表情図分類行動における発達的特性

抄録

Children, at age of 3, 4, 5, 6 and 8, were asked to classify the pictures of facial expressions showing three emotional expressions into whichever categories they liked (“free condition”), and to classify them into three categories (“restricted condition”). The results showed that most of children (3 and 5 year old) classified the pictures into non-emotional categories. Many children (6 and 8 year old) classified them into emotional categories. Classification accuracy in “free condition” was higher than that of “restricted condition”. In the second experiment, subjects were asked to classify the pictures of non-facial expression into whichever categories they liked, and then to classify the facial expression-pictures into whichever categories they liked. The results showed similar trends to the results of “free condition”.
