In animal behaviour, stereotypy, stereotypic or stereotyped behaviour has several meanings, leading to ambiguity in the scientific literature. [1] A stereotypy is a term for a group of phenotypic behaviours that are repetitive, morphologically identical and which possess no obvious goal or function. [ 2 ]
Some abnormal behaviours may be related to environmental conditions (e.g. captive housing) whereas others may be due to medical conditions. The list does not include behaviours in animals that are genetically modified to express abnormal behaviour (e.g. reeler mice). A polar bear performing stereotyped pacing.
Animal stereotype may refer to: Stereotypy (non-human), repetitive behaviours of animals; the term has two meanings: repetitive "abnormal" behaviours due to abnormal conditions with no obvious function; repetitive normal behaviours due to physiological or anatomical constraints
These behaviors may be maladaptive, involving self-injury or reduced reproductive success, and in laboratory animals can confound behavioral research. [17] Examples of stereotyped behaviors include pacing, rocking, swimming in circles, excessive sleeping, self-mutilation (including feather picking and excessive grooming), and mouthing cage bars.
Most behaviors which are both fixed action patterns and occur in more complex animals, are usually essential to the animal's fitness, or in which speed (i.e. an absence of learning) is a factor. [6] For instance, the greylag goose's egg-retrieval behavior is so essential to the survival of its chicks that the fitness of the parent bird is ...
These behaviors sometimes share characteristics with obsessive-compulsive behavior, including a high degree of similarity in form and use among many individuals and a repetitive dimension. There are many observable animal behaviors with characteristic, highly conserved patterns. One example is grooming behavior in rats. This behavior is defined ...
The idea of swarm robots has been around for some time but researchers are now looking more closely at nature for robot design inspiration.
Stereotypies are invariant, repetitive behaviour patterns with no blatant function or objective, and seem to be restricted to captive and/or mentally-impaired animals. [11] Stereotypies are the result of inability of an animal to perform a normal behaviour due to external environmental conditions or circumstance.
