TL;DR

It was shown that repeated elicitation of immobility, and not just handling, was responsible for reduced response durations after multiple exposures to manual restraint, and habituation was a function of the number of stimulus presentations.

Abstract

The habituation of tonic immobility in chickens was examined in six studies. It was shown that repeated elicitation of immobility, and not just handling, was responsible for reduced response durations after multiple exposures to manual restraint. Habituation was a function of the number of stimulus presentations and, in addition, proved surprisingly durable, with diminished reactions using lasting at least 2.5 mo. Strain differences were found in the number of trials required to reach a criteria of habituation, and habituation proceeded faster when immobility termination was self-paced as opposed to experimenter induced. Also, massed trials produced robust sensitization effects rather than diminished responsiveness.

It is shown that animal hypnosis, or tonic immobility, is an easily induced and readily quantifiable phenomenon found in many different species.

Red foxes appear to have adapted to the escape of death-feigning ducks by learning to kill some birds soon after capture and by the evolution of an appendage-severing behavior.

It was concluded that the experimenter's eyes were of primary importance in sustaining the immobility episode, and the results were interpreted in terms of the fear hypothesis of animal hypnosis and predator-prey relationships.

Production Red chickens were selectively bred on the basis of having shown prolonged or brief immobility reactions at 21 days of age to conclude that tonic immobilities has an unusually large heritability component.

It is suggested that changes in responsiveness are best described with the aid of the term SAP, and the main outlines of the theory are well supported by observational and experimental evidence but the “motivational impulses” model seems to lead to a number of additional assumptions.

The optimal period of manual restraint, by way of producing the most durable immobility response, was found to be 15 sec, and pretest holding conditions were shown to exert a significant influence on the reaction in naive birds.

36 Citations1970A. M. Prestrude, F. T. Crawford

The lizard, Iguana iguana appears to be a good preparation with which to study the tonic immobility response, which can be reliably induced in iguanas by a combination of inversion, restraint, and moderate pressure.

It was interpreted to mean that habituation depends upon not only eliciting the same response with a series of repeated, nonreinforced stimuli, but that it is necessary as well to insure that the nature and location of the stimulus is repeated as closely as possible.
