A further test of the superposition model for the redundant-signals effect in bimodal detection

Abstract

The superposition model proposed by Schwarz (1989) to account for the redundant-signals effect in a bimodal detection task with visual and auditory signals is tested further. It is shown that the model does not fit the observed standard deviations reported by Miller (1986) if the residual (motor) component is assumed to be independent of the waiting time. © 1991 Psychonomic Society, Inc.
