Two experiments involving students from grades 1-2 and 5-6 found strong connections between development and forgetting rates when the influences of learning ability were eliminated. Findings eliminated a hypothesis based on age variability in overlearning. (RH)

Examined research into the memory deficit of retarded readers within a working memory framework. Results showed fairly consistent evidence that reading retardation can be associated with a deficit in long-term storage of phonological information, which may affect retarded readers' ability to utilize the articulatory loop.

Jensen's ideas about two levels of intellectual abilities are criticized as being oversimplified. More than two levels of intellectual abilities and relationships between variables reflecting more than racial and socioeconomic status (SES) differences are suggested, arguing that Jensen's statements about race and SES differences are not properly…

A critique by Carroll of a study by Jarman and Das (EJ 171 820) is refuted in terms of the methodology and theory of the Jarman and Das study. Additionally, two general issues concerned with individual differences in cognitive processes and strategic behavior are elaborated beyond Carroll's discussion. (Author/CP)

An explanation is sought for the striking apparent failure of the interactions of intelligence and memory factors with socioeconomic status predicted by Jensen's Level I/Level II theory, in a study by Stankov, Horn and Roy (EJ 239 630). It is suggested that Level I ability is a category of narrower abilities involving rote learning and primary…

The research literature on aging was reviewed to determine findings with direct implications for educational programs for older persons and findings with no direct application but that raise further research questions. The focus was on cognition and learning in later life, predominantly on work published during the past two decades in major…

Cognitive change in the elderly can be due to several etiological factors which are empirically difficult to separate and clinically problematic to differentiate. Normal aging is accompanied by behavioral slowing. The slowing down of psycho-motor processes results in a lowered intelligence quotient, but cannot be taken as unequivocal evidence for…

This 4-year longitudinal study of logical reasoning found complex interrelationships among different cognitive processes of children ages 6 to 15. Piaget's stage theory is discussed in the introduction, with a focus on the concrete operational stage in middle childhood. In the study, a representative array of logical concept tasks and short-term…
