WISC and Nebraska performance of deaf and hearing children

The purpose of this study was threefold: (1) to evaluate the visual-perceptual skills of deaf and of hearing children; (2) to compare the performances of the two groups on two tests frequently used to assess intellectual functioning; and (3) to compare the performance of deaf children in a day school with those in a residential school. Results indicate deaf children are not inferior to hearing children on visual-perceptual tasks and day-school deaf children performed better than residential deaf children. Differences between the deaf and hearing on the two tests were significant on 3 of the 10 subtests. In addition, normative scores on at least one subtest of the Nebraska appear too high, and correction may be in order. Correlations between the two tests, for both deaf and hearing children, were low.

Validity of Koppitz's developmental score as a measure of organicity

The Koppitz developmental score was used to evaluate the Bender Gestalt performances of 30 children with, and 30 children without, brain damage The brain-damaged children had a higher mean score than the non-brain-damaged Ss and did more poorly relative to the normative data reported by Koppitz.

Comparison of two sociometric devices for measuring personality integration

A comparison was made of two sociometric measures of personality integration. Contrary to prediction, the more brief, 6-item PIRT scale was significantly more reliable ( r11 = .84) than the lengthier 30-item ESD scale ( r11 = .74). Also contrary to prediction, neither test was more highly correlated than the other (and therefore more valid) with any of 8 construct-validity measures. It was concluded that the PIRT was the more functional measure and therefore recommended for use in future personality integration research. Earlier results concerning the relationship of personality integration to self-concept and environmental contact, as well as locus of control and locus of evaluation in college-age females, were replicated.

An expanded sociometric device for measuring personal effectiveness

158 male and 80 females representing 4 fraternities and 3 sororities at a large state-supported university in the Southwest were administered Duncan's Personality Integration Reputation Test and 48 additional sociometric items. on the basis of their content validity and correlation with Duncan's scale, 30 of the 48 items were selected for a test of personal effectiveness. The correlation of the total of these 30 items with Duncan's scale was .92 for males and .90 for females. The 30 items plus 6 from Duncan's scale, gave similar rs (.93, .91). The major advantage of the new scale lies in greater appeal to users who might be prejudiced against a 6-item instrument. Estimates of reliability and validity are needed.

Reliability of Duncan's personality integration scale

Investigations were conducted to determine the reliability of Duncan's Personality Integration Scale. The two types of reliability investigated were test-retest stability and intersex congruence. The results indicated that Duncan's Scale possesses test-retest reliability for both male and female populations but lacks intersex congruence.
