Laboratory rodents housed in standard, empty cages exhibit stereotypic behaviors that could indicate brain abnormalities, reported Joseph Garner of the University of California, Davis, at the International Society for Applied Ethology Congress. The stereotypies – pacing, incessant grooming, repetitive cage biting and scratching – are Rodents, and in particular laboratory mice, are of paramount importance to the members of The American Association of Immunologists (AAI) and the organization’s mission to advance the field of immunology. Not only has stereotype threat been widely criticized by on a theoretical basis, but has failed several attempts to replicate its experimental evidence. The findings in support of the concept have been suggested by multiple methodological reviews to be the product of publication bias. Self-fulfilling prophecy A large variety of rodent behavioral tests are currently being used to evaluate traits such as sensory-motor function, social interactions, anxiety-like and depressive-like behavior, substance dependence and various forms of cognitive function. Most behavioral tests have an inherent complexity, and their use requires consideration of several aspects such as the source of motivation in the test The value of small rodents to biomedical research is beyond question. About half of the extramural grants awarded annually by the US National Institutes of Health require some use of laboratory animals.
Laboratory primates experience a plethora of stressors, potentially including injections, blood drawing, cage changes, physical and chemical restraint, and participation in scientific procedures. 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. In this chapter we provide an overview of the behavior of rodents. We also provide references for testing details. Most of the behavioral methodology comes from research on rats, but the ethograms of rodents are similar enough to allow for generalization of the methods, if not many aspects of behavior, to other species. Many stereotypies are signs of frustration, with the subject being chronically thwarted from expressing basic activities such as taking a few free steps in one direction, climbing and perching, retreating to a secluded place, foraging, and interacting with another conspecific (Reinhardt). allowed to obtain a piece of food on a tray by reaching through a slot in its cage.
Stereotypies are defined in two ways: Repetitive, invariant behaviour without apparent immediate function. Repetitive behaviours caused by the animal’s repeated attempts to adapt to its environment or by a dysfunction of the central nervous system. Both definitions agree that stereotypies are repetitive behaviours.

Because more than 95% of such use involves mice and rats, public investment in rodent … Unfortunately, rodent behavioral testing in the laboratory setting have proved difficult and test results may vary depending on the person performing the experiment (Chesler et al., 2002), in which laboratory the experiments are performed (Crabbe et al., 1999) and environmental factors including for example animal housing (Richter et al., 2010).To further advance the field of rodent behavioral In the course of a project on the history of stress, Jon Adams of the London School of Economics and I have traced how evidence of crowding pathology, generated in the rodent laboratories of NIMH, travelled to an alternative setting: the buildings, institutions and cities of the social scientist, city planner, architect and medical specialist.

circumstance (Reinhardt). In caged mice, barbering (fur and whisker trimming) is another example of a stereotypy that has become a normative behavior pattern within the context of inadequate living conditions (Anonymous). It is the artificial environment in which stereotypies develop that is “abnormal” as it does not allow
In laboratory rats and mice, grooming is the most common activity other than sleep, and grooming stereotypies have been used to investigate several animal models of anxiety and depression. [13] Examples of stereotypical behaviours include pacing, rocking, swimming in circles, excessive sleeping, self-mutilation (including feather picking and excessive grooming), and mouthing cage bars. Experimental evidence seems to indicate that environmental factors such as cage size, housing type, stress and boredom which are often cited as the "causes" of stereotype in laboratory animals, do not necessarily cause the behaviour. Not all monkeys that experience these environmental conditions develop stereotypic behaviour . All mice were twice as likely to initiate syntactic chains in the laboratory than at home (F(1, 82) = 85.73, p < 0.001), and mutant mice in particular initiated approximately 25% more chains than wild-type mice in the laboratory environment (F (1,86) = 17.315, p < 0.001; Figure 4), compared to only 5% more in the home environment.

Locomotion is the main behaviour animals use to avoid aversive stimuli or gain access to resources, thus pacing stereotypies may provide a window into motivation to leave the enclosure.
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. The standard experimental design of his laboratory studies was to allow one group of rats to show a coping response, i.e.

1.1 The Origins of Laboratory Behavioral Research. 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).
