We investigated the effect of face inversion by using both upright and inverted stimuli which were the pictures of three familiar people from five different views (from the frontal face to the back of the head in steps of 45°). Two identification tasks were managed before and after the inverted adaptation task. As results, the effect of face inversion was shown in the 3/4 views of face and the profile before the inverted adaptation task. However, this effect was not shown after the inverted adaptation task in all head angles. The mean reaction time was not affected with the inverted head angle changes. These results suggested that the familiarity of the frontal face and the information of three dimensions relating to the face also might be the factors of the effect of face inversion. Main factor was supposed to be different in the changing head angles.
