Abstract

Previous research on visual contingent aftereffects has been concerned with examining the effects of various parameters (e.g., spatial frequency and luminance) on the adaptation to, and decay of, contingent aftereffects. The current study tested the viability of using visual contingent aftereffects in a display context. Using established characteristics of contingent aftereffects, a program of contingent aftereffect adaptation was designed. Studies were conducted with 24 college students to determine whether Ss who were adapted to see visual contingent aftereffects invoked by a visual display could achieve more rapid or certain identification of a display under low luminance conditions. Results confirm that (a) contingent aftereffects can improve performance on a visual discrimination task requiring information from a display and (b) contingent aftereffects are more enhanced at low levels of illumination.
