構成行為における探索活動の役割とその獲得過程

抄録

This study examined the role of searching function in constructional activity and the process of getting it. One hundred infants (from three years and four months to six years and eleven months) and 10 adults were asked to construct a human face by arranging 8 parts under blindfold conditions (Experiment I). The result showed that the constructional outcome was related to searching state, though in infants who failed the task, such searching state was found to be inactive or nonsystematic. However in many cases subjects were able to search in a task that searching target was specified by the task itself (Experiment II). So when subjects constructed a human face again, the experimenter gave them verbal instructions asking to search and point out searching target (Experiment III). Through these instructions, their searching became more active and systematic and most of their constructions improved. It was suggested that searching function in constructional activity would be acquired when the inner image as a model of construction was connected with searching plans including such verbal regulating functions as given through instructions.
