Three chimpanzees (Pan troglodytes) were provided with 18 different stimulus pages for drawing. The resulting 618 drawings were coded for drawn marks, and results were compared with early reports on ape drawing (Morris, 1962; Schiller, 1951) and with more recent systematic studies (Smith, 1973). The findings of the present study confirm Smith's observations of a tendency for the animals to draw closer to the center and toward the bottom of the page. No evidence for perceptual balancing was observed in drawings produced on pages with lateral figures, nor was any evidence for closure apparent with complex figures. The present results agree with earlier findings that chimpanzees will engage in drawing activities without training or reinforcement, and this behavior may reflect their intrinsic interest in exploratory and manipulative play.
为三只黑猩猩（黑猩猩属）提供了18张不同的绘画刺激页面。对由此产生的618幅画作的绘制痕迹进行了编码，并将结果与早期关于猿类绘画的报告（莫里斯，1962年；席勒，1951年）以及最近的系统研究（史密斯，1973年）进行了比较。本研究的结果证实了史密斯的观察结果，即动物有向页面中心和底部靠近绘制的倾向。在有横向图形的页面上绘制的画作中，未观察到感知平衡的证据，复杂图形也未表现出任何闭合的证据。目前的结果与早期的发现一致，即黑猩猩在没有训练或强化的情况下也会参与绘画活动，这种行为可能反映了它们对探索性和操作性游戏的内在兴趣。
