Visual/Verbal-Analytic Reasoning Bias as a Function of Self-Reported Autistic-Like Traits: A Study of Typically Developing Individuals Solving Raven's Advanced Progressive Matrices
Peer reviewed Peer reviewed
Direct linkDirect link
Fugard, Andrew J. B.; Stewart, Mary E.; Stenning, Keith – Autism: The International Journal of Research and Practice, 2011
People with autism spectrum condition (ASC) perform well on Raven's matrices, a test which loads highly on the general factor in intelligence. However, the mechanisms supporting enhanced performance on the test are poorly understood. Evidence is accumulating that milder variants of the ASC phenotype are present in typically developing individuals,…

Sources of Age-Related Individual Differences in Block Design Tests.
Peer reviewed Peer reviewed
Salthouse, Timothy A. – Intelligence, 1987
Three experiments investigated the possibility that adult age differences on block design tasks originate because of reduced efficiency with increased age in the cognitive processes associated with block manipulation. Older adults were substantially slower and less efficient than younger adults in performing tasks with minimized design…

Factor Analysis of the WAIS and Twenty French-Kit Reference Tests.
Peer reviewed Peer reviewed
Ramsey, Philip H. – Applied Psychological Measurement, 1979
The Wechsler Adult Intelligence Scale (WAIS) and 20 tests from the French Kit were administered to over 100 undergraduates. Analyses revealed ten factors: verbal comprehension, visualization, memory span, syllogistic reasoning, general reasoning, induction, mechanical knowledge, number facility, spatial orientation, and associative memory.…

Kilian, Lawrence J. – 1978
In this study, cognitive processes hypothesized to be relevant to the digit symbol task of the Wechsler Adult Intelligence Scale (WAIS) were examined. Fifty-two undergraduate education students were divided into four groups to receive four different treatments. All the students took the digit symbol test, followed immediately by a test of their…

A Split in the Verbal Comprehension Factor in WAIS and WISC-R Profiles.
Peer reviewed Peer reviewed
McGee, Shanna; Brown, Coke – Journal of Clinical Psychology, 1984
Examined the pattern of verbal subscale scores on the Wechsler Adult Intelligence Scale and Wechsler Intelligence Scale for Children-Revised given to college students (N=129) and elementary students (N=383). Results showed a triangle pattern (Comprehension scores higher than both Vocabulary and Information) that begins to appear at the…

Speed of Information Processing and General Intelligence.
Peer reviewed Peer reviewed
Vernon, Philip A. – Intelligence, 1983
This study investigated the relationship between measures of speed of cognitive information processing and intelligence test scores. Cognitive processing measures were significantly related to IQ scores. Reaction time tests measure cognitive operations basic to intelligence, and individual differences in intelligence are partly due to variability…
