Studies of recall and recognition short-term memory (STM) were reviewed, and a series of studies of serial recognition memory of normal and retarded children was described. In experiments using a recall procedure there were decrements in initial performance level with decreasing age and IQ but less evidence that forgetting occurred at a faster…

Examined were the effects of chronological age and mental age on the understanding of logical rules by four subject groups (10- to 14-years-old): 10 average IQ Ss, 10 learning disabled Ss, 10 older educable retarded Ss and 10 younger educable retarded Ss. (Author/CL)

The cognitive determinants of number series completion performance were studied by presenting a systematic set of problems to adults and to children of high and average intelligence, grades 4 and 5. Pearson correlations between these problems and the number series on the Cognitive Abilities Test were .51, .78 and .43 for the average intelligence,…

Twenty high mental age (MA) subjects and 33 low MA subjects who had been in a free word association test 30 months previously were retested with the Moran 80-Word List. At the time of the previous testing, subjects in the high group had a mean chronological age (CA) of 17.1 and mean MA of 11.5; subjects in the low group had a mean CA of 15.3 and…

Fifty-six children (ages 43 to 83 months) participated in an event conducted by two undergraduates dressed as clowns. Ten days later, interviews found metamemory ability, intellectual functioning, and temperament were helpful in determining a child's capacity to accurately recall information, although for the most part age was the best predictor.…

The concurrent and discriminant validity of La Prueba de Analisis Auditivo, a Spanish auditory perception test, and the validity of the perceptual deficit hypothesis and of hypotheses derived from verbal processing theory were evaluated in a sample of 114 second-grade Hispanic pupils receiving reading instruction in Spanish.

Students of high intellectual ability and their parents were tested on a battery of cognitive tests. Vernon's model of intelligence best fit results. A verbal-educational and a practical-spatial-mechanical factor explained most performance variance. Among children, age related to verbal but not spatial or mechanical abilities. (Author/RD)

Longitudinal data on the auditory forward and backward digit span (FDS and BDS) subtests of the Wechsler Intelligence Scale for Children (WISC) were obtained at five age levels (between 6 and 13), in samples of white and black children. Factor analysis and analysis of variance of the data were conducted to test 5 hypotheses, related to Jensen's…

The major emphasis of this study is on the comparative validities of paired-associate learning tests and IQ tests in predicting reading achievement. The study engages in a brief review of earlier research in order to examine the validity of two assumptions--that the construction and/or the use of a tactic that simplifies a learning task is one of…

To investigate the interrelationships between creativity and seven variables, 74 students in grades 4 through 8 plus the vocational group at a school for the deaf were tested. In addition to creativity, subjects were tested for intelligence, academic achievement, imaginative productions, perception by teachers, self-evaluation career aspirations,…

Problem solving flexibility (PSF), an ability commonly assessed in creativity batteries, was studied in a sample of middle class children (grades 1 through 3, average IQ 114), tested on questions resembling Guilford's consequences procedure. An hypothesis linking PSF with alertness to and interest in the environment was generally supported, more…

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…

The cognitive determinants of number analogy performance were studied by systematically manipulating the processing demands imposed by the items. To explore sources of developmental differences in analogical reasoning, subjects were included from two age levels, grades 4 and 5 and college. To allow the investigation of individual differences in…

The effects of age and intelligence levels upon word associations were studied in 96 intellectually retarded, normal, and superior children with IQ's of 65 to 80, 91 to 110, and 117 to 158 respectively. A word association and a word usage task (reliability coefficients of .91 and .98) called for homogeneous responses to six form classes--count…

Adolescents, ages 11-12 and 13-14, were tested for maturity of judgment about stability-change situations and about time perspective. (CP)
