The relationship between learning ability and memory-monitoring performance was studied for 289 undergraduates in a 5-stage feeling of knowing (FOK) procedure with confidence of recognition (COR) judgments. Results show that fast and slow learners do not differ in magnitude of FOK and COR. (SLD)

Examined whether the Worst Performance rule (G. Larson and D. Alderton, 1990) could be applied to a strategic memory task in which 81 children in grades 2 through 4 were asked to remember different lists of categorizable words. Results show strong support for the rule, with worst performance predicting more unique variance in IQ than any other…

Studied the role of olfactory processes within the theory of fluid and crystallized intelligence by testing 107 Australian college students with a battery of psychometric and olfactory tests. Results indicate the likely existence of an olfactory memory ability that is structurally independent of established higher-order abilities and not related…

Retarded subjects were compared with mental- and chronological-age matched controls on serial short-term memory (STM) tasks. Retarded subjects were inferior to the control groups on both primacy and recency items, under two recall conditions. These data are discussed in relation to possible mechanisms underlying IQ-related individual differences…

Evaluated was the continuous recognition memory of 20 undergraduate students and 20 retarded adults. Available from: Ablex Publishing Corporation, 355 Chestnut Street, Norwood, New Jersey 07648. (CL)

Studied the relationship of recognition memory, as evidenced by novelty preference in infancy, and characteristics of the home environment, measured by parental socioeconomic status, to children's later intellectual competence. Results for 69 Norwegian children, all born prematurely, show that visual recognition memory makes a significant…

The relationship between reasoning ability, as indicated by performance on conventional reasoning tests, and working memory capacity was investigated in 4 studies involving 723, 412, 414, and 595 military recruits, respectively. The results demonstrate a consistently high correlation between general reasoning ability and general working-memory…

The ability to generalize is probably the primary aspect of intelligence. The computer's inability to generalize is the major stumbling block associated with machine intelligence. (Author/CP)

Examined the relationship between elementary cognitive tasks and the general factor of intelligence ("g") through tests administered to 568 elementary school students in a study of twins. Findings indicate a memory processing component in addition to a general information processing component contributing to "g" estimates. (SLD)

A study was conducted in which 226 participants performed 12 tests, 6 thought to reflect verbal, quantitative, and spatial working memory (WM), and 6 of crystallized (Gc), fluid (Gf), and spatial (Gv) cognitive abilities. Confirmatory factor analyses (CFAs) were computed to test the unitary nature of the WM system. Six primary latent factors were…

It is yet unknown whether individuals with and without savant abilities being affected by the same mental disorder display differences with regard to their intelligence profile. To examine this issue, we compared the test performance of 33 savant and 26 nonsavant autistic subjects using the Wechsler Intelligence Scales-Revised for children or…

The paper reports on an investigation of attention and working memory as sources of intelligence. The investigation was concentrated on the relatedness of attention and working memory as predictors of intelligence and on the structure underlying the prediction. In a sample of 120 participants, intelligence was assessed by the Advanced Progressive…

Empirical data suggest that there is at most a very small sex difference in general mental ability, but men clearly perform better on visuospatial tasks while women clearly perform better on tests of verbal usage and perceptual speed. In this study, we integrated these overall findings with predictions based on the Verbal-Perceptual-Rotation (VPR)…

Working memory (WM) has been associated with the acquisition of arithmetic skills, however, the components of WM that underlie this acquisition have not been explored. This study explored the contribution of two WM systems (the phonological loop and the central executive) to mathematical performance in young children. The results showed that a…

A reevaluation of a number of experiments suggests that normal and retarded persons differ on short-term memory tasks from the time of initial stimulus exposure. The hypothesis that memory differences are due to differential encoding as a result of more adequate rehearsal by the normal subjects is unacceptable. (Author/BW)
