Research has indicated that school aged (6-16 years) versions of cognitive assessment instruments have varying levels of linguistic demand, which could impact assessment results for placement purposes. However, a significant limitation to this research is the fact that it has not been replicated with cognitive assessment instruments used in…

A QUALITATIVE AND CLINICAL ANALYSIS OF COGNITIVE FUNCTIONING WAS DETERMINED BY ADMINISTRATION OF THE STANDFORD-BINET INTELLIGENCE SCALE AND THE WECHSLER INTELLIGENCE SCALE FOR CHILDREN TO A SAMPLE OF 65 NORMAL CHILDREN. EXAMINATIONS AND OBSERVATIONS WERE MADE FOR EACH CHILD DURING HIS INFANCY, PRESCHOOL, LATENCY, AND PREPUBERTY PERIODS. ANALYSIS…

The OST is a technique quite different from anything reported elsewhere in the literature. The model underlying OST work assumes that an individual's intellect, at any given point in time, is the set of all information he has at his disposal at that point in time. The set of concepts an individual has at any point in time may radically change over…

This study describes the developmental function and cross-age pattern of individual differences in mental test behavior during the first 5 years of life. Accompanying the study are brief commentaries by Ina C. Uzgiris and Earl S. Schaefer and a reply by the authors. (JMB)

A brief review of these tests is provided, and it is concluded that the procedures possess a number of characteristics that make the evaluation of change in intelligence a tenuous proposition. (Author)

Reports a study of the correlation between intellectual development and students' understanding of scientific concepts and science processes. Results are reported concerning the reliability and validity of Piagetian or Piagetian-like tasks as measures of students' level of formal reasoning. (Author/SA)

The relative effects of chronological age, mental age, IQ or Piagetian task performance were investigated among 143 Ss of high, average, and low IQ. Two kinds of group comparisons were made on fifteen tasks: (1) groups of the same chronological age, but different mental age and IQ, and (2) groups of the same mental age, but different chronological…

Raven's Progressive Matrices test items were analyzed for M demand (Pascual-Leone's developmental construct). Data on second- and third-grade subjects were analyzed for extent of absolute agreement of Raven and Figural Intersection Test (FIT) scores. Raw scores on the Raven could be deduced on the basis of FIT performance. (Author/RD)

Delineates the current consensus regarding the nature and the development of intellectual ability. Examines when one would expect general abilities to moderate the relationship among domain-specific and other processes. Reviews recent studies in which general abilities were used as independent variables or covariates. Suggests that generally,…

Whether "psychometric" and "Piagetian" kinds of intelligence are similar is a question of whether they have similar courses of development with age. When using factor analysis to address this issue, age effects must be eliminated in order to assess relations among measured constructs. Reanalyses of previous results were…

The application of Piaget's theory of cognitive development to the assessment of mental ability of the mentally retarded is presented. Following a discussion of developmental theories and diagnosis of mental development, testing interviews demonstrate the limits of cognitive thought at each of three stages. Abnormal intellectual oscillations are…

Relationships among Piagetian reasoning assessments and standard measures of intelligence and achievement were determined in 1972 by Stephens, McLaughlin, Miller, and Glass (EJ 055 112). The data were reanalyzed by Humphreys and Parsons in 1979 (EJ 218 642). In reply, Glass and Stephens note fallacies in Humphreys' and Parsons' reasoning.…

Change in cognitive functioning is an important aspect of human aging and a key outcome in many medical conditions. However, cognitive change can rarely be measured directly, since prior cognitive data do not exist for most people. We examined the criterion validity and one-year stability of the difference between National Adult Reading Test…

Stephens et al. (EJ 055 112) committed a serious methodological error in holding chronological age constant in their IQ measures and allowing it to vary in their Piagetian developmental measures. This error is unrelated to differences in factor rotation methods used by these authors and was not answered in their reply. (CTM)

The Mayes Motor Free Compilation (MMFC) assesses mental ability in young (under age 2) children with motor disabilities. This study evaluated the concurrent validity of the MMFC by administering it and the Bayley Scales of Infant Development to normal children. Findings suggest that the MMFC provides a valid estimate of mental age, even without…
