尽管非人类灵长类动物具有高度发达的视觉认知能力，但它们在圈养环境中很少有机会发挥这种能力。视频呈现可以再现复杂、真实、视觉世界的多种特征。因此，视频展示可以作为圈养灵长类动物的环境丰富。本研究评估了新颖性和视频内容的丰富效果，以及使用新开发的技术（包括网络共享YouTube视频和红外距离传感器）对视频的控制。在4只单独饲养的猴子和6只成对饲养的猴子中，分别获得了10天无视频显示和10天无视频显示的基线数据。随后，研究人员让这些猴子观看有关同种动物、人和动画的视频，并对其进行了30天的观察。在某些日子里，猴子可以控制视频，只有当受试者直接坐在显示器前面时，视频才会播放。然后在没有录像的情况下进行另外10天的观察。每天记录60分钟的行为，如观看视频的时间，异常行为和在显示器前花费的时间，采用瞬时采样，间隔30秒。猴子在播放视频时（单独饲养：11.3个采样点，成对饲养：7.7个采样点）比不播放视频时（单独饲养：22.5个采样点，成对饲养：10.8个采样点）表现出更少的异常行为（P < 0.001）。在观察期间的异常行为没有显示出对视频习惯的证据。观看视频的频率和异常行为因视频内容的不同而不同（P < 0.001）。在他们可以控制视频的日子里（单独居住：89.1个采样点，成对居住：17.6个采样点），受试者在显示器前花费的时间比他们没有控制的日子（单独居住：70.1个采样点，成对居住：7.3个采样点）花费的时间更多（P < 0.001）。这表明他们优先选择观看视频。这些结果表明，视频演示可以作为一种有效的技术来减少圈养日本猕猴的异常行为。视频的内容和可控性对它们的行为有影响，这表明实施视频丰富（包括同种视频和视频可控性）可以改善动物福利。在了解物种特有特征的基础上实施可有助于有效地丰富环境。(C) 2012 Elsevier B.V.版权所有
Although nonhuman primates have highly developed visual cognitive abilities, they have few opportunities to exert such abilities in captivity. Video presentation can reproduce multiple features of the complex, real, visual world. Therefore, video presentation can be expected to act as environmental enrichment for captive primates. The present study evaluated the enriching effects of novelty and content of videos as well as control over videos using newly developed technology including network-shared YouTube videos and an infrared distance sensor. Baseline data were obtained for 10 days without video display and then 10 days with the display showing no videos in four individually housed monkeys and six pair-housed monkeys. The monkeys were then exposed to videos of conspecifics, people, and animation and observed for 30 days. In some days, the monkeys had control over videos such that videos played only when subjects sat directly in front of the display. Observations were then taken for an additional 10 days with no videos. Behaviours such as time watching videos, abnormal behaviour and time spent in front of display were recorded for 60 min per day using instantaneous sampling with a 30-s interval. Monkeys displayed fewer abnormal behaviours when the video was playing (individually housed: 11.3 sampling points, pair-housed: 7.7 sampling points) than when the video was not playing (individual housed: 22.5 sampling points, pair-housed: 10.8 sampling points) (P < 0.001). The abnormal behaviour over the course of the observation days showed no evidence of habituation to videos. The frequency of watching the videos and abnormal behaviour differed depending on the presented contents of videos (P < 0.001). The subjects spent more time in front of the display in the days in which they could control the videos (individually housed: 89.1 sampling points, pair-housed: 17.6 sampling points) than in those in which they had no control (individually housed: 70.1 sampling points, pair-housed: 7.3 sampling points) (P < 0.001). suggesting that they were preferentially choosing to watch the videos. These results suggest that video presentation can be a useful technique to decrease abnormal behaviour of captive Japanese macaques. The content and controllability over videos were influential on their behaviour, suggesting that implementation of video enrichment that includes conspecifics videos and controllability over videos can improve animal welfare. Implementation based on an understanding of species-specific characteristics can contribute to effective environmental enrichment. (C) 2012 Elsevier B.V. All rights reserved.
