许多人声称社会刺激对灵长类动物是有益的，但很少有研究明确地证明了它们的奖励价值。在这里，我们研究了黑猩猩是否会对有机会观看相同的社交内容产生明显的反应，与动态（视频：实验1）和静态（图片：实验2）控制内容相比。我们还探讨了社会奖励变化与社会行为和认知之间的关系。我们让圈养的黑猩猩在四次一小时的会议中使用触摸屏（两次“同类型社交”和两次“控制”）。这些实验包括10个15秒的视频（或实验2中的图片），要么是黑猩猩从事各种行为（社会条件），要么是车辆、人类或其他动物从事某些活动（控制条件）。我们记录了每只黑猩猩对触屏的反应次数和观看刺激的频率。独立t检验显示，在触摸和观看社交视频或控制视频方面，性别或抚养方式没有差异（p < 0.05）。重复测量方差分析显示，在社交视频会话中，黑猩猩触摸和观看屏幕的频率明显高于对照视频会话。此外，在实验2中，虽然黑猩猩在社交阶段触摸屏幕的次数并不比对照图片组多，但它们确实更频繁地观看屏幕。此外，先前在社会认知任务中表现较好的黑猩猩，在触屏任务中参与更多的附属行为，观看了更高比例的社交视频。这些结果与社会动机理论相一致，表明社会刺激在本质上是有益的，因为与控制内容相比，黑猩猩对观看相同社会内容的机会做出了更明显的反应。
Many claim that social stimuli are rewarding to primates, but few, if any, studies have explicitly demonstrated their reward value. Here, we examined whether chimpanzees would produce overt responses for the opportunity to view conspecific social, compared to dynamic (video: Experiment 1) and static (picture: Experiment 2) control content. We also explored the relationships between variation in social reward and social behavior and cognition. We provided captive chimpanzees with access to a touchscreen during four, one-hour sessions (two ‘conspecific social’ and two ‘control’). The sessions consisted of ten, 15-second videos (or pictures in Experiment 2) of either chimpanzees engaging in a variety of behaviors (social condition) or vehicles, humans, or other animals engaged in some activity (control condition). For each chimpanzee, we recorded the number of responses to the touchscreen and the frequency of watching the stimuli. Independent t-tests revealed no sex or rearing differences in touching and watching the social or control videos (p>0.05). Repeated measures ANOVAs showed chimpanzees touched and watched the screen significantly more often during the social compared to control video sessions. Furthermore, although chimpanzees did not touch the screen more often during social than control picture sessions in Experiment 2, they did watch the screen more often. Additionally, chimpanzees that previously performed better on a task of social cognition and engaged in more affiliative behavior watched a higher percentage of social videos during the touchscreen task. These results are consistent with the social motivation theory, and indicate social stimuli are intrinsically rewarding, as chimpanzees made more overt responses for the opportunity to view conspecific social, compared to control, content.
