A shadow moving overhead acts as a danger stimulus and elicits an escape response in the crab Chasmagnathus granulatus, that habituates after 15 stimulus presentations at 3-min intervals. Here, the habituation was induced by 3 diverse shadow stimuli and the habituated response persisted after 24 hr in every case. This long-lasting effect failed to appear if the testing stimulus did not keep the same spatial specificity as that of the training one. A partial stimulus generalization was detected… CONTINUE READING
