Presented is a rationale for producing intelligent behavior through operant conditioning rather than predicting it by means of standardized intelligence tests which are said to require circumstances explicitly precluding intervention. (GW)

After administration of the Wechsler Adult Intelligence Scale (WAIS) and the Wechsler Intelligence Scale for Children (WISC) to 120 adolescents, it was found that higher scores were produced on the WAIS in the group with less than average intelligence, and by the WISC in the other groups.

Created an adaptation of the Digit Symbol subtest of the Wechsler Adult Intelligence Scale, the Digit Symbol Rotation test, and evaluated its "g" loading with 54 adults. Results suggest the Digit Symbol Rotation test has more factorial validity than Digit Symbol, but remains equally easy to administer and score. (SLD)

Administered a battery of 17 working memory tasks and a test for the Berlin Intelligence Structure Model (1982) to 128 young adults in Germany. General working memory capacity was highly related to general intelligence, and findings also suggest that specific working memory resources, as opposed to a general capacity, are the limiting factors for…

Data for the Raven's Advanced Progressive Matrices test from 3 large studies for a total of 818 adults show that although older adults perform like low-ability young adults when the measure of interest is the number correct, there does not seem to be an age-related difference in the type of reasoning used. (SLD)

Criticizes "The Bell Curve" for its lack of understanding of the philosophical nature of intelligence (and mind). Points out that various philosophical attempts to analyze the concept of intelligence are routinely ignored by empirical workers in the field of IQ testing because such philosophical work makes obvious the lack of connection…

Articles responds to some issues raised in "The Bell Curve: Intelligence and Class Structure in American Life," such as the nature of intelligence, its measurement, the importance of personal decisions in determining life outcomes, and the modifiability of intelligence in infants and young children. (Author/JDM)

Examines the factor structure of the Wechsler Adult Intelligence Scale-Revised across nine age groups using several methods of factor analysis, including reliable component analysis (RCA). Factor structure is discussed, and the usefulness of the RCA method is demonstrated. (SLD)

Studied the role of response fluency on results of the Raven's Advanced Progressive Matrices (APM) Test by comparing scores on a test of generation speed (speed of generating rules that govern the items) with APM test performance for 127 Belgian undergraduates. Discusses the importance of generation speed in intelligence. (SLD)

It has been suggested that computer simulations may be used for intelligence assessment. This study investigates what relationships exist between intelligence and computer-simulated tasks that mimic real-world problem-solving behavior, and discusses design requirements that simulations have to meet in order to be suitable for intelligence…

The Test of Nonverbal Intelligence-3rd Edition (TONI-3) and the Analogic Reasoning (AR) subscale of the Universal Nonverbal Intelligence Test (UNIT) were administered to 35 individuals with autism to determine whether real-world-knowledge deficits affected intelligence scores. The 2 tests are similar in format; however, the TONI-3 includes only…

Examination of measurement invariance tests the assumption that the model underlying a set of test scores is directly comparable across groups. The observation of measurement invariance provides fundamental evidence for the inference that scores on a test afford equivalent measurement of the same psychological traits among diverse groups. Groups…

The Federal School was a correspondence art school in Minneapolis, Minnesota in the early 20th century. At that time, scientific methods changed the organization and practice of commercial art training and industrial education, which included correspondence courses from the Federal School. Standards of intelligence were determined with…

Although a verbal intelligence test is directly a measure of what people know, it is indirectly a way of identifying people who can code and manipulate verbal stimuli rapidly in situations in which knowledge per se is not a major factor. (Author/BJG)
