Visual signal detection. I. Ability to use phase information.
We present experimental evidence that humans use phase information for detection and discrimination of visual signals (static sine waves) when sufficient a priori information is made available. Under these conditions human performance exceeds that of the best-possible phase-insensitive detector. There is a marked reduction in performance when signal-phase information is not given to the observer.
