Relationship between Level I and Level II Abilities and Problem Solving.
Peer reviewed Peer reviewed
Schroth, Marvin L. – Perceptual and Motor Skills, 1982
This study investigated the relationship between Jensen's Level I-Level II mental abilities and how they correlate with problem solving in college students. The Level I-Level II correlation was not significant, but intelligence and problem solving were significantly correlated. Results are discussed in relation to prior findings. (Author/RD)

Factor Analysis of the Revised Wechsler Memory Scale Tests in a Neuropsychological Battery.
Peer reviewed Peer reviewed
Russell, Elbert W. – Perceptual and Motor Skills, 1982
The Revised Wechsler Memory Scale, Wechsler Adult Intelligence Scale subtests, and Halstead-Reitan battery were factor analyzed. Five types of memory were isolated: immediate verbal, recent verbal, recent figural, figural learning, and verbal learning storage.

Comparison of McCarthy General Cognitive Indexes and Stanford-Binet IQs for Educable Mentally Retarded Children.
Peer reviewed Peer reviewed
Naglieri, Jack A.; Harrison, Patti I. – Perceptual and Motor Skills, 1979
Although the two scores were found to correlate significantly, the mean Index (45.8) was significantly lower than the mean IQ (64.) for this sample--suggesting that one should be cautious when using the McCarthy Index for placement. (Author/DLS)

Application of Recategorized WISC-R Scores for Adjudicated Adolescents.
Peer reviewed Peer reviewed
Miller, Lamoine J.; And Others – Perceptual and Motor Skills, 1980
This study assessed the utility of Bannatyne's recategorization of the WISC-R with a group of 97 adjudicated adolescents who varied in intelligence. Findings affirmed the extension of Bannatyne's recategorization to samples other than genetic dyslexics and supported his major hypothesis of stronger spatial than sequential abilities. (Author/SJL)

Intellectual Deficiencies in Left-Handers: A Review of the Research.
Peer reviewed Peer reviewed
Sunseri, Anita B. – Perceptual and Motor Skills, 1982
To determine whether the idea is empirically supported that the majority of left-handers were intellectually inferior to right-handers, current research was examined. Inquiry indicated that the cognitive performance of left-handers was not significantly lower. (Author/CM)

Effects of Lead Poisoning on Cognitive Test Performance.
Peer reviewed Peer reviewed
Krall, Vita; And Others – Perceptual and Motor Skills, 1980
Forty-seven lead poisoned children, treated and without encephalopathy, were compared with sibling controls on perceptual-verbal pattern comparisons of subtests of the Wechsler Intelligence Scale for Children (WISC) to determine whether there was brain damage. Results indicated that lead poisoning, treated, and without encephalopathy, does not…

Error, Response Time and IQ: Sex Differences in Cognitive Style of Preschool Children.
Peer reviewed Peer reviewed
Lewis, Michael; And Others – Perceptual and Motor Skills, 1968
In a study on cognitive style, reflectivity-impulsivity in response to task uncertainty was investigaged. At 44 months of age, 23 boys and 25 girls were tested on a matching-figures test. Correlations were made between number of errors, response time, intelligence, and sex. Results indicated that there were significant sex differences in preschool…
