Attentional theories of associative learning and categorization propose that learning about the predictiveness of a stimulus influences the amount of attention that is paid to that stimulus. Three experiments tested this idea by looking at the extent to which stimuli that had previously been experienced as predictive or nonpredictive in a…

Many theories of category learning assume that learning is driven by a need to minimize classification error. When there is no classification error, therefore, learning of individual features should be negligible. The authors tested this hypothesis by conducting three category-learning experiments adapted from an associative learning blocking…

Implicitly repeating categories by presenting words not present in the original categorized list but logically members of previously studied categories significantly increased acquisition and retention relative to repeating category labels, repeating members of categories, and repeating neither labels nor members. The efficiency of repetition…

Contrary to the basic-level restraint hypothesis, which suggests that young children learn basic-level words more easily than specific-level words, these five studies show that although other constraints on word meaning may be in place, children are flexible in interpreting new words at different hierarchical levels.
