Analysis of Test-Retest Reliability for a Battery of Cognitive Speed Tests
Abstract
There has been almost no increase in the predictive validity of traditional psychometric tests since they were first put into use more than 60 years ago. Recent developments in the cognitive and computer sciences, such as computerized tests of cognitive (mental) speed, appear to have considerable potential for adding incremental validity to existing aptitude batteries. Little is known, however, about the psychometric characteristics of many of these newer measurement techniques. The purpose of the present study was to determine the reliability (in particular, test-retest) coefficients for a battery of microcomputerized cognitive speed tests. In addition, the validity of such tests was explored. A set of four reaction time tests, three inspection time tests, and an experimental test of speed of processing in active memory were administered to 104 male and female college students between 18 and 35-years of age. Seventy-four subjects returned for retesting with 10 days. In addition, all subjects were given a battery of group administered criterion tests. Their scores on the Scholastic Aptitude Test (verbal and math), as well as their high school and freshman grade point averages, were recorded from their official university transcripts.
