Disengagement of attention in chimpanzees was investigated by measuring latencies of reaching for a peripheral target under three conditions using three young and five adult-chimpanzees. In the overlap condition, the target appeared while the central fixation stimulus was being displayed constantly. In the no-overlap condition, the fixation stimulus disappeared when the target was presented. In the gap condition, the fixation stimulus disappeared before the presentation of the target. Results indicated that in adult-chimpanzees, the latencies in the overlap condition were longer than those in the gap condition, but not longer than those in the no-overlap condition. The latencies of one young chimpanzee (Pal) in the overlap condition were longer than those in the no-overlap and gap conditions. These results might suggest the immaturity of the attention process for disengagement in young chimpanzees.
