| Abstract: | Examined the habituation of fright and arousal responses of the goldfish and roach to the repeated operation of a plunger in the water. The early response was fright, which habituated, and then the response characteristic of arousal appeared, which habituated as well. Longer intervals between stimuli required more presentations of the stimulus for habituation to occur in goldfish. Roaches required more presentations of the stimulus than goldfish for the responses to habituate, and telencephalic ablation severely impaired habituation of arousal, though not fright responses. Results are discussed in relation to recent work on arousal, habituation, and telencephalic function in fish. (25 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved) |
