Influences of categorization on perceptual discrimination.

摘要: Four experiments investigated the influence of categorization training on perceptual discrimination. Ss were trained according to 1 4 different regimes. Subsequent category learning, performed a Same-Different judgment task. Ss' sensitivities (d's) for discriminating between items that varied category-(ir)relevant dimensions measured. Evidence acquired distinctiveness (increased sensitivity are categorized differently) was obtained. One case equivalence (decreased together) found separable, but not integral, dimensions. Acquired within categorization-relevant dimension never either integral or separable The relevance results theories dimensional attention, categorical perception, and discussed.
