This study examined differences in predicting achievement by sex on the Iowa Tests of Basic Skills (ITBS) from the verbal, quantitative, and nonverbal scores on the Cognitive Abilities Test (CogAT). The sample (n=10,000) consisted of all students in Grades 2, 5, and 8 who completed both tests in fall 1984. Examinations of means and standard…

Differences in learning processes were studied in more versus less intellectually able undergraduate students. Thirty subjects were selected to represent a wide range of general and mathematical reasoning abilities, based on the following test scores: Necessary Arithmetic Operations and Vocabulary Test V2 from the Educational Testing Service ETS…

College students were presented with a series of four problems, each presented in four different formats: verbally, in abstract symbols, in negative abstract symbols, and in geometric figures. Problem-solving performance was evaluated in terms of the sequence of questions that a subject asks in order to solve a problem. They were also tested by…

For the past 100 years we have been acting as if education in school was of words, by words, and for words, but in fact verbal literacy was preceded by visual literacy when humans communicated with body language before they had speech. American educators have been concentrating efforts on the left hemisphere of the brain in which the verbal…

To test the hypothesis that the amount learned from a manipulative, nonverbal oriented unit on electricity would be better predicted by a learning potential assessment procedure than from an IQ based classification (educable mentally retarded status), an EMR group and a regular class non EMR group were both exposed to the unit; untaught EMRs…

This manual discusses the characteristics of students with nonverbal learning disorders (NLD) and provides strategies to help students with NLD in the home and classroom environment. It begins by describing the symptoms of NLD, including lack of coordination, faulty spatial perceptions, lack of ability to comprehend nonverbal communication,…

Background: Five DNA markers (single-nucleotide polymorphisms, SNPs) have recently been found to be associated with general cognitive ability "g") in a sample of 7414 7-year-old twins. These children have also been studied at 2, 3, 4, and 7 years of age on measures of cognitive and language development and behaviour problems; family environment…

Nine conference papers discuss the psychology of deafness. They include seven papers from the United States: "Deafness: The Interdependent Variable" by M. Vernon and D. A. Rothstein, "The Reliability and Construct Validity of the Self-Concept of Academic Ability Scale-Form D for Hearing Impaired Students" by L. M. JOINER,…

This report contains a series of studies which represent ongoing research of six investigators, who seek to elucidate through empirical studies the psychological characteristics of culturally disadvantaged children. The chief aim has been to make comparative analyses of abilities and learning characteristics of children from intact subpopulation…

Gender differences in level and pattern of cognitive abilities were examined in 49 learning-disabled college students. Females were stronger in visual-motor abilities and verbal conceptualization, whereas the males' highest abilities were nonverbal visual-spatial. Both groups showed weaknesses in memory for digits and factual knowledge and in…

Because the achievement battery traditionally administered to Brazilian college bound students may discriminate against those who cannot afford to attend the best high schools or preparatory courses, tests were developed to measure aptitude for higher education, independent of ability or actual knowledge of course content. The focus of the…

In order to determine the differential ability of mildly retarded school children to profit from coaching on non-verbal, non-academic reasoning problems and to study their problem solving and conceptual behavior, the Raven Coloured Progressive Matrices Test was given to 72 educable students (IQ 55 to 80) in socioeconomically homogeneous suburban…

The present study examines a new battery of nonverbal cognitive measures used extensively with numerous preschool children. Seven nonverbal, individually administered measures of fluid reasoning and visualization were administered to these children. Raw scores were converted to age-corrected scaled scores and subjected to multivariate analysis of…

This report summarizes the findings of a 2-year longitudinal study of a number of aspects of the effects of television on three small Canadian communities, one of which began receiving broadcasts for the first time during the study. The three communities were roughly matched for population (650-870 people), population of areas served by the towns,…

A study investigated the validity and usefulness of the Affective Communication Test (ACT) which measures a person's ability to project a nonverbal message to others. The ACT test was reduced to 10 items and administered to 130 college students. The results were analyzed for interpersonal display of effect, public display, and small group display.…
