When searching for a "pop-out" target, interference from salient but irrelevant distractor can be reduced or even prevented under certain circumstances. Here, five experiments were conducted to further our understanding of three different aspects top-down reduction: first, whether not qualitatively search modes account reduction patterns; second, practice plays causal role in reduction; and third, how specific is, that by intradimensional distractors as effectively cross-dimensional distractors. The results provide evidence does critically depend on the implementation feature mode, rather with distractor, acquisition an effective suppression strategy. In addition, they suggest is based hierarchically organized weighting ("dimension weighting"), than completely independent weighting.
