Paracontrast and disinhibition

Effects of contrast polarity in paracontrast masking.

The visibility of a target stimulus can be suppressed (inhibition) or increased (facilitation) during paracontrast masking. Three processes have been proposed to be involved in paracontrast masking: brief inhibition, facilitation, and prolonged inhibition (Breitmeyer et al., 2006). Brief inhibition is observed when the mask precedes the target at short stimulus onset asynchronies (SOAs) ranging...

Disinhibition in pitch memory

Recognition of the pitch of a tone is disrupted by the interpolation of other tones during the retention interval. The disruptive effect of an interpolated tone varies systematically as a function of its pitch relationship to the tone to be remembered, and is maximal at a ⁄3-tone separation. When such a tone is interpolated, the interpolation in addition of a further tone that is ⁄3 tone remove...
