Investigated the validity of the Luria-Nebraska Intellectual Processes Scale (IPS) as a substitute for the Wechsler Adult Intelligence Scale (WAIS). IPS scores were correlated with the three WAIS IQs, and regression equations were computed to obtain estimated Verbal IQ, Performance IQ, and Full Scale IQ. (Author)

We evaluated the predictive accuracy of short forms of the Wechsler intelligence scales for individuals with high functioning autism. Several short forms were derived from participants who had received the full procedure. Stepwise multiple regression analyses were performed to determine the strength of association between the subtests included in…

Twenty-four measures of crystallized intelligence and fluid intelligence were obtained for samples of graduates and failures of an innovative instructional setting where computer-managed mastery learning was implemented to teach elementary electricity and electronics. Results suggest that some unconventional educational environments are not…

A correlation matrix of 21 structure-of-intellect (SOI) tests taken by 204 Marine officers at a military base in Southern California, which was intended to reflect aptitudes for military leadership, was reanalyzed through exploratory factor analysis and confirmatory maximum likelihood factor analysis. Higher order factors appeared to have…

Drawing tests are often used to provide confirmatory and supporting evidence of intelligence or intellectual functioning. The relationship between scores on these types of instruments and academic achievement was studied among graduate students seeking degrees in education. The sample consisted of 125 graduate students in education (93 women and…

This study investigated correlations between the Qualitative score of the Porteus Maze Test and age and rates of recidivism of correctional institution inmates. In addition, the study was structured to provide answers to the following questions: (1) Is there a relationship between age and rates of recidivism and the Conformity-Variability score of…

Three tables are provided to aid in the clinical interpretation of factor scores for the Wechsler Adult Intelligence Scale-Revised (WAIS-R; 1981). The factor structure of the WAIS-R has proven to be robust across samples, tests, time, statistical analyses, measurement scales, and distortions of the distribution. Information necessary to make…

Tests of intelligence and structured measures of emotional status, aptitudes, and achievement alone do not suffice in predicting the vocational adjustment of the mentally retarded. Since the main concern is the evaluation of the many aspects of behavior which make the individual a unique and changing person, a format was developed which included a…
