Choice reaction time and simple reaction time were measured for 147 young adults for whom significant positive correlation between nerve conduction velocity in a brain nerve pathway and nonverbal intelligence was previously found. Results suggest that two largely independent neurophysiological processes affect intelligence. Differences in choice…

The standardization samples for the American Wechsler Intelligence Scale for Children-Revised (WISC-R) (n=2,200) and the French WISC-R (n=1,066) were used to compare the intelligence of French and U.S. children. The American sample scored higher on verbal IQ, full scale IQ, and some subtests. Implications of results are discussed. (SLD)

Correlations and mean score differences between IQs derived from the Universal Nonverbal Intelligence Test (UNIT; Bracken & McCallum, 1998) and the Wechsler Intelligence Scale for Children-Third Edition (WISC-III; Wechsler, 1991) were compared. Participants were Limited English Proficient (LEP) Mexican-American elementary school students, who…

An auditory inspection time (AIT) test, pitch discrimination tests, and verbal and non-verbal mental ability tests were administered to 59 undergraduates and 119 12-year-old school children. Results indicate that AIT correlations with intelligence are due to AIT being an index of information intake speeds. (TJH)

Twenty children, aged six-eight, with normal nonverbal intelligence but language comprehension deficits, were administered tasks of verbal and perceptual proportional analogical reasoning and a problem-solving task of functional analogical reasoning. Compared to controls, subjects were deficient in analogical reasoning. However, when the…

This longitudinal study examined the hypothesis that two different types of joint-attention skills were related to verbal and nonverbal IQ measures through middle childhood. Subjects were infants born preterm and tested at 13 months and at 8 years. Findings provide support for the hypothesis that the initiation of joint attention makes a unique…

A sexual dimorphism in the functional asymmetry of the damaged human brain is reflected in a test-specific laterality effect in male patients, explaining some contradictions concerning the effects of unilateral brain damage on intelligence in studies in which the influence of sex was overlooked.

In the high school testing program conducted by the USAF Recruiting Service there is occasional reference to relationships between the Airman Qualifying Examination and certain civilian tests. Information concerning these relationships can be useful to guidance counselors. This report contains data on the relationships between the Employee…

This kit presents all components of the Universal Nonverbal Intelligence Test (UNIT), a newly developed instrument designed to measure the general intelligence and cognitive abilities of children and adolescents (ages 5 through 17) who may be disadvantaged by traditional verbal and language-loaded measures such as children with speech, language,…

This study examined the construct validity of the Comprehensive Test of Nonverbal Intelligence (CTONI) in two separate investigations. The first study examined criterion-related evidence of validity across racial/ethnic groups on the CTONI and the Woodcock-Johnson Psychoeducational Tests of Achievement (3rd edition). The second study examined the…

An intervention study of 7-year-old, poor readers examined the extent to which factors of phoneme manipulation, rhyme, verbal ability, nonverbal ability, and phonological memory were predictive of responsiveness to teaching interventions. Only phoneme manipulation was a predictor for reading accuracy. However, for reading comprehension, verbal…

A study analyzed the relationship between foreign language learning and four variables, including: nonverbal intelligence, conceptual level, mother tongue, and mathematics. The aim of the study was to investigate whether the same mental processes are involved in poor and good language learning, regardless of the learner's mother tongue. The study…

Two tests, one with six cursive shapes and the other with six colored angular shapes to be arranged artistically, were examined to determine whether the degree of non-verbal artistic aspects of creativity is greater in products of individuals or in products of groups. Each test was give both individually and in small groups to 499 students (grades…

Thirty bilingual Hispanoamerican students between the ages of eight and thirteen were given verbal and non-verbal intelligence tests which were then correlated with overall school grade point average. Non-verbal tests resulted in higher correlations; the Raven Colored Progressive Matrices appeared to be the best predictor of school successes of…

IN THE LONGITUDINAL BERKELEY GROWTH STUDY, SUBJECTS WERE TESTED AT 16, 18, 21, AND 26 YEARS ON THE WECHSLER-BELLEVUE, AND AT 36 YEARS ON THE WECHSLER ADULT INTELLIGENCE SCALE, WHICH CONTAIN BOTH VERBAL AND NON-VERBAL SUBSCALES. THE MOST CONSISTENT INCREASES IN MEAN SCORES OVER THE PERIOD WERE IN INFORMATION, VOCABULARY, AND COMPREHENSION. DIGIT…
