A battery of 28 individually administered tests, comprised of measures derived from the work of Piaget, of simple and complex learning, of language, short-term memory, long-term memory and intelligence were given to 210 children aged 5 to 6 during their first year of schooling. (Editor)

Results from a representative sample of 123 adults in the United Kingdom tested with the Wechsler Adult Intelligence Scale-Revised and a test of word identification time are in line with previous findings that speed of information processing is significantly related to performance IQ but not to verbal IQ. (SLD)

A modal model of information processing was defined, and nine tasks that could be completed by persons with mental retardation were developed to operationalize the model. Results showed that individual differences in higher mental processes are highly dependent on basic cognitive abilities and can be predicted from them. (Author/JDD)

This article responds to commentaries (EC 604 996-998) on a paper by Douglas Detterman and others (EC 604 995), which developed and tested a modal model, with young adults with and without mental retardation as subjects, to assess basic cognitive abilities in relation to cognitive deficits. (JDD)

Students (n=210) in learning disabilities research centers were administered the Wechsler Intelligence Scale for Children-Revised and the Woodcock-Johnson Psychoeducational Battery-Revised. A model considering the reliability of each measure identified learning disabilities three times more often than a regression analysis model. The regression…

Tested infants at five and seven months of age for visual novelty preference. Tested the same infants at 12, 24, and 36 months by means of a battery of cognitive and language tests that compare novelty preference to general and specific cognitive abilities. Results support recent findings that infant novelty preference is predictive of later IQ.…

The validity of the fourth edition of the Stanford-Binet (S-B IV) test was studied with 30 linguistically precocious children at ages 20, 24, and 30 months. Validity at 24 months was questionable. Problems in using the test with very young children are discussed. (SLD)

There are several studies showing that working memory and intelligence are strongly related. However, working memory tasks require simultaneous processing and storage, so the causes of their relationship with intelligence are currently a matter of discussion. The present study examined the simultaneous relationships among short-term memory (STM),…

The influence of neurological and demographic variables on neuropsychological test performance was examined in 100 9- to 16-year-old children with traumatic brain injury (TBI). Regression analyses were conducted to determine the relative contributions of coma, neuroimaging findings, ethnicity, socioeconomic status, and gender to variance in…

College undergraduates learned word lists involving three-term contingencies (stimulus-response-outcome). Learning rate was correlated approximately 0.5 with scores on Raven's Advanced Progressive Matrices (Raven) but did not correlate significantly with several tasks (inspection time, card-sorting, trail-making, PASAT) shown to be associated with…

Individual differences in reading and cognitive processing among a sample of generally poor readers were studied in order to answer two major questions: Do they have a specific cognitive style that favors global-simultaneous strategies and a weak sequential strategy? If they do not have a distinct cognitive style or strategy, but are merely poor…

Characterizes intelligence in terms of learning processes and uses the concepts and methods of other disciplines to understand how the conditions responsible for the development of its constituent processes and the manner of their organization lead to variations in effectiveness of intellectual functioning. (Author/JM)

In this study, cognitive processes hypothesized to be relevant to the digit symbol task of the Wechsler Adult Intelligence Scale (WAIS) were examined. Fifty-two undergraduate education students were divided into four groups to receive four different treatments. All the students took the digit symbol test, followed immediately by a test of their…

In investigations of decline of intellectual status with age, cross-sectional and longitudinal studies give divergent results--the former show almost universal declines in test performances among older groups while the latter often show gains. Although few structure-of-intellect (SI) factors have been explored in relation to adult ages, two kinds…

This paper examines reports of empirical research on Feuerstein's "Instrumental Enrichment" (FIE) as a method of teaching thinking skills and asks what can be concluded from these reports with regard to: (1) the nature and statistical reliability observed FIE effects and (2) the "amount" of FIE for effects to appear.…
