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)

The test-retest reliability and predictive validity of developmental quotients (DQs) derived from the Cattell Infant Intelligence Scale was assessed with 83 children with mental retardation, age 30 months or more. Scores were impressively stable on retest. DQs derived from the Bayley Scales of Infant Development were superior to Cattell DQs in…

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…

Data from the Wechsler Adult Intelligence Scale-Revised (WAIS-R), grade point average (GPA) after 2 semesters of full-time enrollment, and selected student characteristics were compared for 49 learning-disabled college students. WAIS-R results were not generally predictive of academic success, although Comprehension and Similarities subtests…

THE RELATIVE EFFECTIVENESS OF TASK SCORES VERSUS IQ AS PREDICTORS OF ACADEMIC ACHIEVEMENT WAS INVESTIGATED, AND THE CORRELATIONS BETWEEN TASK SCORES AND IQ RE-EXAMINED. SUBJECTS WERE 99 UPPER-MIDDLE CLASS ELEMENTARY SCHOOL CHILDREN WITH A MEAN STANFORD-BINET IQ OF 126 (SD EQUALS 19). THE INSTRUMENTS USED WERE DUNN'S OBJECT SORTING TASK (OST),…

This study evaluated interrelationships among the scores of 51 high school seniors on the Remote Associates Test (RAT), verbal subtests of the Torrance Tests, the Alpha Biographical Inventory (ABI), and IQ. For all subjects, RAT scores, IQ, and the ABI Academic Success score comprised an interrelated "intelligence cluster." With males, none of the…

This study sought to determine the appropriateness of two conventional intelligence tests for assessing the ability of economically deprived young adults participating in job training programs by comparing their test results with those of the test standardization groups. The Wechsler Adult Intelligence Scale (WAIS), and the Langmuir Oral Direction…

Reviews findings on the predictive validity of psychometric tests of intelligence. Concludes that conventional tests of intelligence can be useful but only if they are interpreted very carefully, taking into account the factors that can affect them, and in conjunction with other measures. (Author)

Six current issues in the use of tests are examined in this paper. Are the tests used in education valid? In general and to a reasonably satisfactory extent they are. Is the emphasis these tests place on cognitive achievements a serious limitation? Because of the basic and pervasive role of cognition in human affairs, and in the absence of any…

The learning potential (LP) procedure represents an alternative method of measuring ability of Spanish-speaking students who tend to score low on traditional IQ tests. This study sought to determine the relative predictive power of LP and IQ measures on achievement of 188 first through sixth grade Spanish-speaking students. Subjects participated…

A pilot study was conducted to ascertain if creative abilities measures could be adapted to the upper elementary school level and maintain their factorial validity. The factorial validities of seven measures of productive thinking abilities at the upper elementary school level were tested across grade levels and different socio-economic…

This book addresses the question of what tests are measures of. Intelligence, achievement, and personality tests not based on empirical investigation have questionable validity. Some researchers now suspect that almost all tests given to students in all subjects, as well as general tests of intelligence and personality, are essentially language…
