Abnormal/Problematic Behavior

Abnormal behavior in a captive chimpanzee colony

The purpose of this study was to link abnormal behaviors often expressed by chimpanzees living in captive environments to factors related to their care and housing. Individuals who had spent more time with their mothers had less abnormal behavior. Access...

Effect of feed and environmental enrichment on development of stereotypic wire-gnawing in laboratory mice

Enrichment significantly reduced stereotypic wire-gnawing in pair-housed male mice by 40%, presumably as a consequence of the cover provided by the cardboard tubes. This is substantiated by observations that the tubes were used as a place to retreat upon disturbance...

Cage toys reduce abnormal behavior in individually housed pigtail macaques

Providing multiple manipulable toys as enrichment for [single-caged] pigtail macaques was effective in reducing abnormal behavior during 30- min observation session. The use of the toys was reduced over time. The Kong toy was used most consistently.

Risk factors for self-injurious behavior in captive rhesus monkeys (Macaca mulatta)

Research has shown that approximately 10% of captive, individually housed monkeys have had some veterinary record of self-injurious behavior within their life-time. The incidence of self-biting was 14% [!] in a test colony of 188 male individually housed rhesus macaques....

Abnormal behavior: Action not reaction

This paper will present an overview of the literature on abnormal behavior, in order to establish a context for the effective use of enrichment to address these types of problems. .... Abnormal behavior may function as an adaptive coping response...

Towards an understanding of stereotypic behaviour in laboratory macaques

Comprehensive discussion and review of the possible causes of stereotypic behaviour in laboratory macaques. A great deal of debate and controversy has surrounded what does does and does not constitute psychological well-being in primates [p. 22].

Self-injurious behavior is decreased by cyproterone acetate in adult male rhesus (Macaca mulatta)

Self-injurious behavior (SIB) presents a serious problem in laboratory macaques that cannot be socially housed forscientific reasons and among institutionalized children and adults where it is often associated with different forms ofbrain dysfunction. We have experienced limited success in reducing...
