Summary:
The orienting response is hypothesized by Sokolov (1963, 1969) to be monotonically related to the magnitude of stimulus change and independent of the direction of change. These parameters were simultaneously manipulated in the present study along the dimension of stimulus frequency. The intermediate repetitive standard stimulus was a 1000 Hz tone and the infrequent deviant stimuli were 950, 975, 1025 and 1050 Hz tones. The component of the human evoked potential found to be the most sensitive to stimulus deviance was the P3. Consistent with Sokolovian theory, P3 amplitude displayed a U-shaped function in which the extreme deviants produced the largest P3s, proximate deviants produced intermediate P3s and the repetitive standard produced the smallest P3s.
