Abnormal/Problematic Behavior

Inter-group variation in abnormal behavior in chimpanzees (Pan troglodytes) and rhesus macaques (Macaca mulatta)

It is suggested social learning processes are involved in the propagation of these behaviors.

Vasectomies as part of an environmental enrichment plan for primates

Pair housing following vasectomy has also been implemented for adult male [rhesus] macaques that engaged in self-injurious behavior (SIB). The incidence of SIB was significantly decreased or eliminated following these interventions.

The effect of four enrichment conditions on abnormal behavior in seven singly caged baboons (Papio hamadryas anubis)

Seven singly caged juvenile baboons were selected for behavioral intervention due to the severity of their abnormal behavior. Continuous all occurrence sampling method determined durations of abnormal and common behaviors throughout the ten-week study. Analysis of baseline behavior (fifteen 30-minute...

Environmental enrichment: effects on stereotyped behavior and neurotrophin levels

These results provide evidence that the enrichment-related prevention of stereotyped behavior in deer mice is associated with increased BDNF in the striatum.

Barbering (fur and whisker trimming) by laboratory mice as a model of human trichotillomania and obsessive-compulsive spectrum disorders

In a typical cage of barbered mice, all but one individual will have near-identical patterns of hair loss. The intact individual (the 'barber') is removing hair from its companions. .. Barbers hold down their cage mates [who adopt a defensive...

The effect of environmental manipulation on behavior, salivary cortisol, and growth of piglets weaned at 14 days of age

Environmental enrichment [hanging rope and rubber tire tube] results in less anomalous behaviour, reduced fear response to humans and better growth. Environmental enrichment did not affect salivary cortisol.

Abnormal behaviour in laboratory monkeys

The success of inanimate environmental enrichment in controlling severe behaviour disorders [such as self-injurious behaviour] has been limited, although a few studies suggest some benefits. Providing tactile social contact is comparatively more successful in reducing abnormal behaviour in some monkeys...

Cage enrichment and mouse behaviour

Mice housed in standard cages show impaired brain development, abnormal repetitive behaviours (stereotypies) and an anxious behavioural profile, all of which can be lessened by making the cage environment more stimulating. But concerns have been raised that enriched housing might...

Housing and stereotyped behaviour: Some observations from an indoor colony of vervet monkeys (Chlorocebus aethiops)

Adult females displaying stereotypies in single cages were exposed sequentially to a foraging log and an exercise cage, as well as cages of varying complexity and dimensions. In another study females and males housed single in the bottom row, and...

The role of the image of a conspecific in the regulation of stereotypic head movements in the horse

Weaving was significantly less when the horses were provided with the image of a horse's face (mean percentage of observations +/- S.E.M.; 5.56 +/- 1.57), compared to both the pixilated (14.85 +/- 3.06) and white (20.52 +/- 4.12) images. Nodding...
