Four studies involving 45 subjects found that children (ages 9-14) with nonverbal learning disabilities syndrome exhibited specific patterns of impairment in mechanical arithmetic and in psychosocial functioning, whereas children with poor performance in reading and spelling exhibited patterns of academic deficits (including arithmetic), but not…

The Matrix Analogies Test measures nonverbal ability of handicapped and nonhandicapped children, ages 5-17, in a culture-fair fashion. It assesses pattern completion, reasoning by analogy, serial reasoning, and spatial visualization, with a short form available as a screening instrument. This paper describes the test's administration, format,…

Findings of a study that examined whether high school size significantly supplemented factors identified as contributing to educational achievement and ability are presented in this paper. In general, two divergent viewpoints concerning school size have been argued. One view holds that large schools are better than small schools because they offer…

A study investigated the effects of selected psychophysiological factors known to affect cognitive functioning on the reading achievement of older adults. The subjects, 34 noninstitutionalized adults ranging in age from 50 to 88 years, completed measures of (1) self-reported mental and physical health, (2) nonverbal intelligence, (3) reading…

This study sought to define the relationships between reading skill, reading requirements, and success in a sample of navy Class "A" schools. A further objective was to provide a methodological demonstration of the procedures required to allow an inference about causality in these relationships. Reading skill was compared with a nonverbal measure…

Language-impaired children (N=87) were assessed at the ages of 4, 4 1/2, and 5 1/2. In 37%, the language disorder resolved by 5 1/2 years (44% resolution in those with normal nonverbal ability). Outcome for individuals could be predicted with 90% accuracy at four years. (Author/KM)

The relationship of Mexican-Americans' degree of acculturation to analytic cognitive style and verbal and nonverbal intelligence was investigated. Findings revealed that when Mexican-Americans become similar to Anglos in acculturation, there is no significant difference in intelligence scores. (KH)

Some specific intellectual abilities show consistent sex differences which vary in degree according to types of tests and samples examined. Reviews the empirical support for these differences, as well as the methodological difficulties, data and sampling limitations, interpretative biases, and contradictory results of much of the sex-difference…

Adolescents with nonverbal learning disabilities are characterized by poor fine graphomotor skills, poor organization, and inaccurate perceptions of social situations. Effective remedial interventions include training students in study skills, writing skills, organizational skills, and social skills, and in ways to plan, risk, and act on their own…

This study followed 96 gifted students from kindergarten through high school and found that students who qualified for the gifted program on the basis of verbal or quantitative reasoning abilities performed better in academic subjects than did students who qualified only on the basis of nonverbal abilities. (Author/JDD)

The constancy of intelligence quotients (IQs) of 161 gifted Israeli children, obtained initially in grades K-4 and retested 1-4 years later, was examined. Results indicated that 86% still qualified as gifted on the retest, with mean differences of five to eight IQ points. Performance scores tended to remain constant, whereas verbal scores tended…

Evaluation of 17 children with autism at the ages of 6 to 15 and then again at ages 13 to 25, suggested that, for the majority of people with autism, there may be little development of a theory of mind. For a minority, development may extend to the equivalent of a 3- to 4-year-old level by the teenage years. (JDD)

Examines whether the characteristic reading speed impairment of German dyslexic children resulted from a general skill-automatization deficit or a phonological deficit. Tests a dyslexic and nondyslexic group of boys in grade 2. Concludes that difficulties in learning to read are due phonological deficit and not a general skill-automatization…

Review features of nonverbal learning disabilities in terms of personal, social, and academic manifestations, including deficits in reading comprehension, graphomotor coordination, mathematics, and science. Examines the neuropsychological and learning components associated with developmental right-hemisphere brain syndrome and outlines effective…

In a recent article in this journal, Naglieri and Ford (2003) claimed that Black and Hispanic students are as likely to earn high scores on the Naglieri Nonverbal Ability Test (NNAT; Naglieri, 1997a) as White students. However, the sample that Naglieri and Ford used was not representative of the U.S. school population as a whole and was quite…
