Title

The Effect Of A Red Background On Location Backward Masking By Structure

Abstract

It has been established that diffuse red light partially suppresses the magnocellular (M) visual pathway. Previous research reported that metacontrast masking is reduced (improved accuracy) with a red background, consistent with a reduction in M pathway response from the mask. In contrast, a recent study used location backward masking by noise and found that accuracy decreased with a red background - theoretically due to suppression of the M pathway's initial localization of the target. The present study provides the first report examining the effect of red light on performance in a location backward masking by structure task. Results revealed a main effect of a red (as opposed to a green) background on reducing masking (improved accuracy) with a medium effect size (2 = .23). This effect was strongest at the 47- and 60-msec stimulus onset asynchronies. Results suggest that red light primarily decreases interference from the mask in location backward masking by structure.
