There is evidence that IQ tends to be higher in those who were heavier at birth or who grew taller in childhood and adolescence. Although these findings imply that growth in both foetal and postnatal life influences cognitive performance, little is known about the relative importance of brain growth during different periods of development. We…

Research on the Wechsler Adult Intelligence Scale-Revised and Wechsler Adult Intelligence Scale-Third Edition (WAIS-III) suggests that practicing clinical psychologists and graduate students make item-level scoring errors that affect IQ, index, and subtest scores. Studies have been limited in that Full-Scale IQ (FSIQ) and examiner administration,…

The assessment of hearing impaired children is fraught with a number of problems. These include lack of valid assessment measures, faulty theoretical assumptions, lack of knowledge regarding the functioning of cognitive processes of these children, and biases against these children. This article briefly considers these issues and describes a study…

Elementary school children in three grade groups (Grades K/1, 3, and 5/6) completed either the auditory or the visual 1/9 vigilance task from the Gordon Diagnostic System (GDS) as well as subtests from the Wechsler Intelligence Scale for Children--Third Edition and auditory or visual processing subtests from the Woodcock-Johnson Tests of Cognitive…

Social class, as reflected in socioeconomic status (SES), has such a profound influence on all aspects of performance that it is perhaps the most powerful predictor of academic achievement. Intelligence quotient (IQ) tests in one form or another have been used for quantitative assessment of academic ability since Alfred Binet first developed the…

A study was conducted to collect information on the origins of reading and learning disabilities and on the characteristics of learning disabled children. Data were collected from case histories and evaluation and follow-up reports for 372 learning disabled subjects, aged 6 to 22 years. Characteristics of the subjects were similar to those of…

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),…

The standardized IQ tests which are in use in the schools are scientifically and pedagogically without merit. The construct "intelligence" is a hypothetical notion whose valid expression has yet to be born. IQ tests and the construct of intelligence can be discarded at present, and teaching strategies would be unaffected. To successful teachers…

In an attempt to find a test which minimized cultural bias, three tests were administered to 335 first grade pupils. The subjects comprised 2 groups (123 Anglo children and 212 Spanish surnamed children). The Goodenough Draw-A-Man Test (GDAM) and the Lorge-Thorndike Intelligence Test (LT), Form A, were administered as measures of intelligence. The…

Suggests that until some meaning of innate capacity is included, the word intelligence has little precision separate from its use in a social or cultural context. The culture that evolves its definition of intelligence will identify the tasks that fulfill that definition. (Author/AM)

The Screening Test of Academic Readiness (STAR) and the Peabody Picture Vocabulary Test (PPVT) were administered to 52 kindergarten children to reveal the convergent validity of IQ scores derived from the STAR. The findings raise doubts about the validity of the deviation IQs derived from the STAR. (Author)

Cree and Ojobwa children (N=100) ages 6-15, were administered the WISC. The mean Performance IQ (PIQ) was in the normal range at all ages; the Verbal IQ (VIQ) was in the mentally deficient or dull-normal range. A comparison of Indian IQ norms with original WISC normative data is given. (Author)

Genetic and environmental correlations among 11 Wechsler Intelligence Scale for Children-Revised (WISC-R) subtests were estimated from a sample of 143 twin pairs using the methodology of multivariate behavioral genetics. Correlations due to within-pair environmental influences were generally small, whereas those due to shared environmental…

Analyzed data from standardization sample of 1981 Wechsler Adult Intelligence Scale-Revised (WAIS-R) to determine relationships of WAIS-R intelligence quotients (IQs) to demographic variables upon which sample was stratified. Found significant differences in mean IQs due to race and education level; sizeable differences for occupational groups;…

It has been suggested that IQ's of gifted children resemble parents less than do people in general. This finding may have been an artifact of the particular estimator of the regression coefficient used. An unbiased estimator is introduced and shows that gifted children resemble parents more than persons in general. (Author/RD)
