STIMULUS CHANGE PROPERTIES OF THE RT READY SIGNAL.

Abstract

Two studies tested the generality of the Perkins-Logan hypothesis in the reaction-time experiment. Both studies used a parametric design with four ambient (intertrial) intensities of white noise ranging from 0 to 90 dB in all combinations with the same four intensities used as ready signals. Direction of change (increase or decrease) from the ambient intensity was significant in one of the two studies, but magnitude of change (30, 60, or 90 dB) produced a highly significant effect in both studies.
