, and feedbackonly. A perceptual-totaxonomic shift was found only in the comparison and conceptualbased training groups. Children who only received either category information or corrective feedback did not make such a shift. The results show that social interaction with supportive adults is a mechanism that drives conceptual understanding in early childhood. Fil: Taverna, Andrea Sabrina.
