Music influences rhythmic movement in humans, suggesting a link between the brain’s auditory and motor areas. Understanding chimpanzees’ predisposition to process music could shed light on the evolutionary origins of humans’ response to music. Yuko Hattori and Masaki Tomonaga (pp. 936–942) examined how music affects rhythmic movement, or repetitive movement of the entire body or body parts, in 7 chimpanzees who listened to 6 2-minute piano sounds with different tempos for 6 days. In response to an auditory stimulus, the chimpanzees often swayed and sometimes made rhythmic hand clapping and foot tapping. Compared with female chimpanzees, male chimpanzees were more likely to respond to sound with vocalization and sway rhythmically for longer durations. A separate experiment focused on the chimpanzee most responsive to the auditory stimuli. The chimpanzee was exposed to 4 2-minute sound sessions for 24 days. Both random and regular beats induced rhythmic swaying in the chimpanzee, and beat tempo affected the chimpanzee in a bipedal but …

音乐会影响人类的节奏运动，暗示大脑的听觉和运动区域之间的联系。了解黑猩猩对音乐进行处理的倾向性，可以阐明人类对音乐反应的进化起源。Yutor Hattori和Masaki Tomonaga（pp。936-942）研究了音乐如何影响7名黑猩猩的节律性运动或整个身体或身体部位的重复性运动，他们听了6天2分钟不同速度的2分钟钢琴声。为了响应听觉刺激，黑猩猩经常摇晃，有时会做出有节奏的拍手和拍打脚步。与雌性黑猩猩相比，雄性黑猩猩更有可能通过发声和有节奏地摆动声音来响应较长的持续时间。一个单独的实验侧重于对听觉刺激最敏感的黑猩猩。黑猩猩暴露于4分钟2分钟的声音持续24天。随机和常规拍子都引起黑猩猩的有规律的摇摆，拍子的节奏影响了双足动物的黑猩猩，但是…
