A significant recognition of ignored nontarget was demonstrated in a task which stressed perceptual intentions of processing an unfamiliar shape (H.-J. Kim & J.-O. Kim, 2010; H.-W. Cho & J.-O. Kim, 2010). This result was accounted for by a residual capacity hypothesis which proposes that when processing the target leaves residual capacity, the structure of the nontarget might be described. An alternative hypothesis argues that failure of attention control of the target contributes to recognition of the nontarget. Using a set overlapping shapes of a target with two nontargets, two experiments examined predictions derived from competing hypotheses. Two experiments demonstrated a superior recognition of identical nontargets over that of different nontargets. These results provide a strong support for the residual capacity hypothesis.
