The subjects used in the present study were undergraduate students enrolled in lower division psychology courses. The sample consisted of 40 students (25 females, 15 males). The SIT and the SILS were administered individually to each subject with a 45-day interval between the first test and the retest on both instruments. The correlation coefficients were computed by use of the Pearson product-moment technique. The correlation between SIT IQ scores and SILS raw scores derived from the initial testing was .46. An analysis of the results of the second testing between the same instruments revealed a coefficient of .54. Test-retest reliability coefficients of .83 and .80 were obtained for the SIT and SILS measures. All four coefficients were significant beyond the .01 level
