Twenty individuals (ages 8-18) with mental retardation and 20 controls matched for nonverbal mental age were assessed on receptive language level and nonverbal cognitive functioning. Results indicate that the nondisabled group placed less emphasis on the formal, sequential properties of language and more on semantic, conceptual properties.…

Study reported in a paper read at the Eastern Psychological Association meeting (Boston, April 1967).

Administration of nonverbal IQ tests to 12 children with normal language and 12 with language impairments (ages 8-10) revealed that the children with language impairments had lower scores than controls, and that nonlinguistic deficits of children with language impairments adversely affected their responses to specific types of items on nonverbal…

This review of the relevant literature in the area of numerical facility attempts to clarify the construct of numerical facility and provide guidance for items tapping this ability. The review is presented in five parts. The first section introduces two approaches that can be used to investigate numerical facility, including factor analysis.…

A new measure of the learning environment of the home was developed in order to examine the relationship between the environment of children and mental ability test performance. Results provide support for the use of the sub-environment approach in the study of intellectual performance. (Author/AG)

Administered six cognitive tasks to 115 men aged 50-93. Obtained two factors. The nonverbal performance factor was significantly predicted by age while the verbal factor was significantly predicted by education. The results suggest that verbal and nonverbal abilities may be determined by different antecedents. (Author)

Administration of verbal and nonverbal measures to 20 normal language and 20 specifically language-impaired children (ages 4-5) indicated that a "qualitative-differences" model of specific language impairment better accounts for the co-occurrence of poor verbal and poor nonverbal cognitive skills in subjects than a "low-normal"…

Differences in 3-month-old infants' vocal responsiveness to vocal-visual stimulation by mothers and strangers has been shown to be related to performance on both the Stanford-Binet at 3 years of age and the Illinois Test of Psycholinguistics at 5 years of age. The present retesting of 12 of the original 14 normal, first-born male subjects, now 12…

Reports the findings of two experiments conducted with South African senior high school students to examine the relationships of metacognitive strategies and nonverbal reasoning ability to test performance in mathematics and English comprehension. Suggests that teaching metacognitive strategies to students who lack such skills may improve their…

The suggestion of an underlying dimension in mental imagery despite low correlations among objective spatial and self report measures was investigated using data from two independent samples of 131 college students. The first study revealed some factorial independence in imagery aptitude, while the second study investigated individual patterns of…

Examined the relationships among two psychometric measures of nonverbal cognitive ability - The Wechsler Intelligence Scale for Children-Revised (WISC-R) and the Woodcock-Johnson Psychoeducational Battery-Tests of Cognitive Ability (WJPB-TCA) and a neuropsychological test of abstract reasoning and concept formation (Halstead Category Test) in 25…

Draw-A-Person (DAP) techniques are often used as developmental screening measures of non-verbal cognitive ability, particularly for young children who are being screened for possible early intervention services. The validity of the interchangeable use of three DAP scoring systems for kindergarten students was investigated by comparing scores and…

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 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.
