Matching the rate of concurrent tone bursts and light flashes as a function of flash surround luminance

Abstract

Subjects adjusted the rate of a repeating toneburst to match that of a concurrently flashing light, or vice versa. Flashes were viewed in luminous or wholly dark surrounds. Matches usually departed from veridical rate matches, and always were affected in the same direction by changes in surround luminance. Matches were a function of whether subjects controlled the visual or auditory stimulus; also, subjects usually reported "driving" of flash rates by auditory rates when they controlled tone rate, but not when they controlled flash rate. © 1981 Psychonomic Society, Inc.
