The validity of the Rorschach for assessing cognitive and affective changes.

Exner's (1985) Rorschach norms of children 5 to 16 years old were used to test predictions based on developmental theory, previous cognitive studies, and Achenbach and Edelbrock's (1981) norms on behavior problems in children. In the cognitive realm, the Rorschach scores reflected the predicted increase in complexity, integration, and precision of thinking; richness of ideas; conformity to socially acceptable ways of thinking; and the concomitant decrease in unrealistic, egocentric ideas. In the affective realm, the Rorschach scores reflected the predicted decrease in uncontrolled expression of affect, increase in controlled expression of affect, and increase in inwardness. However, the Rorschach scores failed to reflect the predicted decrease in anxiety and increase in depression. Finally, there was no evidence of increased accuracy of perception.
