[Effects of bodily movement and verbal information on memory for action events].

The purpose of this study was to examine effects of bodily movement and verbal information on memory representation of an action. Whether the subject actually performed the action (SPTs) or he/she saw the experimenter do (EPTs) was bodily movement factor. Whether a verbal description of the sequence was given or not was verbal information factor. The two factors formed four groups in Experiment 1, and 56 subjects participated, using two kinds of memory material as a third factor: instruments and bodily movement. Supplemental analyses were the purpose of Experiment 2, in which 112 subjects in eight groups participated, examining verbal or motor recall and recognition. Results of the two experiments suggested that bodily movement facilitated integration of verbal and motor-action components when verbal information was also present. In addition, it was suggested that bodily movement helped form 'motor imagery' as memory representation, which was utilized at generation stage of memory retrieval and verifying stage of motor recognition. With these results, the relationship between processing of verbal component and that of motor-action component was discussed.
