“…The freezing response, characterized by crouching and immobility, represents a conditional reaction of rats to conditional stimuli associated with aversive events (Blanchard & Blanchard, 1969;Bolles & Coltier, 1976;Fanselow, 1980). We have noted, as have others (e.g., Korn & Moyer, 1966;Martin & Miller, 1981), that during the early course of habituation training to an acoustic startle stimulus, rats exhibit freezing behavior. The influence of freezing on the rate of acoustic startle decrements has not, however, been systematically examined.…”

“…However, we have shown that it is the sensitization process and not the habituation process that is influenced by the manipulation of associative variables. Marlin and Miller (1981) and Korn and Moyer (1966) found that preexposure to the startle apparatus lowered the probability and amplitude of the acoustic startle response. Neither group evaluated long-term response decrements following preexposure, but both found no change in short-term decrements.…”

The relation between long-term decrements of the acoustic startle response in rats and the development of freezing behavior during habituation training was examined. Freezing behavior developed over the initial trials of habituation training, and the rate of long-term response decrements was found to be inversely related to the development of freezing. Manipulations (neurological or behavioral) that either reduced the level of freezing or retarded its development promoted startle response decrements. In Experiment 1, rats receiving electrolytic lesions of the ventrolateral periaqueductal gray demonstrated both accelerated long-term startle response decrements and retarded development of freezing behavior. In Experiment 2, preexposure to the startle apparatus (i.e., latent inhibition) accelerated long-term startle decrements and inhibited development of freezing. In Experiment 3, exposure to the startle apparatus following initial habituation training (i.e., extinction) reduced both freezing behavior and startle response amplitudes. The results are discussed in terms of the influence of Pavlovian fear conditioning on long-term habituation of the acoustic startle response.

“…In particular, the US was now considered a complex of tonic and phasic cues, and response decrement to the US was considered to reflect habituation to the context plus habituation to the phasic stimulus (Korn & Moyer, 1966;Marlin & Miller, 1981). However, the increasing relevance ofcontext to habituation reached its zenith in the associative theory of habituation (Wagner, 1976(Wagner, , 1978(Wagner, , 1979.…”

An opaque screen moving overhead elicits an escape response in the crab Chasmagnathus that habituates for a long period after just a few presentations. A series of experiments was performed to determine whether the crab's long-term habituation (LTH) is mediated by an association between contextual cues and the eliciting stimulus, Chasmagnathus failed to exhibit LTH when a visual cue in the experimental environment was changed between training and testing, In addition, long-term exposure to the context in the absence ofthe eliciting stimulus impaired LTH, both when the exposure preceded the habituation training (latent inhibition) and when the exposure came after the training (extinction), Long exposure to the context alone prior to training also produced a decrease in responsiveness to the eliciting stimulus, which confirmed previous results. However, both effects of long exposure were only manifested when the crabs spent a period of time between exposure and testing out of the experimental context. The results of this paper are interpreted as supporting the view that Chasmagnathus LTH can be understood largely by Wagner's associative theory of habituation.

“…Through behaviour, an animal may avoid a disturbance (for example by flying away) or habituate if a stimulus is perceived as harmless (Korn & Moyer 1966). Studies of responses of animals to aircraft have generally involved classifying observed behaviour into categories from non-response to startle (Brown 1990).…”

SUMMARYBehavioural responses of harlequin ducks to military jets were 23 times stronger than their responses to floatplanes, helicopters and military cargo planes, and the significant interaction of aircraft type and noise indicated that noise may be the primary stressor affecting behaviour. A quadratic response of the canonical variable to noise generated from aircraft during standardized 30-minute observation periods was defined. The multivariate analyses were more robust because they indicated covariance in behavioural categories associated with disturbance that was not originally detected in univariate analyses, suggesting the importance of integrating behaviours other than overt responses. The significant effects of military jet over-flights on harlequin duck behaviour emphasize the need to evaluate potential population consequences of aircraft disturbance.
