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., 3, KJ00004724325, 論文}, pages = {1--10}, title = {チンパンジーにおける空間的注意機能の発達(2) : 注意解放機能の測定}, volume = {9}, year = {2007}, yomi = {マツザワ, マサコ and タナカ, マサユキ} }
