Abstract: | The hypothesis that reaction times are positively associated with intelligence was tested on 444 nine-year-old Japanese children. Intelligence was measured by the Raven's Standard Progressive Matrices, and 12 reaction time parameters were obtained to give measures of movement times, reaction times proper (decision times), differentiated into simple and complex reaction times, and variabilities. Factor analysis of the reaction time tasks indicated the presence of a general factor and three primary factors identifiable as movement times, simple reaction times, and complex reaction times. Of these, only complex reaction times showed significant associations with intelligence. |
