The attention process for disengagement in young chimpanzees and human children was investigated. Data on target pointing latencies in an overlap-gap experiment conducted with human children aged between 4 and 5 years were compared with those of 6-year old chimpanzees that had been tested in a previous study (Matsuzawa & Tanaka, 2007). Latency patterns in human children showed individual differences, and were related to the absolute latencies of the child. Latency patterns in young chimpanzees were similar to those of human children that pointed to targets with shorter latencies than to those with longer latencies. The results are plausible because young chimpanzees had shorter latencies than human children and suggest that the development of attention process in humans and chimpanzees might be related to the development of motor functions.
