title: Cerebral asymmetry in the perceived duration of color stimuli.
abstract: 20 right-handed males judged the duration of small and large colored circles, which were briefly exposed in the left, center, and right visual fields. Perceived duration was a logarithmic function of exposure duration and a positive function of size and chromaticity. Over-all accuracy was equivalent in the left and right visual fields, but the effects of chromaticity and duration on subjects' judgments were asymmetrical. These and other findings suggest a two-process model of time perception in which there is right hemispheric control over a visual information processor and left hemispheric control over a timer.
