Recently, different methodological approaches have been discussed as an explanation for inconsistencies in studies investigating sex differences in different intelligences. The present study investigates sex differences in manifest sum scores, factor score estimates, and latent verbal, numerical, figural intelligence, as well as fluid and…

This fact sheet provides answers to frequently asked questions about psychological evaluations for infants, children and adults who are deaf-blind, we hope to clarify the evaluation process and the active roles that may be taken by everyone who is involved--family members, professionals, educators, and the student. Finally, by discussing quality…

The validity of a technique for estimating premorbid intellectual functioning based on Wechsler Adult Intelligence Scale-Revised (WAIS-R) subtest performance and demographic information used in best-performance fashion was investigated with the 1,880 individuals from the WAIS-R standardization sample. Results support use of the approach. (SLD)

Research procedures used to evaluate the intelligence of children with specific language impairment are reviewed. Almost half of the 167 studies did not include adequate descriptions of intelligence assessment. (Author/JDD)

In the current paper we describe the methodology and results of the Oswego study, in light of D.V. Cicchetti, A.S. Kaufman, and S.S. Sparrow's (this issue) criticisms regarding the validity of the human health/behavioral claims in the PCB literature. The Oswego project began as a replication of the Lake Michigan Maternal Infant Cohort study.…

Problems with experimental research on mental retardation include: (1) difficulties with defining mental retardation; (2) neglect in demonstrating causal relationships; and (3) reliance on methodology not necessarily appropriate for defining the criteria of retardation. The author advocates abandoning definitions based on intelligence tests and…

Introduces the inspection-time (IT) measure in psychology, and argues that its much-replicated correlation with intelligence quotient (IQ) and its potential for theoretical tractability has more potential for the understanding of individual differences in cognitive ability than other indices of human information processing. It summarizes studies…

D.V. Cicchetti, A.S. Kaufman, and S.S. Sparrow (this issue) use six criteria to evaluate the published findings from seven different studies of PCB exposure and neuropsychological function. They point out a number of weaknesses or flaws in each study and conclude that these weaknesses make the overall conclusion that PCB exposure negatively…

This paper discusses dynamic/interactive approaches to psychological assessment based on the concept of induced change as a research tactic. Studies are reviewed showing how interactive assessment has yielded new knowledge in psychopathology; neuropsychology; learning disabilities; intelligence testing (in normal, deaf, and immigrant children);…
