To investigate the factors determining why some children succeed at certain intellectual tasks while others of equal or near equal IQ, age, and motivation are unable to master the same task, 145 female and 144 male eighth grade students were administered "An Inventory of Piaget's Developmental Tasks" (IPDT). Labeled as concrete,…

Retrospective longitudinal data on 21 boys with the fragile X syndrome were analyzed. Results indicated that 13 of the boys showed a significant decline in intelligence quotient at retest, suggesting that while young boys with this syndrome may be only mildly retarded, adults are usually moderately to severely retarded. (Author/DB)

Studied the sleep state organization and EEG patterns at term date in 53 preterm infants as an index of the maturity and integrity of neurophysiological organization that may have implications for their later development. (HOD)

In commenting on Linda Siegel's argument (in EC221505) that Intelligence Quotient is not causally related to reading difficulties, this paper argues that Intelligence Quotient is relevant to the definition of reading disabilities but that present knowledge may not justify its use in the selection of children for special services. (JDD)

This investigation (with 30 normal students and 30 students with reading disabilities, ages 7-15) examined the relationship between intelligence and phonological coding when ability was defined according to the Planning, Attention, Simultaneous, Successive (PASS) cognitive processing model. Findings indicate that phonological problems may not be…

Using data from a broader longitudinal study, this investigation explores within-subject and cross-generational stability of intellectual competence and the relationship of such stability to aggressive behavior. Data were gathered three times (when subjects' modal age was 8, 19, and 30 years). Initially, subjects included the entire population…

A longitudinal investigation was conducted on the development of conservation skills in learning disabled (LD) children. During each of 3 years, six measures of conservation from the Concept Assessment Kit (space, number, substance, weight, continuous quantity, and discontinuous quantity) were administered to 31 newly identified LD students and 33…

The effects of compensatory education programs in the United States during the past 20 years are discussed. The author believes the programs have had the least impact on scholastic achievement and intelligence quotient (IQ). The theoretical view of human intelligence and prevailing views of psychologists and educators of the 1960's regarding the…

Examines the contiguity of siblings within family structure--a concept reflecting how much of the family environment siblings share with one another--in relation to within family IQ scores. Results fail to demonstrate family structure effects. (HOD)

In a study of 86 individuals with mental retardation, participants were asked to identify the appropriate facial expression or word that corresponded to the emotional response in a vignette. Results indicated that age correlated negatively with choosing the right word or picture. IQ was a significant predictor of performance. (CR)

The position that intelligence and achievement are essentially different measures of the same construct has often been referred to as a "jangle fallacy." Such a position challenges the present practice of placing children in learning disabilities programs based on a discrepancy between Intelligence Quotient (IQ) and achievement. This…

Replicates and extends to older adolescents previous findings of factorial independence between IQ and daydreaming in both gifted and average children and young adolescents. Also aims to relate to the development of moral reasoning ability research findings of a decline in guilt and fear-of-failure daydreams among children, adolescents, and…

This study examined the concurrent validity and diagnostic efficiency of the Kaufman Brief Intelligence Test (K-BIT) with 75 elementary and middle school students with learning disabilities, who had been referred for triennial multidisciplinary re-evaluations. High and significant correlations were found between the K-BIT and the Wechsler…

This response to a paper by Linda Siegel (EC221505) discusses research on the relationship between social skills and Intelligence Quotient or academic performance. The research indicates that it is erroneous to assume that Intelligence Quotient or academic achievement account for the social problems of children with learning disabilities. (JDD)

In this commentary on Linda Siegel's paper (EC221505), it is argued that a minimum level of general ability is needed for successful reading performance. Above this threshold other kinds of intelligence are required and more important is the contribution of verbal efficiency, which is predicated on the covariance of phonology, morphology, and…
