Allelomimetic behavior or allomimetic behavior is a range of activities in which the performance of a behavior increases the probability of that behavior being performed by other nearby animals. Allelomimetic behavior is sometimes called contagious behavior and has strong components of social facilitation, imitation, and group coordination. It is usually considered to occur between members of the same species.〔(【引用サイトリンク】title=Allelomimetic behavior )〕 Lindsay refers to the imitative or copycat behavior in social animals.〔Lindsay, S.R., (1999). ''Handbook of Applied Dog Behavior and Training: Volume One, Adaptation and Learning''. Iowa State University Press〕 It can occur in any species at any stage in their life. Even if a dog can sense no danger, if an owner "(up ) alertly and with pose in () voice () 'What's that? Who's there?', the dog will mimic the owner's attitude."〔Robert M Miller, ''Understanding the Ancient Secrets of the Horse's Mind'' (1999)〕 According to Genetics and the Social Behavior of the Dog, "puppies first do this at about five weeks of age"〔John Paul Scott and John L Fuller, (''Genetics and the Social Behavior of the Dog: The Classic Study'' ) (1965)〕 Adult dogs and cats who live together tend to sleep, eat and play together. These are examples of allelomimetic behavior〔Linda P Case, (''Canine and Feline Behavior and Training: A Complete Guide to Understanding Our Two best Friends'' ) (2010)〕 Other examples in nature include collective decisions in social insects, such as pheromone-based path selection in ants, where the choice of only one path drives all the workers towards the same food source,〔Detrain, C., Deneubourg, J.-L. and Pasteels, J. (1999). ''Information Processing in Social Insects''. Basel: Birkhauser-Verlag〕 or the choice of a single aggregation site by cockroaches.〔Jeanson, R., Rivault, C., Deneubourg, J.-L., Blanco, S., Fournier, R., Jost, C. and Theraulaz, G., (2005). Self-organized aggregation in cockroaches. Animal Behaviour, 69: 169-180〕 Examples in vertebrates include schooling fishes〔Grunbaum, D., Viscido, S. and Parrish, J.K., (2004). Extracting interactive control algorithms from group dynamics of schooling fish. In: ''Lecture Notes in Control and Information Sciences'' (Ed. by V. Kumar, N.E. Leonard and A.S. Morse), pp. 103-117. Springer-Verlag.〕 and switching between behaviours by sheep.〔Gautrais, J., Michelena, P., Sibbald, A., Bon, R. and Deneubourg, J-L. (2007). Allelomimetic synchronization in Merino sheep. Animal Behaviour, 74: 1443-1454〕 ==Function== Group cohesion: Social animals often benefit by behaving in a simailar manner to others within their group. This means that when animals switch behaviours, e.g. from lying to grazing, a degree of synchrony is beneficial. Sometimes this synchrony can be provided by environmental cues, at other times it is provided by the group members themselves. In 1978, Clayton wrote "...where environmental stimuli only provide gross synchrony, socially facilitated behaviour will provide finer-scale synchrony, and, what is functionally important, greater cohesion of the social group’.〔Clayton, D.A., (1978). Socially facilitated behavior. Quarterly Review of Biology, 53: 373-392〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Allelomimetic behavior」の詳細全文を読む スポンサード リンク
