Feature-based attention influences later temporal perception

We investigated the influence of feature-based visual attention on later temporal perception. Although there is ample evidence that space-based attention modulates temporal perception, it is not known whether feature-based attention also serves this function. The present study combined a visual selection task with a temporal interval production task to determine whether feature-based attention interacted with temporal perception. The results indicated that temporal perception of visual stimuli depended on whether the same stimulus had been attended to or ignored in a previous visual selection task. The temporal production of previously ignored stimuli was longer than the temporal production of either previously attended to or novel stimuli. This is the first demonstration of the effect of feature-based attention on later temporal perception. We concluded that temporal perception is affected by previously ignored stimuli.
