Scores of 66 elementary students (referred for poor learning progress) on the Peabody Picture Vocabulary Test-Revised (PPVT-R) were below mean performance on all Stanford-Binet Intelligence Scale-Fourth Edition (SB:FE) area scores except memory. The study refutes the assertion that the PPVT-R is an appropriate screening instrument for the SB:FE.…

In four year olds who had been exposed to polychlorinated biphenyls (PCBs) before birth, prenatal exposure was associated with less efficient visual discrimination processing and more errors in short memory scanning. Postnatal exposure was unrelated to cognitive performance. (GLR)

Calculated reliability estimates for the Mexican-American (n=160) and non-Hispanic white (n=1,569) standardization sample at 11 age levels on the Kaufman Assessment Battery for Children using computed variance components. Results suggest that the test is equally reliable for both non-Hispanic white and Mexican-American children at all age levels.…

A discriminant analysis of characteristics of students with behavioral disorders in three progressively more intensive placements indicated that age at time of diagnosis was the strongest discriminating variable contributing to placement outcomes. Younger, brighter students tended to be mainstreamed, and older students with more externalizing…

Reviews four books: (1) "On Intelligence. . .More or Less: A Bioecological Treatise on Intellectual Development" (Stephen J. Ceci); (2) "Knowing Children: Experiments in Conversation and Cognition" (Michael Siegal); (3) "Adolescents and Their Families: Paths of Ego Development" (S. T. Hauser and others); and (4) "Adolescence: An Anthropological…

Present schooling culture reflected in narrowly conceived testing, grouping, and grading programs discourages the kind of sustained, collaborative inquiry that should characterize America's schools. Assessment programs must change to promote instruction systems that encourage student initiative and perseverance to pursue unanswered questions.…

Discusses three approaches to building intelligent systems: artificial intelligence, neural networks, and behavior analysis. BANKET, an object-oriented software system, is explained; a commercial application of BANKET is described; and a collaborative effort between the academic and business communities for the use of BANKET is discussed.…

Discussed is the search for life on other planets similar to Earth based on the Drake equation. Described are search strategies and microwave searches. The reasons why people are searching are also discussed. (KR)

Evaluated measures of infant cognitive development in 208 pairs of twins at 7, 8, and 9 months of age. Results contributed to the growing evidence of stability in intellectual development from infancy. (RH)

Elementary school children's evaluations of peer tutoring were compared with their evaluations of the traditional practice of solitary work on tests to determine their conceptions of fair practices in testing and learning situations. Findings support the conclusion that children's understanding of different types of situations is reflected in…

This study examined the scores obtained by 21 elementary-level gifted students on 4 different intellectual measures--Stanford-Binet (LM), Stanford-Binet (Fourth Edition), Otis-Lennon School Abilities Test, and the Cognitive Abilities Test. Results showed that the population of gifted students identified will vary greatly depending upon which test…

Interviews with 21 high-functioning adults with autism and 20 mildly to moderately mentally retarded adults without autism indicated that the mentally retarded group had more sexual experiences, with no intergroup differences in sexual knowledge or interest. Intelligence quotient was positively correlated with knowledge scores and males had…

This study found that a group of 20 children (ages 6-12) with autism and a group of 20 children with developmental receptive language disorder both manifested a relative sequential processing deficit. The groups did not differ significantly on overall sequential and simultaneous processing capabilities relative to their degree of language…

Assessment of 21 males (ages 4-27) with fragile X syndrome found that subject's age was associated with age-equivalent levels of both simultaneous processing and achievement, but not with levels of sequential processing. A smaller longitudinal study confirmed the presence of a plateau in sequential processing after the age of 10 years. (Author/JDD)

Describes the Portable AI Lab, a computing environment containing artificial intelligence (AI) tools, examples, and documentation for use with university AI courses. Two modules of the lab are highlighted: the automated theorem proving module and the natural language processing module, which includes augmented transition networks. (23 references)…
