This study, involving 90 children with mental retardation and epilepsy, classified and compared level of retardation, neurological findings, and electroencephalograms with the quality of seizure control. No correlation was found between quality of control and any of these parameters. (Author/JDD)

A table is provided for determining the frequency of occurrence of Verbal-Performance discrepancies on the Wechsler Intelligence Scale for Children-Revised (WISC-R) in profiles of high Intelligence Quotient children. Warnings are offered regarding the adverse effect of subtest substitution or omission when administering the WISC-R to highly…

Proposes a definition of intelligence as the mental abilities necessary for adaptation to, as well as shaping and selection, of any environmental context. Applies this definition to current theories and testing in the field of intelligence, as well as to understanding of the role of intelligence in lifelong learning and success. (MMU)

Argues against the presence of dysgenic trends for IQ on the basis of absence of change in the differences between various groups. Illustrates this with an example of the numbers of children born to Black and to White women at different educational levels. Discusses the effects, mechanisms, and implications of dysgenesis for IQ. (MMU)

A battery of "g" loaded mental ability tests was administered to 274 Bedouin children and adolescents, full and half siblings from 106 families. Results demonstrate internal validity for the tests in this cultural context and support the idea that shared family environment is a strong determinant of sibling similarity for children in the…

Investigates the general factor and uniqueness characteristics of the individual tests of the Woodcock-Johnson Test of Cognitive Ability-Revised (WJTCA-R). Only 2 of the 19 WJTCA-R tests examined had low general factor loadings, while 2 had low uniqueness. All other tests had medium or high uniqueness. Discusses implications for clinical…

Examines the performance characteristics of 83 school-identified learning-disabled children on the Differential Ability Scales. Sixty percent showed a significant standard score discrepancy between the General Conceptual Ability and at least one achievement test. Implications regarding the educational diagnostic and intervention processes…

Two projective measures of object representations, the Concept of the Object on the Rorschach and the Social Cognition and Object Relations Scales, were compared with each other and measures of intelligence and pathology with 15 children and 94 adult patients. Results support the construct validity of object representations. (SLD)

Presents study results of Verbal and Performance Weschler Intelligence Scale for Children-Revised subscales collected from Native (n=691) and non-Native (n=234) children in grades 2 and 4 at four sites. Native children had substantially lower IQ scores, especially pronounced for the verbal subscales. Discusses implications for understanding IQ…

This response to Detterman and Thompson (1997) analyzes their criticisms of special education and presents evidence of the effectiveness of current instructional techniques for children with disabilities in contrast with the cognitive approaches favored by Detterman and Thompson. Assumptions about the significance of intelligence testing and…

Considers how IQ tests may not be an effective means of identifying English-as-a-second language (ESL) students with learning disabilities due to inherent cultural biases of the tests. Concludes that the use of IQ tests with ESL or English-dialect students is inappropriate when the student's first or primary language is different from the language…

Age differences within the yo-yo trend in IQ, caused when aging norms that produce inflated scores are replaced with new norms, were examined using longitudinal WISC, WISC-R and WISC-III records of students tested for special education services from 10 school districts. Descriptive and individual growth modeling analyses revealed that while the…

Cleckley (1941) hypothesized that true or "primary" psychopathic individuals have "good" intelligence. This study examined the relation between psychopathy and intelligence in 122 detained children and adolescents. We used the Psychopathy Checklist?Youth Version (PCL?YV; Forth, Kosson, & Hare, 2003) to assess psychopathy and administered novel…

Recent developments in the definitional literature on mental retardation emphasize the need to ground the concept of adaptive behavior in an expanded model of intelligence, which includes practical and social intelligence. Development of a direct measure of practical intelligence might increase the likelihood that an assessment of this domain…

We evaluated the predictive accuracy of short forms of the Wechsler intelligence scales for individuals with high functioning autism. Several short forms were derived from participants who had received the full procedure. Stepwise multiple regression analyses were performed to determine the strength of association between the subtests included in…
