The relationship of the Watson-Glaser Critical Thinking Appraisal to sex and four selected personality measures for a sample of Dutch first-year psychology students.

In reaction to an earlier publication by A. Simon and L. O. Ward (see record 1975-26421-001) on the 1952 version of the Watson-Glaser (W-G) Critical Thinking Appraisal, the present study examined the relationship of the 1964 forms of the same instrument to 4 selected noncognitive measures for a sample of 190 undergraduates. Except for Subtest 5, Evaluation of Arguments, subtest and total score means were significantly lower for Form ZM than for Form YM. Reliabilities of the subtests ranged from only .22 to .69. Total score reliability estimates, however, were .72 (ZM) and .77 (YM). No sex differences were found. The correlation between the W-G total scores and those on the extraversion-introversion measure was not significant. Correlations of the W-G measure with other personality characteristics (neuroticism and rigidity) were also close to zero. As for version ZM of the W-G measure, the performance was significantly associated with test-defensiveness. (
