When administered to 125 deaf youngsters, ages 5-12, the WISC performance test had good reliability and predictive validity, but administration to some young or physically handicapped children proved difficult. The Colored Progressive Matrices proved satisfactory with older subjects, but its suitability for younger deaf children was not confirmed.…

Relationships between the McCarthy General Cognitive Index and WISC-R Full Scale IQ with the Wide Range Achievement reading scores were explored with a sample of 20 educable mentally retarded and 20 learning disabled children, ages six to nine. (Author/SJL)

The Peabody correlated significantly with the McCarthy General Cognitive Index, Verbal Scale, Perceptual Scale, and Memory Scale. A significant difference between the means of the two tests was found, with the Peabody yielding lower scores. (Author)

A study was conducted to ascertain whether use of an interpreter and/or a regular examiner in administering the WISC would affect test results of a group of Mexican-American children. Spanish administration of some scales of the performance test are likely to elicit optimum performance. (Author)

Research results show that there are no clear grounds for assuming that students today cannot read as well as they did 25 years ago. (DS)

The sustained attention of 16 mildly retarded and 16 nonretarded adults was assessed during 2 60-minute vigilance tests differing in memory demand. Performance of retarded subjects declined more rapidly in later stages than did that of the nonretarded subjects. Implications for the study of memory load are discussed. (SLD)

Examined concurrent validity of several new and revised conceptual language measures. Administered Bracken Basic Concept Scale (BBCS), Boehm Test of Basic Concepts-Preschool Version (Boehm-PV) or Boehm-Revised, Peabody Picture Vocabulary Test-Revised (PPVT-R) to 99 preschool children attending kindergarten screening. BBCS correlated significantly…

Of 75 elementary and middle school gifted students, 44 percent of students' Stanford-Binet Intelligence Scale: Fourth Edition (SBIV) Composite scores and 28 percent of students' Wechsler Intelligence Scale for Children-Revised (WISC-R) Full Scale IQ scores were over 10 points different from their Test of Cognitive Skills (TCS) Cognitive Skills…

Examined equivalence of mode of administration of the Career Decision-Making System, comparing paper-and-pencil version and computer-based version. Findings from 61 undergraduate students indicated that the computer-based version was significantly more reliable than paper-and-pencil version and was generally equivalent in other respects.…

Thirty-five gifted elementary children were tested with the Wechsler Intelligence Scale for Children III (WISC-III) and results were compared to a previous administration of the WISC (Revised). Scores were significantly higher on all three WISC-R global scales and most subtest scaled scores. Correlation coefficients between the tests were…

The relationship between speed of information processing (SIP) and psychometric intelligence was investigated by giving 60 college students (22 males and 38 females) 2 choice reaction time (RT) tests (modified Hick paradigm) and Raven's Advanced Progressive Matrices. Results support an association between intelligence and SIP. (SLD)

Using 49 undergraduates, short-term memory (STM) spans, STM probe-recall tasks, and complex working memory (WM) spans were studied to assess the relationships among STM, WM, and verbal ability. Results indicate that STM and WM are separate cognitive constructs, and that both STM and WM are important to verbal abilities. (SLD)

The Satz-Mogel Abbreviation of the Wechsler Adult Intelligence Scale--Revised (WAIS-R) was compared with a 7-subtest short form of 130 healthy and 40 neurologically impaired older adults. Both short forms were found similar for normal or impaired adults in comparison with the full WAIS-R. (SLD)

Warfarin dosing for thromboprophylaxis in post-operative patients is time-consuming. Warfarin-dosing nomograms can be used in post-operative arthroplasty patients, but warfarin requirements are lower in frail older people. We modified an existing post-arthroplasty nomogram to a frail-friendly version and evaluated its performance in a frail…

The authors demonstrate that the timing and sequencing of target durations require low-level timing and executive control. Sixteen young (M-sub(age) = 19 years) and 16 older (M-sub(age) = 70 years) adults participated in 2 experiments. In Experiment 1, individual mean-variance functions for low-level timing (isochronous tapping) and the sequencing…
