Enrichment is a growing field in animal research. Over the years, it has become not only respected, but mandated. With the advancement of technology, methods of enrichment have diversified. Video enrichment is a fairly recent addition in the enrichment field. As such, little investigation has been done on whether or not this form of enrichment is beneficial. The purpose of this study is to show what benefits, if any, video enrichment has on paired and individually housed non-human primates. A behavioral study was conducted on 16 paired and 16 individually-housed cynomolgus macaques. Behavior frequencies were recorded pre-video and after the addition of video enrichment. Frequencies were then grouped into species-typical, species-atypical, and species-neutral categories for evaluation of the data. Results show a decrease in all but pair-housed species-atypical behavior with the addition of video enrichment, indicating that video enrichment may be beneficial to individually-housed and not pair-housed animals. Furthermore, variation in the data reveals that the benefit of video enrichment is based largely on the individual.
