Light intensity and judged duration

Abstract

Judged duration as a function of stimulus intensity was studied for both audition and vision, with loudness and luminance output equated. More intense sounds and lights were judged longer than less intense auditory and visual durations, and this intensity effect was greater for vision. The judged-duration/stimulus intensity relationship appears to represent as stable a psychophysical phenomenon as the fact that judged intensity grows as a function of stimulus duration. © 1978, The Psychonomic Society, Inc..
