研究人员对幼年黑猩猩对身后物体的联合视觉注意力进行了研究。最近的一项研究表明，13 个月大的黑猩猩婴儿可以遵循人类的社交线索，包括扫视（Okamoto、Tomonaga、Ishii、Kawai、Tanaka 和 Matsuzawa，2002a）。在人类中，12 个月大的孩子不会注视身后的物体，但 18 个月大的孩子会这样做（Butterworth & Jarrett，1991）。在本研究中，从 13 个月大开始，黑猩猩幼崽就被测试看两个相同物体之一，实验者通过指向或转头来表示。物体被放置在拍摄对象的前面或后面。在我们的一系列实验中，我们使用移动或静止的物体作为目标。此外，实验者在每组试验开始时都操纵计算机。结果表明，到20个月大时，婴儿就能可靠地遵循实验者的提示并回头看向身后的目标。移动目标比静止目标引起更多的反应，并且受试者在看到实验者操纵计算机后表现出更多的跟随反应。
An infant chimpanzee's joint visual attention to objects behind him was investigated. A recent study has shown that a 13-month-old infant chimpanzee can follow human social cues including glancing (Okamoto, Tomonaga, Ishii, Kawai, Tanaka, & Matsuzawa, 2002a). In humans, 12-month-olds do not follow gaze to objects behind them but 18-month-olds do (Butterworth & Jarrett, 1991). In the present study, from 13 months old, the infant chimpanzee had been tested to look at one of two identical objects, which an experimenter indicated by pointing or head turning. The objects were set in front of or behind the subject. In our series of experiments, we used moving or stationary objects as targets. Moreover, the experimenter manipulated a computer at the onset of each block of trials. The results show that by the age of 20 months, the infant reliably followed the experimenter's cues and looked back to the target behind him. Moving targets elicited more responses than stationary targets, and the subject showed more follow responses after having seen the experimenter manipulating the computer.
