Prior research suggests that preschoolers can generalize object properties based on category information conveyed by semantically-similar labels. However, previous research did not control for co-occurrence probability of labels in natural speech. The current studies re-assessed children's generalization with semantically-similar labels.…

Rule-based and information-integration category learning were compared under minimal and full feedback conditions. Rule-based category structures are those for which the optimal rule is verbalizable. Information-integration category structures are those for which the optimal rule is not verbalizable. With minimal feedback subjects are told whether…

Children aged 6 to l7 were taught novel class inclusion hierarchies, analogous to the relation among oaks, pines, and trees. The results indicated that the part-whole structure of collections is simpler to establish and maintain than the structure of inclusion. (Author/RL)
