Visual search for a target, orthogonal to distractors (nontargets) in orientation, has been shown to be independent of the number of distractors (set size). This finding has been thought to indicate that the search occurs spatially in parallel and without capacity limitations. The current study was designed to test whether an orientation difference of 90 degrees between the target and distractor gratings would produce a set-size effect when performance was measured at contrast threshold, that is, whether the threshold contrast at which the target was detected among distractors increased as a function of the number of distractors. The second question studied was whether signal-position uncertainty could explain the possible set-size effect.
