The purpose of this study was to investigate the relation between early mathematical skills and cognitive processing abilities for two samples of children in Italy (N = 40) and the Netherlands (N = 59) who completed both a cognitive test that measures Planning, Attention, Simultaneous, and Successive (PASS) processing and an early mathematical…

Examined the relationship between the Woodcock-Johnson Tests of Cognitive Ability (WJTCA) and Wechsler Intelligence Scale for Children-Revised (WISC-R) in a referral sample of 52 elementary students. Results showed comparable WJTCA/WISC-R global ability estimates, contrary to lower WJTCA scores found in recent studies with learning disabled…

Sources of continuity among nine measures of infant cognitive processing and later childhood intelligence quotient were examined through developmental structural equation models applied to a sample of 208 twin pairs measured from 7 to 36 months. Skills assessed appear related to general cognitive ability in a relatively unstable manner. (SLD)

Reliability and validity of a new measure of cognitive speed, the Speed of Thinking Test (SST), were investigated with 129 college students, who also completed a vocabulary test, a test of reading speed, and a test of reading comprehension. The SST appears to be a reliable and valid measure. (SLD)

Notes that the microgenetic method has revealed new information about normally achieving children's cognition, and reviews data from three different microgenetic studies. Concludes that there are similar sequences of strategy change, similar rates of strategy change, and similar frequency of strategy discovery and use in children with and without…

A matrix test was devised to assess cognitive skills associated with inferential reasoning. The format of the test requires the subject to choose, from among four alternatives, a figure which is related to other given figures on the basis of appearance, content, or spatial position in the matrix. The test consists of three perceptual matching…

Relationships between reading comprehension (RC) and critical thinking skills, vocabulary, and cognitive ability were examined using 3 tests with 165 underachieving first-year college students in a remedial reading class. The Iowa Silent Reading Test's vocabulary subtest best predicted RC. The Developing Cognitive Abilities Test's three subtests…

Two studies (N=4,261 persons) illustrate an inverse relationship between ability level and correlations among IQ measures. Low IQ subjects showed higher correlations than did high IQ subjects. Intercorrelations of IQ subtests, intercorrelations of cognitive ability measures, and correlations of IQ with measures of cognitive ability displayed the…

Arima's Discrimination Learning Test (DLT) was reconfigured, made into a self-paced mode, and administered to potential recruits in order to determine if: (1) a previous study indicating a lack of difference in learning performance between white and nonwhites would hold up; and (2) the correlations between scores attained on the DLT and scores…
