Abstract
The galvanic skin response (GSR) component of the orienting reflex was recorded for four groups of 12 Ss each. They were given 10 habituation trials to black on white numeric stimuli presented in seriatum. On Trial 11 an out-of-sequence test stimulus (TS) was delivered and was followed by one additional in-sequence number. The TS was either ±1 or ±11 places out of sequence. It was found that GSR magnitude to the TS was primarily a function of the amount of disparity provided by the TS, irrespective of the direction of that disparity. Dishabituation to the subsequent in-sequence stimulus was not, however, clearly present. The results were related to Sokolov’s neuronal model of habituation and to previous research.
