Developmental Changes in the Induction of Semantic Relations.
Lairon, Mary A.; And Others
Relational-inference, a process associated with developmental change in performance on classification items, was investigated in two experiments. The accuracy and latency with which 20 subjects at each of 3 age levels (8, 11, and adult) stated relationships among concepts were tested. In experiment 1, 40 triplets of concepts related by a class rule and 40 by a property rule were presented. Eight-year-olds were slower and less accurate than the 11-year-olds and adults, especially on property rule items. Experiment 2 explored semantic memory search processes in more detail by examining the hypothesis that the inference process would be negatively affected if an initial inference for a pair of terms had to be revised when a third term was added. Items reflecting five types of class and property rule combinations were examined. Revision items required more time than nonrevision at all age levels. Accuracy varied across ages and type of rule revision. When similar nodes and links exist, developmental differences are associated with the efficiency of activation and retrieval processes, with the effects of path activation on the subsequent activation of competing paths, and with changes in the contents of the network.
