Experimental investigations were carried out whether we can recognize the facial identity between a child and an adult face; although an adult face was structurally change from a child face through growth. The main findings of this research were as follows.
(1) The results of all experiments showed the rated facial identity of same person's pairs were significantly higher than one of different person's pairs. This finding suggests we can recognize the facial identity between a child and an adult face, although the structure of face is changed through growth.
(2) When the participants were familiar with the stimulus adult faces, the performance of the recognition of facial identity was significantly improved.
(3) When the several different poses of stimulus face were presented to the participants prior to the rating experiment of facial identity, the performance of the recognition of facial identity was significantly improved. But the performance was not improved, when the same pose of stimulus face was presented to the participants.
(4) The verbal reports of cues of judgments were showed the region of nose was relatively high salient for the recognition of facial identity.
(5) Any clear conclusion could not deduce about the influence of rated distinctiveness of face to the recognition of facial identity between a child and an adult face.
(6) When the stimulus faces were presented upside-down, the performance of the recognition for different person's pairs was significantly declined. But the performance of the recognition for same person's pairs was not changed.
