The relationship between hearing disorder and performance on intelligence tests among 28 children and young adults with Down Syndrome was investigated. Performance on intelligence tests by individuals with abnormal tympanograms was inferior to that of individuals with normal tympanograms. Hearing sensitivity measures were uncorrelated to…

Learning Disabled children (N=198) were tested on both the WISC-R (Wechsler Intelligence Scale for Children-Revised) and K-ABC (Kaufman Assessment Battery for Children). Joint factor analysis produced three-factor and four-factor solutions. Factors corresponding to three K-ABC scales generally converged with three WISC-R factors. (Author/CL)

The relationship between forward and backward digit span and basic cognitive processes was examined. Subjects were administered measures of sequential processing, simultaneous processing, and planning. Correlational analyses indicated the serial processing character of forward digit span, and the relationship between backward digit span and…

Illustrates a method for generating continuously adjusted age norms using the normative data for the Wechsler Adult Intelligence Scale-Revised (WAIS-R). Specific procedures for calculating age-adjusted Verbal, Performance, and Full Scale IQ scores also are demonstrated, with a worked example. Comparisons show continuous norming scores are more…

Reviews the effects of vision changes on intelligence and explains how intellectual performance may be improved by attempting to compensate for vision loss. Suggests that vision factors can't be ignored when assessing intellectual changes and may account for a large portion of mental impairment previously ascribed to other factors. (JAC)

Examined the level of perceptual differentiation of 42 young adult drug addicts. Analysis of variance showed that addicts, like alcoholics, were less perceptually differentiated than normals. Correlational and/or multivariate procedures yielded significant relationships between differentiation, verbal and abstraction abilities, likelihood of…

Administered the Wechsler Intelligence Scale for Children, Wechsler Intelligence Scale for Children-Revised, and Wechsler Preschool Primary Scale of Intelligence in a counterbalanced design to randomly selected elementary school children (N=72). Results indicated that the verbal Intelligence Quotients (IQs) were comparable, but the performance and…

Samples in research on individual and group differences may be selected based on whole scores which differ from the population mean. Children are diagnosed in clinical practice with a whole score. These procedures produce regression to the population mean which can affect accuracy and adequacy of part score interpretations. (Author/DWH)

Examined the relationship between the Peabody Picture Vocabulary Test-Revised (PPVT-R), the Peabody Picture Vocabulary Test (PPVT) and the Wechsler Intelligence Scale for Children-Revised (WISC-R) with incarcerated delinquents (N=35). Results indicated that the PPVT-R yielded a higher correlation with the WISC-R verbal IQ scores than did the PPVT.…

Acknowledges a number of studies that show an association among children, but warns that such an association does not prove causality. Calls for the implementation of such controls as IQ and social class in research on the effects of television on achievement. (GC)

Argues that if a testing situation is not similar to situations in which a child regularly performs linguistically, the test's ecological validity is compromised and its results must be viewed skeptically. (FL)

Discusses how the power and potential of the computer may shape the classroom of the future by presenting a scenario of a classroom in the year 2001. The role of artificial intelligence in this environment is considered. (JN)

To determine cross-sectional similarity of the underlying structure of classroom environment variables, the Learning Environment Inventory and Primary Mental Abilities Test were administered to 46 eighth grade classes and 50 eleventh grade classes. Structures of affective and cognitive variables became very similar, however, a slight…

This study compares an entire population (78) of high school discipline problem students with a control group of students who were not involved in acts of misconduct. Significant differences were found to exist in intelligence, scholastic achievement, scholastic abilities, vocational aptitude, and personality characteristics in elementary school.…

The Rorschach was given to 60 school children in two designs: chronological age (CA) and mental age (MA) orthogonal and CA=MA. Responses were scored for Form Accuracy, Complexity, Movement and Friedman's Developmental Level (DL) Scoring System. The results suggest that the DL system does assess MA independently of CA.
