The Right

Subjects identified which of two target letters was presented when the target was accompanied by a similar or dissimilar noise letter, the target appeared on the right or left of fixation, and the target was central or peripheral to the noise letter. Although performance deteriorated in the presence of noise letters compared to control conditions, masking was no greater with similar than dissimilar noise letters. Rather masking effects were specific to particular target-mask pairs, suggesting facilitation of target perception when mask and target shared features critical to the target-discrimination task. Thus, no evidence for Estes' interactive channels model was obtained. Neither the left vs right position of the target nor its centrality had any effect on accuracy or speed. Correct latencies to a target covaried with its accuracy of detection, but incorrect latencies were more strongly associated with the target identified than with the target presented.
