Using data from the Swedish Individual Statistics Project, changes in intelligence among 13-year olds are documented over a 25-year period. The average spatial and reasoning intelligence has risen successively. A clear increase is found for verbal intelligence in the 1960s, with more irregular growth since then. (SLD)

The relationship between psychometric intelligence and reaction times (RT) was studied in 60 undergraduates using an elementary cognitive task, the Sentence-Picture Verification Test. Results, which show that psychometric intelligence is substantially correlated with RTs even after practice, support the mental speed hypothesis of general…

This study to determine the validity of the Blind Learning Aptitude Test (BLAT), involving 30 students, found significant correlations between scores on the BLAT and braille oral reading speed, comprehension, age, grade, years of blindness, intelligence, and achievement. The correlation was greater between the BLAT and comprehension than between…

Describes an artificially intelligent multimedia computerized instruction system capable of developing a conceptual image of what a student is learning while the student is learning it. It focuses on principles of learning and adaptive behavioral control systems theory upon which the system is designed and demonstrates multiple user modes.…

Personality and intelligence associated with depressive symptoms in 99 young adults were evaluated using prospective data from preschool through adolescence. Found that depressive symptoms in males developed earlier than in females, and that adolescent females were more likely than adolescent males to express autocentric reactions, such as…

Notes that musical aptitude is not developed or nurtured through mere "exposure" to music but through active participation in singing and moving to music. Provides a rationale and suggestions for teaching singing in early childhood classrooms. (HTH)

Artificial neural networks (ANN), part of artificial intelligence, are discussed. Such networks are fed sample cases (training sets), learn how to recognize patterns in the sample data, and use this experience in handling new cases. Two cognitive roles for ANNs (intelligent filters and spreading, associative memories) are examined. Prototypes…

Presents a taxonomy describing various uses of artificial intelligence techniques in automated instructional development systems. Instructional systems development is discussed in relation to the design of computer-based instructional courseware; two systems being developed at the Air Force Armstrong Laboratory are reviewed; and further research…

The dichotomous Rasch model was applied to verbal subtest scores on the Intelligence Structure Test Battery for 905 12- to 15-year-old secondary school students in the Netherlands. Results suggest that, if any factor is used to increase difficulty of items, that factor should be used on all items. (SLD)

The effects of incidental learning were assessed in 2 experiments involving 201 seventh graders in Poland through an experimental paradigm based on the levels of processing theory. Data suggest that an important aspect of intelligence is "opportunistic" learning (learning in advance). Intelligent people take cognitive advantage of…

Describes five categories of software that can be useful in the basic writing classroom: computer-assisted instruction, computer-controlled instruction, artificial intelligence, computer-based rhetorical invention, and word processing. Evaluates each type of software in terms of their ability to fulfill the goals of basic writing instruction to…

Two studies assessed the construct validity of Greenspan's models of adaptive and social intelligence with 75 adolescents with mental retardation. Factor analysis measures of conceptual intelligence, adaptive behavior, and social intelligence yielded a practice-interpersonal competence construct. The second study, however, failed to establish the…

The Regression Discrepancy Model, intended to increase accuracy in assessing severe discrepancy between IQ and achievement scores in students with learning disabilities, is examined. The model's initial equation is shown to produce results which bias the detection of severe discrepancy at lower IQ levels. Methods to minimize or remove this bias…

The issues of construct validity, predictive validity, and item content bias on the Wechsler Intelligence Scale for Children-Revised (WISC-R) are examined. The review concludes that most objective data have not supported the issue of bias of the WISC-R when used with children of different ethnic backgrounds. (JDD)

Asa Hilliard, an African-American educator, stresses the following points: (1) the African-American cultural style tends to be more improvised, wholistic, and person-oriented than the European style; (2) teachers can be more democratic and equitable by recognizing cultural differences; (3) intelligence tests tend to hurt African Americans; and (4)…
