Abstract
Two separate experiments confirmed the previously reported finding that, within limits, increasing the duration of a visual target facilitates backward masking. Increasing the target duration has one of two unavoidable results: It decreases the interstimulus interval separating the target from the mask, or it increases the time period from target onset to mask onset. While both manipulations have been reported to facilitate masking, the data of the present two experiments cannot be explained directly by reference to either the interstimulus interval or the target-onset/mask-onset interval.
