| Outline of Final Research Achievements |
Human adults perceptually group multiple component parts as a whole. In the present study, I compared chimpanzees and humans to examine what aspects of perceptual grouping is unique to humans. I also compared human children and adults to examine how perceptual grouping develops. In a series of experiments, I was particularly interested in the configural superiority effect: despite its irrelevance, redundant contexts improve the participants' performance when the context perceptually grouped with the task-related stimuli. When the shape perception was examined using geometric figures, chimpanzees and human children showed similar configural superiority effect to human adults. However, they failed to show the effect in face perception. I also revealed that human gaze and objects is perceptually grouped when the gaze is oriented towards the objects. In summary, basic principles of perceptual gestalts are shared between humans and chimpanzees, as well as human adults and children.
