Reflexive fighting in response to aversive stimulation.

摘要: Reflexive fighting was elicited between paired rats as a reflex reaction to electric shock prior any specific conditioning. Such fairly stereotyped and easily differentiated from the rats' usual behavior. The strength of this not attributable apparent operant reinforcement. Elicitation direct function enclosed floor area nonmonotonic intensity. Failure scramble polarity electrified grid produced inconsistent fighting. Under optimal conditions consistently by regardless rat's sex, strain, previous familiarity with each other, or number present during shock. Repeated presentations did produce an appreciable decrease in until signs physical debility appeared. Although cause rat attack inanimate objects, it movements toward other small animals. Failure guinea pigs defend themselves revealed that elicitation does require reciprocal attack. Paired hamsters showed reactions similar those rats, whereas failed fight. Electrode heated but intense noise cooled not.
