The purpose of this study was to clarify the developmental process of joint visual attention and response to pointing in infants from 3 to 8 months old. In experiment I, target object was not set up, and in experiment II, target object was set up in the direction of experimenter's regard or pointing. The results obtained from experiment I were as follows; (1) joint visual attention was found in 3 months, and (2) regarding the direction of pointing was hardly found in all months. The results obtained from experiment II were different from those of experiment I; (1) regarding the direction of pointing was found in 3 months, while (2) regarding the pointing of finger was not found. These results indicated that joint visual attention was brought about from 3 months, and responses to pointing was closely related to existence of target object.
