Arguing that sufficient theory exists about the interplay between human information processing, computer systems, and the demands of various tasks to construct useful theories of human-computer interaction, this study presents a structural model of human-computer interaction and reports the results of various statistical analyses of this model.…

The relationship between children's cognitive developmental level, as assessed by Piagetian tasks, and their performance on measures of intellectual and neuropsychological functioning was studied. Eight female and 22 male children--ages 8 to 12 years (mean=10.3)--with negative electroencephalographs and neurologic screening and no history of brain…

Stability of performance on the Kaufman Assessment Battery for Children (K-ABC) and the Stanford-Binet Intelligence Scale: Fourth Edition (S-B:4) over a 1-year interval was examined with a sample of 28 nonhandicapped preschoolers. Each child was administered both tests in counterbalanced order and retested in 1 year with either the K-ABC or the…

There are two main areas of activity hidden behind the catch-phrase "high technology": the domain of computers and communication, and biological engineering. Because both deal with patterns of organization and information, it would seem that linguistics could contribute to their advancement. The main concept in information systems is…

The report addresses the question of the structure of cognitive abilities, i.e., how many different abilities should be identified and the relations between abilities. Models suggested by Spearman, Thurstone, Guilford, Vernon, Cattell-Horn and others are reviewed. By combining features of the Vernon and Cattell-Horn models it is possible to…

The booklet describes the Association for Retarded Citizens' (ARC's) goal of coordinating efforts to seek a cure for mental retardation. Cures are defined as any intervention that would significantly increase intellectual functioning and adaptive behavior beyond the upper level of retardation. It is explained that because of the variety of causes…

The relationship between American College Testing Program (ACT) and California Test of Mental Maturity (CTMM) scores were explored. Four hundred and thirty-four undergraduate subjects of both sexes were selected from a midwestern university. Pearson product moment correlation (r) and Kendall rank correlation coefficient (tau) were used to measure…

This paper discusses a model of information storage and retrieval, the k-d tree (Bentley, 1975), a binary, hierarchical tree with multiple associate terms, which has been explored in computer research, and it is suggested that this model could be useful for describing human cognition. Included are two models of human long-term memory--networks and…

This presentation addresses three basic social issues generated by the computer revolution. The first section, "Money Matters," focuses on the economic effects of computer technology. These include the replacement of workers by fully automated machines, the threat to professionals posed by expanded access to specialized information, and the…

Given the uncertainty of the future and the rapidity with which computer technology is changing, a generalist position on the objectives of educational computing is desirable. This position insists that learning how to think and solve problems is the foundation of education and suggests that basic learning needs to be an integral part of the…

This is a collection of papers related to psychological assessment and counseling in Puerto Rico. Included are: (1) an introduction (in Spanish), by Joseph O. Prewitt-Diaz; (2) "A Procedure for Constructing Valid Cross-Cultural Attitude Measures for Use in Puerto Rico," by Cecil R. Trueblood; (3) "Perfil de Personalidad en el…

Discusses two types of test bias: the sex bias found in interest inventories and certain standardized achievement tests; and cultural bias found in some standardized intelligence tests. (HMV)
