Stereotypies fall into two categories: Vocal; Motor; Vocal stereotypies may sound like babbling, humming, or a sing song sound. Among male rodents, elimination of the VNO seems to have different consequences (Hernandez-Gonzalez, et al., 2008). In male rats, removal of the VNO caused a reduction in the mounts ending in intromission, suggesting deficiencies in erection and activity in the striated penile muscles. Stereotypies are widely misinterpreted as a model of OCD. However, human stereotypy precludes a diagnosis of OCD (i.e. they are mutually exclusive diagnoses in humans), and the neuopsychological and neurobiological findings in animals support the conclusion that animal stereotypies are not a model of human OCD. In a 2000 lawsuit settlement with animal-rights and anti-animal research groups, USDA had agreed to consider including laboratory rodents and birds under its regulations. However, Sen. Jesse Helms (R-N.C.) took steps to negate the settlement in February by inserting a brief clause into the Senate's version of the Farm Bill specifying the animals were exempt from the AWA. Many laboratory animals, including mice and rats, are chronically stressed which can also negatively affect research outcomes and the ability to accurately extrapolate findings to humans.

This unit presents a quantitative, observational method for the assessment of rodent stereotyped behavior which consists of motor responses that are repetitive, invariant, and seemingly without purpose or goal. The most classic behavioral pattern that is characteristic of stereotypy is that elicited … The results indicated that enrichment is more determinant than cage size, as more voles developed stereotypies in SB and BB than in SR and BR. Stereotypic behavior is a malfunctional abnormal behavior. It is the consequence of an abnormal animal in an abnormal environment. These behaviors are unvarying in form and are performed almost identically on each repetition.
In our previous report, more than 4% of caged young layers were observed to perform stereotyped feather pecking during the period from 13: 00 to 15:0010). However, detailed descriptions, especially qualitative analysis, on poultry stereotypies … Indeed, stereotypies (abnormal behaviour) in captive wild animals may arise from repeatedly thwarted (i.e., unsuccessful) attempts to escape confinement (Dantzer, 1986;Mason, 1991; Clubb and and Stereotypies in Zoo Animals: WhatÕs Been Done and Where Should We Go Next?

The study of animal behavior has a long history, dating back over 2000 years; however laboratory behavioral research became popular in the twentieth century with the rise of behaviorism, with research using animal models to understand more about the human processes of learning and memory and the comparative abilities of animals (Klopfer, 1993). In this article, we refer to an original opinion paper written by Prof. Frank Beach in 1950 (“The Snark was a Boojum”). In his manuscript, Beach explicitly criticised the field of comparative psychology because of the disparity between the original understanding of comparativeness and its practical overly specialised implementation. Berkson et al.
The inability of the animal to escape from these experiences might lead to adoption of stereotyped behaviours as a means of coping with an aversive environment. Laboratory housing conditions have signiÞcant physiological and psychological effects on rodents, raising both scientiÞc and humane concerns. Published studies of rats, mice and other rodents were reviewed to document behavioural and psychological problems attributable to predominant laboratory housing conditions. Studies indicate that rats and
One of the factors within a captive environment that may affect the establishment of stereotypies is exploratory behaviours that are directed to the outside of a cage. Research suggests that some common stereotypic behaviours seen in mice, wire-gnawing for example, may originate from such exploratory behaviours.
