In this article, time effects on intelligence test scores have been investigated. In particular, we examined whether the "Flynn effect" is manifest in children from the middle and higher IQ distribution range, measured with a child intelligence test based on information processing principles--the Leiden Diagnostic Test. The test was administered…

A probe-type serial memory task was used to determine whether 3-dimensional objects would produce better recall than colored pictures of the same objects in elementary school students with low IQ's. (ST)

The major finding of this study is that there is a larger socioeconomic status or Negro-White difference on intelligence measures than on measures of rote learning and memory. The difference in the performance of Negro and White children increases with age. (EH)

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)

It was concluded that age and IQ have strong influences on acquisition-retrieval, but that forgetting rate is independent of these variables. (Author)

Two experiments were concerned with exploring the relative accessibility and availability of category information in retarded adolescents in comparison with CA equivalent nonretarded subjects. (Author/SB)

A protocol for screening the complex verbal, simple verbal, simple visual, and spatial working memory was tested on 125 persons with mild, moderate, and severe mental retardation. Results found the test discriminated well between levels of mental retardation, correlated reasonably well with IQ, and possessed relatively good test-retest…

Results of this study suggest that availability of a consistent set of color labels is related more closely to recognition accuracy than is the spontaneous production of labels in a color recognition task. (Authors)

Study replicates and extends the results obtained by Attig and Hasher (1980) in finding null effects for adult age variation and instructional variation on a relative frequency judgment task. Finds nonsignificant covariation for both young and elderly adults between judgment proficiency and paired-associate learning proficiency. (Author)

Subjects between the ages of 50 and 86 years were given portions of the Halstead-Reitan Neuropsychological Test Battery, the Wechsler Memory Scale, and the Wechsler Adult Intelligence Scale. Younger subjects performed significantly better than older subjects on 10 of the 18 neuropsychological measures used. (Author/BEF)

Visual preference technique was found to be a method for exploring the genesis of normal and abnormal selective attention, pattern discrimination, and recognition memory. The study of infants with differing degrees of risk for mental subnormality produced substantial evidence for relationship between early visual selectivities and future…

The Revised Wechsler Memory Scale, Wechsler Adult Intelligence Scale subtests, and Halstead-Reitan battery were factor analyzed. Five types of memory were isolated: immediate verbal, recent verbal, recent figural, figural learning, and verbal learning storage. Loadings of memory and nonmemory tests indicate a closer relationship between some of…

A study trained 10 5-year-old typical children, 11 5-year-old gifted children, and 11 7-year-old typical children on strategy use. Several differences among groups were found, generally favoring the gifted children in terms of performance and maintenance of strategies. In addition, the gifted children seemed to use categorization strategies…

A study examined memory for pictures and words in 16 adults with mental retardation and 24 controls. Pictorial superiority effects occurred in free recall and recognition for both intelligence-level groups. Correlational analyses indicated working memory span was primarily related to recall performance, irrespective of stimulus format. (Contains…
