Age-related differences in performance on a puzzle feeder task

Total time manipulating the puzzle was similar for young and aged monkeys. However, average bout length was longer for young monkeys than for aged monkeys, suggesting more sustained attention to the task. [Species is not indicated; probably longtailed macaques.]

A foraging task reduces agonistic and stereotypic behaviors in pigtail macaque social groups

The results of this study indicate that the introduction of a naturalistic foraging task [sunflower seed scattered on woodchips] into groups of socially housed pigtailed macaques can have a significant effect on their behavioral repertoire, although there can be significant...

Positive reinforcement training to enhance the voluntary movement of group-housed chimpanzees within their enclosure

Positive reinforcement techniques are described and were applied to train groups of chimpanzees to move voluntarily into the indoor portions of their enclosures at the request of trainers and to be briefly restricted to those areas. ... Females required significantly...

Enlarging chimpanzee social groups: The behavioral course of introductions

All 42 introductions of chimpanzees (aged 3-43 years) in already established groups were successful. New group members were first introduced behind mesh fencing. Subsequent full physical contact did not further increase agonism. Stereotyped rocking declined in newly integrated individuals.
