Abstract:
Restricting the encountered range of stimuli on a particular stimulus dimension changes a person's perceptual frame of reference, or adaptation level, for such stimuli. The present experiment explores the effect of stimulus avoidance on perceptual adaptation and subsequent avoidance. Results converge with previous findings to indicate that avoidance of danger signals reduces perceptual adaptation level for those signals. In the present experiment, subjects first avoided high-pitched danger-signal tones, thus restricting the range of tone stimuli they encountered, and subsequently overestimated the pitches of low-pitched safety-signal tones. They consequently avoided the low tones as if they were high-pitched danger signals. Perceptual adaptation was evident in subjects' tone pitch ratings only if they had rated the tones throughout their avoidance trials.

Avoidance Learning and Learned Helplessness
Avoidance learning occurs when an organism learns that a specific behavior can prevent an unpleasant outcome. For example, a student who receives a bad grade may start studying harder to avoid future poor grades. This behavior persists even when the negative outcome is no longer present. Avoidance learning is powerful because it maintains behavior in the absence of the...
