Perceptual rhythms by phase-aligned perceptual performance peaks across trials (opens in new tab)

Perceptual processing may rhythmically alternate. There is a line of evidence from dense sampling psychophysics supporting this claim: In such studies, performance in visual target detection or discrimination is repeatedly tested at various fine-grained time intervals relative to a reference event. This reference event is presented at the beginning of each trial, and it is thought to reset some internal oscillation. Performance time courses following the reset often show rhythmic oscillations...
