*Test Reliability

The psychometric utility of six experimental cognitive style (CS) measures was analyzed. Examinees were 1,135 clients of the Johnson O'Connor Research Foundation who, during 1985, completed at least one of the six CS tests. Information is provided on measure reliability; relationships among CS measures; relationships with standard battery aptitude measures; and relationships to sex, age, education, and laterality. Measurement precision appears adequate for the Rod-and-Frame Test and the Matching Familiar Figures Test style score. For the Stroop Color and Word Test, the reliability was a little low but could be raised by lengthening the test. These three measures appear to be independent of each other and of the standard battery measures and may be useful additions to the battery if further research indicates that they predict vocational/avocational performance. The Verbalizer/Visualizer Questionnaire requires further investigation and development prior to use. The measure of global-analytic style did not have adequate reliability, and the measure of global-analytic ability showed overlap with current battery measures, but might prove useful as a measure of general reasoning ability. Item statistics, the calculation routine for over- and under-correction on the Rod and Frame Test, and descriptive statistics for the standard battery measures are appended.
