The reliability and predictive validity of the WISC-R was investigated with 46 Mexican-American children. Approximately a year and a half after the administration of the WISC-R, scores on the Iowa Tests of Basic Skills were collected. Results indicated that the WISC-R meets minimum requirements of reliability and predictive validity with…

The cerebral laterality of children with various configurations of verbal-performance discrepancies was inferred with an objective measure of lateral preference using Verbal and Performance IQ scores of the WISC-R. Results were interpreted as lending support to the notion of competition antagonism between cortical hemispheres and a possible…

The most striking aspect of this study is that the PIAT, designed and standardized for children in the educational mainstream, is as applicable to Mexican-American children as to their Anglo counterparts. Consequently, the PIAT may be advantageous as a screening instrument with this culturally specific population. (Author)

The present study examined the reliability of the WISC-R subtests and IQ scales when administered to Mexican-American children. In an effort to extrapolate these findings to the individual child, this study also attempted to ascertain the standard errors of measurement for each subtest and IQ scale. (Author)

Experimental results indicated that verbal intelligence was the best predictor of childrens' overall performance on a paired-associate learning task. Teachers' ratings provided a surprising degree of predictive efficiency for abstract recall which was redundant with verbal intelligence. (Author/JAC)

The validity and reliability of the Peabody Picture Vocabulary Test was estimated with emotionally disturbed adolescents. Results indicated that the power of the test to predict future achievement of emotionally disturbed adolescents is comparable to that expected for normals. (Author)

Investigated personality dimensions concomitant with learner's cognitive rigidity. Results indicated the personality dimensions of tenseness, compulsivity, group dependency, absent-mindedness, sensitivity, and emotional stability explained 36 percent of the variability in subjects' increasing levels of cognitive rigidity. Showed a pervasive use of…

Under realistic individual testing conditions there is consistency between the factor structure of the Wechsler Intelligence Scale for Children-Revised (WISC-R) with Anglo and bilingual Mexican American children. This investigation failed to indicate any unfairness to the Mexican American child on the WISC-R. (Author)

Experienced and preservice teachers agreed about the importance of the school psychologist and the appropriateness of referral problems. Analysis of ratings revealed that experienced teachers had a more negative opinion of the school psychologist's functioning when compared to their novice counterparts. (Author)

The laterality preference patterns and types of oral reading errors were examined for seventh-grade males. Results support the initial argument that difference-poor readers fail to comprehend because of problems in organizing visual input, which seems intimately tied to a bilateralization of functions.

The behavior of preadolescent males was rated by two teachers using the Devereux Child Behavior Rating Scale. Interrater teacher reliability estimates were not significantly different than those reported with mental health professionals, but differentiated significantly between diagnostic categories. (Author)
