Social awareness in monkeys

Tests of self-awareness in nonhuman primates have to date been concerned almost entirely with the recognition of an animal's reflection in a mirror. By contrast, we know much less about non-human primates' perception of their place within a social network,...

Videotape viewing as enrichment during recovery of hospitalized monkeys

During videotape exposure monkeys did not remove their sutures. Animals that had previously withdrawn from food were observed eating during videotapes showing primates eating.

The lower-row cage may be dark, but behavior does not appear to be affected

The situation of 3 upper-row single-caged females was compared with that of 6 lower-row single-caged females. Mean light levels at nine different positions within the cage were significantly lower in bottom-row cages than in upper-row cages. Not only did light...

A comparison of cell-mediated immune responses in rhesus macaques housed singly, in pairs, or in groups

The data demonstrate that social housing condition affects immune responses. While not unidirectional, these effects generally suggest enhanced immune responses for socially housed animals. .... It is our contention that strong social relationships, particularly the affiliative interactions that characterize our...

A few new developments in primate housing and husbandry

A major focus of this paper is an examination of the complementary role that behavioral management strategies play in the establishment and enhancement of well-defined nonhuman primate research resources. .... Additionally, I will discuss the use of positive reinforcement training...

Initiating a computer-assisted enrichment system for captive chimpanzees

The joystick apparatus was used without significant decrease throughout 2-hour sessions and across the 3-month duration of the study. ... Food rewards were automatically dispensed upon completion of each trial. Juvenile subjects spent 20% of the 2-hour sessions utilizing the...

Environmental enrichment for New World primates: Introducing food-irrelevant objects and direct and secondary effects

Group-housed subjects were offered different commercial toys. Findings led to the conclusion that a routine rotation of objects could yield practical and effective enrichment technique.

Changing the housing standard for monkeys in laboratories

Permanent confinement in such extremely small, barren enclosures causes many individuals to develop the monotonous habits of stereotypically pacing back and forth, running in circles, somersaulting or bouncing up or down. ... The striking difference of illumination between upper and...

Blood collection procedure of laboratory primates: A neglected variable in biomedical research

A survey of 75 biomedical articles dealing with stress-dependent blood parameters in caged primates revealed that the conditions under which blood collection occurred were in most cases [72%] described either not at all or so haphazardly that it would be...
