Control over videotape enrichment for socially housed chimpanzees

Social behavior and solitary play were higher in subjects with control over the onset of videotapes, while scratching [generally regarded as a sign of tension] was higher in those groups who lacked control. The results indicate that giving chimpanzees control...

Positive reinforcement training paired with videotape exposure decreases training time investment for a complicated task in female chimpanzees

Subjects were 10 adult chimpanzees living in two groups. Five females were exposed to a 10-minute videotape of female chimpanzees being positively reinforced for successfully urinating into a cup. Immediately following videotape exposure, these subjects participated in a training session....

Naive chimpanzees’ (Pan troglodytes) observation of experienced conspecifics in a tool-using task

The authors investigated the occurrence of naive chimpanzees' (Pan troglodytes) spontaneous observation of experienced conspecifics during a tool-use task entailing honey fishing. The chimpanzees were presented with 20 kinds of tools of which 12 kinds were usable. Six pairs of...
