对115只圈养黑猩猩的手势交流功能进行了研究。当受试者对放在他们够不着的地方的食物做手势时，他们的手的使用情况被测量。手势的使用分布与性别、年龄、养育史、手势类型以及受试者是否在打手势时发声有关。总体而言，用右手打手势的黑猩猩明显多于用左手打手势的黑猩猩，尤其是雌性和成年黑猩猩。食物乞讨更多地偏向右手而不是指着，同时发声的受试者比不发声的受试者更多地使用右手手势。综上所述，这些数据表明，在黑猩猩中，指代的、有意的交流行为，以手势的形式，被偏向于左半球。
Hand use in gestural communication was examined in 115 captive chimpanzees (Pan troglodytes). Hand use was measured in subjects while they gestured to food placed out of their reach. The distribution of hand use was examined in relation to sex, age, rearing history, gesture type, and whether the subjects vocalized while gesturing. Overall, significantly more chimpanzees, especially females and adults, gestured with their right than with their left hand. Foods begs were more lateralized to the right hand than pointing, and a greater prevalence of right-hand gesturing was found in subjects who simultaneously vocalized than those who did not. Taken together, these data suggest that referential, intentional communicative behaviors, in the form of gestures, are lateralized to the left hemisphere in chimpanzees.
