Resumen:
How children learn to form supra-ordinate categories: A training study This research investigates how children learn to categorize familiar objects in supra-ordinate categories. As a base-line, Experiment 1 showed that 6-years-olds were able to form supra-ordinate categories, whereas 3-years-olds were not. Then, a pretest-posttest training study (Experiment 2) assessed whether 3-years-olds´s failures in categorization at higher-order levels could be turn into successful categorization within a child-adult collaborative context. This training study compared the performance of 3-year-olds in three conditions: no-instruction, comparison and conceptual-based conditions. As predicted, only the groups who received instruction about the objects to be compared (comparison instruction) or the properties to be inferred (conceptual-based instruction) arrived at a satisfactory categorization in the posttest. The results raise two issues about the status of social interaction in category development: a) instruction as a precondition for developmental changes and, b) the dependence on social interactions as a possible explanation of why higher-order categories are acquired rather later in development.
