Previous research suggests that visual motion perception can be spared from metacontrast masking [Kolers, P. (1963). Vision Research, 3, 191-206]. Here, we confirmed that detection of visual rotation is spared to a larger degree than detection of visual shape (Experiment 1) and that even shapes of masked stimuli can be detected if the shape-detection task is easier (Experiment 2). Implications of our findings for the conclusion that performance in masked priming studies depends on processing of non-conscious inputs are discussed. (C) 2007 Elsevier Ltd. All rights reserved. |
