The relation of emotional adjustment to intellectual function—a note.

Distributions of scores on the Wechsler-Bellevue scales and the California Test of Mental Maturity at a V. A. Guidance Center.

“…Harris reports that a study of individual cases "has led to the tentative generalization that within wide ranges of different kinds of personality and behavior problems, and within a wide range of 'cooperation' in the test situation, a measured I.Q. remains fairly stable, even after intensive therapy and improvement in adjustment" (11) The results of the study at the Temple University Center show that veterans rated as psychoneurotics average 3.9 I.Q. points lower than those without such ratings and that both groups are somewhat higher on the performance scale and the mean difference is the same order of magnitude (approximately 3.5 I.Q.…”

Problems of Adolescent Adjustment

“…(15) In the case of intellect and judgment, the lack of growth spurt concomitant with sexual maturation is even more noticeable than in the case of intelligence; since, unlike the latter, not only do these functions exhibit a longer period of chronological growth, but they may also be inversely affected by the emotional instability characteristic of adolescence. (16) Emotional and social growth, on the other hand, seem to follow still another pattern. There is a tremendous initial spurt in response to sexual maturation, which quickly levels off.…”

Intelligence testing and clinical practice.

“…An equally important and common error occurs when the clinical psychologist, in evaluating the results of repeated testing of the same group of patients, misinterprets the phenomenon of statistical regression as changes in the patients' level of intelligence (42). Or suppose the diagnostician attempts to evaluate psychiatric disorder on the basis of a pattern of subtest scores obtained on the Wechsler-Bellevue adult intelligence scale.…”
