Relationships between measures of intelligence and choice reaction time

Abstract

This paper draws attention to some of the problems associated with studies of reaction time and intelligence. The experiment reported here used choice reaction time without a home key and was concerned with the relationship between rate of reduction of uncertainty (RRU) and a verbal measure of intelligence (ML) developed for Australian adolescents. Results on a sample of 45 adolescent girls produced a correlation of.20 between RRU and ML. That this measure of intelligence, which has no primary spatial factor, seems to correlate less with RRU than do progressive matrices (SPM) lends support to the view that a common factor other than general intelligence contributes to the correlation between SPM and reaction time. © 1980, The Psychonomic Society, Inc..
