Involuntary attention with uncertainty: peripheral cues improve perception of masked letters, but may impair perception of low-contrast letters.

Abstract

Improvements of perceptual performance following the presentation of peripheral cues have been ascribed to accelerated accrual of information, enhanced contrast perception, and decision bias. We investigated effects of peripheral cues on the perception of Gabor and letter stimuli. Non-predictive, peripheral cues improved perceptual accuracy when the stimuli… (More)
