Reduction coding in responding to signal sequences

Abstract

"Using a 5 X 5 matrix of lights and a similar panel of push buttons, five Ss were required to respond to sequences of 60 signals presented in subsequences of two, three, or four signals per group with intervals of .37, .52, .68, or 1.02 sec. between items. Performances… were compared with a self-paced condition… ." All 12 experimental conditions were inferior to self-pacing speed and accuracy, except the 2-signal .37-sec. interval condition, which was faster in terms of total transmission time and rate of information transmitted. "It was concluded that… coding by groups can, under limited conditions, result in performance… superior to… self-pacing… ." (PsycInfo Database Record (c) 2025 APA, all rights reserved)
