Figure 6

Examples of stimuli. Top row shows chimpanzee stimuli, and bottom row shows human stimuli. From left to right, they are sample stimuli of the intact body condition, the face-blur condition, the body-blur condition, the body-only condition and the silhouette condition. In the face-blur condition, all stimuli had the faces replaced by mosaic patterns, and those in the body-blur condition had the mosaic patterns over the bodies except for the faces. The stimuli in the body-only condition were all headless bodies. Stimuli of human bodies were manipulated in the same manner. The original pictures of the chimpanzee images were provided by Kumamoto Sanctuary, Wildlife Research Center of Kyoto University. The original picture of the human images was taken by the authors.
