Comparison of the home environments provided by 38 low-income mothers with IQs less than 75 and 27 low-income mothers with IQs over 85 found significant differences, indicating greater developmental risk for children of low IQ mothers resulting from environmental deprivation. Most of the variance was in the area of interaction. (Author/DB)

This comparison of regression discrepancy model results for learning disability identification used published IQ-achievement and reliability coefficients and generic, mean values. Use of mean IQ-achievement values resulted in higher discrepancy rates for a clinical sample. Use of both mean IQ-achievement and reliability values resulted in higher…

Estimated age-adjusted Wechsler Adult Intelligence Scale-Revised intelligence quotient (IQ) scores using linear regression techniques and continuous norming of two samples of psychiatric inpatients (total N=150) in Veteran's Administration hospital. Results support use of estimation procedure in clinical and research settings desiring brief but…

Comparisons of Wechsler Intelligence Scale for Children-Revised scores, for 24 children with learning disabilities demonstrating a low verbal, high performance intelligence quotient (IQ) discrepancy and 33 slow learning children having uniformly low verbal and performance IQs, revealed few cognitive differences beyond the Performance Scale…

Intelligence quotient (IQ) differences among groups according to sex, and demographic and other variables have been explored for a variety of intelligence tests. This investigation analyzed data from the standardization sample for the 1981 Wechsler Adult Intelligence Scale-Revised (WAIS-R) to determine the relationship of WAIS-R IQs to the…

Multiple regression analyses on data from 421 children indicated that mother's use of more than 1.5 ounces (approximately three drinks) of alcohol per day during pregnancy was significantly related to average IQ decrement at four years of age of almost five IQ points even after adjustment for numerous variables. Readers cautioned against using…

This article argues for the adoption of a 2-step procedure in diagnosing dyslexia: first, identify students with word list reading standard scores below 90, and then identify students with a reading score at least 10 points lower than expected from the full scale intelligence quotient. (JDD)

A study designed to examine biological, sociological, and early maturational correlates of intelligence collected data prospectively, from birth to 15 years of age, on a sample of 987 black children. Multiple indicators of eight independent and three dependent variables were tested in a structural equation model. Altogether, clear sex differences…

Patterns of sensory abnormalities in children and adults with autism were examined using the Diagnostic Interview for Social and Communication Disorders (DISCO). This interview elicits detailed information about responsiveness to a wide range of sensory stimuli. Study 1 showed that over 90% of children with autism had sensory abnormalities and had…

The effect of level of stereotypy on learning a discrimination was examined using a factorial design with high and low levels of stereotypy and three levels of IQ with 30 institutionalized retarded persons. Results indicated the effects of stereotypy were different across the IQ levels. (Author/DB)

Administered three Wechsler adult intelligence scales to 72 undergraduates and tested the quality of means, variances, and covariances, utilizing subtest scale scores and IQs. Results indicated that the three scales were not parallel. Generally, the subtest scaled scores exhibited less similarity across the three scales than the IQ estimates.…

Word recognition data from identical and fraternal twins and siblings (N=172) indicated that the phonological coding deficit of children with reading disabilities was highly heritable. Orthographic coding was not significantly heritable. Poor readers with low IQs were superior to similar reading but average IQ readers in phonological coding.…

Concurrent validity testing of the Slosson Intelligence Test-Revised with the Stanford-Binet Intelligence Scale (Fourth Edition), involving 191 individuals (ages 5-69 and IQs of 36 to 110), found a high correlation between the two scales. However, the Slosson unsatisfactorily matched the Stanford-Binet's assignment of individuals to IQ categories.…

The study with noninstitutionalized organic and familial mentally retarded and borderline mentally retarded children (N=79) at 2 chronological age levels (mean ages 7 and 10) found no age differences in imitation behaviors in the organic low IQ group and more absolute imitation and recall behaviors in familial low IQ children. (Author/DB)

Within a longitudinal design, the present study assessed parental attitudes, quality of stimulation in the environment, historical factors, and children's temperament to identify determinants of cognitive ability at 54 months. Children (n=147) were randomly assigned to one of three treatment groups: a center-based intervention, a home-based…
