The experiment setting (A) and the general procedure (B). (A) Chimpanzee Ai is doing the task. She is touching an inverted sample stimulus. (B) In each trial, a start key showed on the screen first. After touching the start key, the participants saw a sample appear on the screen. It would stay for 500 ms and then disapper upon touching. Then, four choice options appeared without any delay. The original pictures of the chimpanzee image on the screen (A) and the silhouette chimpanzee images (B) were provided by Kumamoto Sanctuary, Wildlife Research Center of Kyoto University.
