摘要
The present research examined the effects of spatially directed attention on the temporal characteristics of information transmission in the visual system. A two-stimulus, two-flash, long-range motion display was used. The results showed that attending to 1 of the 2 stimuli altered the perceived direction of motion, the pattern of motion and no-motion responses, and ratings of motion quality. The results were compared with predictions derived from 2 conceptual frameworks of attention: a temporal-profile model and an additive account. The results supported the temporal-profile model.
