Results failed to replicate previous findings of a temporal processing deficit specific to the auditory modality in LI children. Further analyses resolved this apparent conflict between the present and earlier studies by demonstrating that age is an important variable underlying modality specificity of perceptual performance in LI children.…

Developmental changes in preschool children's awareness of the relative effectiveness of four nonverbal strategies in a memory-for-location task were investigated. Fifty-two preschool children (12 three-year-olds, 20 four-year-olds, and 20 five-year-olds) made paired comparison judgments as to the mnemonic effectiveness of marking, touching,…

Cognitive ability and behavioral adaptability are distinct, yet related, constructs that can impact childhood development. Both are often reduced in deaf children of hearing parents who do not provide sufficient language and communication access. Additionally, parental depression is commonly observed due to parent-child communication difficulties…

Three different analyses have shown that the more information available in a nonverbal decoding task, the less efficiently younger subjects utilize the information relative to older ones. This differential effectiveness in the utilization of available information was discussed in terms of processing capacity, effort, and strategies for sampling a…

Paper delivered in part at the annual meeting of the American Psychological Association in September, 1965.

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)

The assessment of hearing impaired children is fraught with a number of problems. These include lack of valid assessment measures, faulty theoretical assumptions, lack of knowledge regarding the functioning of cognitive processes of these children, and biases against these children. This article briefly considers these issues and describes a study…

This study of 8 language-disordered children, ages 5-8, found that subjects increased their nonverbal behavior as message conditions changed from unambiguous to ambiguous. Nonverbal indication was generally the only signal of ambiguity detection exhibited by subjects and language-matched peers, whereas age-matched peers consistently indicated…

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…

Psychological data were analyzed for 164 individuals (ages 3-15) with autism (IQs 14-143). Verbal IQ lagged behind nonverbal during the preschool years, but by school age the gap had closed. For school-age children with low IQs, math, spelling, and writing scores were consistent with IQ and reading was above IQ. (Contains references.) (Author/CR)

The number skills of groups of 7- to 9-year-old children with specific language impairment (SLI) attending mainstream or special schools were compared with an age and nonverbal reasoning matched group (age control [AC]) and with a younger group matched on oral language comprehension. The SLI groups performed below the AC group on every skill. They…

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…

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 reviews a theoretically inspired empirical investigation of individual differences in knowledge, abilities, and nonability traits as part of an ongoing effort to better understand adult intellectual development and to develop more accurate measures of adult intelligence. Twenty Knowledge Scales were constructed, drawing on…
