This study examined differences between Wechsler Intelligence Scale for Children-Third Edition (WISC-III) and Wechsler Intelligence Scale for Children-Revised (WISC-R) scores for 40 elementary students with learning disabilities. WISC-III Full Scale, Verbal, and Performance scores were lower than comparable WISC-R scores by one-third to one-half a…

One of the major problems in artificial intelligence (AI) text generation is text organization; a poorly organized text can be unreadable or even misleading. A comparison of two AI approaches to text organization--McKeown's TEXT system and Rhetorical Structure Theory (RST)--shows that, although they share many assumptions about the nature of text,…

Among a group of 103 children with a mean age of eight years, full-scale IQ correlation was significantly higher for monozygotic than dizygotic pairs. Monozygotic pairs also showed significantly greater concordance for subtest profile than dizygotic pairs. The usefulness of profile analysis is examined, and directions for future research are…

Comparisons of Wechsler Intelligence Scale for Children-Revised scores, for 24 children with learning disabilities demonstrating a low verbal, high performance intelligence quotient (IQ) discrepancy and 33 slow learning children having uniformly low verbal and performance IQs, revealed few cognitive differences beyond the Performance Scale…

Little is known about the academic processing speed (i.e., rapid automatic naming and academic fluency) of children and adolescents with emotional and behavioral disorders (EBD) served in public school settings. A cross-sectional design was used to investigate the (a) percentage of K-12 students with EBD served in public school settings with…

Administered three Wechsler adult intelligence scales to 72 undergraduates and tested the quality of means, variances, and covariances, utilizing subtest scale scores and IQs. Results indicated that the three scales were not parallel. Generally, the subtest scaled scores exhibited less similarity across the three scales than the IQ estimates.…

The IQ performance of children who experienced the birth of a younger sibling was found to drop 10 points during the next two years for singleton children and 5.8 points for last-born children from families of comparable size. The study controlled for sex, family size, age at assessment, and IQ before the birth of the sibling. (Author/RH)

Two studies compared intelligence quotient, reading achievement test results, and spelling errors in 57 adult dyslexics, 56 adult nondyslexics, and 25 adult compensated dyslexics. Results suggest that compensated dyslexics appear very similar to nondyslexics in their reading and spelling skills; however, there is a difference in the automaticity…

This paper addresses the problem of heterogeneity of samples of learning disabled (LD) children by comparing five different systems for identifying homogeneous subgroups in terms of their ability to predict longitudinal reading and mathematics scores. One hundred and sixty LD children served as subjects. Three of the five subgrouping systems were…

This document presents a study of natural language understanding of computer programs. In the study, the performance of IRUS, a natural language query system designed to interface with a database, was compared with the performance of preschool and early elementary school children in answering questions about a specific database. Questions used in…

The classification of intelligence has been a prime interest to many for over three-quarters of a century. The Wechsler scales of intelligence and the development of factor analysis have both played major roles in the shaping of psychometric thought. An examination of this joint history by means of a review of the factor analytic studies of the…

Compares the Genevan and Cattell-Horn theories of intelligence and describes both similarities and differences. Describes a study investigating the relation of the Piagetian operative level to the child's ability to use crystallized solution procedures (aids) in making elementary numerical comparisons. (HOD)

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.…

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…

Forty-eight preschool-age children were administered the Kaufman Assessment Battery for Children-Nonverbal Scale and the Wechsler Preschool and Primary Scale of Intelligence (WPPSI) Performance Scale. Pearson product-moment correlations between the two scales ranged from .59 for a language-delayed group to .79 for the entire sample. Subjects…
