What impression is formed by them? It is important issue to consider people's psychological reactions to the individuals and objects with the same face such clone humans and humanoid robots when the mass production of them become possible in the future. We made two hypotheses about this issue. One is that individuals with exactly the same face would be positively evaluated because a previous study revealed that processing fluency was associated with positive evaluation (Reber, Winkielman, & Schwarz, 1998). Another is that they would be negatively evaluated because objects which have features with realism inconsistency are associated with negative evaluation (MacDorman and Chattopadhyay, 2016). To test these hypotheses, the present study investigated what impressions were formed when people observed a scene in which six individuals with exactly the same face exist. 121 Japanese people were participated in the experiment online. We made three kinds of stimuli pictures; pictures of six individuals with the same face (clone condition), pictures of an individual (single condition), and pictures of six individuals with faces different from each other (non-clone condition). Participants evaluated the impression (eeriness, valence, and realism) of the pictures on a 7-point Likert-scale. The results showed that the pictures in the clone condition were significantly highly eerie, realistic, and negative compared to the pictures in the other conditions. Therefore, it is suggested that individuals with the same face induced negative impressions. This is a new devaluation effect―the clone devaluation effect.
