The purpose of this study was to investigate the retrieval speed of mental retardates in a constrained recall task. Eighteen retardates(Mean CA=17:10, Mean MA=9:1, Mean IQ=51)and eighteen equal MA non-retardates(Mean CA=9:3, Mean MA=9:11, Mean IQ=108)were asked to learn a list of twelve pictures from three taxonomic categories. After all pictures were presented in category block subjects were required to recall them in a constrained method. Dependent variables were as follows:(1)Numbers of recalled items within categories;(2)RT, the time interval between experimenter's category instraction and subjects' first recall response;(3)WCI, the time interval between a recall response and the next one. The main results were: RT of retardates was longer than that of nonretardates; also, WCI showed similar results. Such results suggested that one of the cognitive deficits of retardates was in the difficulty of category access.
