Abstract
The effect of selective adaptation by end-point stimuli on a synthetic/bi-di/continuum was investigated in terms of the change in masked recognition thresholds for stimuli within the continuum. Adaptation with either/bi/or/di/produced typical shifts in the identification boundary, while adaptation only with/bi/ produced shifts in the ABX discrimination peak. Both adaptors also produced significant decreases in the recognition threshold of all stimuli within the non-adapted category and, for the/di/ adaptor, reduced thresholds also for the adapted category. These results cannot be explained by assuming the action of only a simple, single factor such as fatigue, stimulus contrast, or response contrast.
