In this preliminary investigation of variability of responses on the Lüscher Color Test, subjects were 567 volunteers administered the test twice with a 10-min. interval between them. Two hypotheses were tested: (a) that variability of responses attests to the personality of the respondent (tested by the relations of variability and MMPI scale scores), and (b) variability of responses is based on learning the test's content. As such, men's scores should be more variable than women's. Analysis showed that variability was not correlated with scores for personality on the MMPI scales. Men's scores are more variable than women's, but only until age 45.
