Abstract

Change-detection necessitates comparison of visual working memory (VWM) representations with perceptual inputs (Hyun, 2006). The current study tests masking interference with consolidation of test items being compared with sample items in memory. Subjects performed a change-detection task where they were asked for reporting a color change between two sets of colored boxes. In masking trials, complex pattern masks were presented at each item position 17ms after the test display disappeared. Change-detection performance was worse in masking trials than no-masking trials, and Event-related potentials (N2pc) was virtually absent when masks were present. The interference effect observed both behaviorally and electrophysiologically supports for the presence of a comparison process between memory and perceptual inputs.
