The two featured articles and eight commentaries on the WISC-IV (Wechsler, 2003) and WAIS-IV (Wechsler, 2008) in this special issue of "Journal of Psychoeducational Assessment" are of exceptional quality. As a collective, this special issue greatly advances the field of cognitive assessment by intelligently synthesizing the best of…

Current cognitive screening tests are difficult to use due to their deficit in cultural and conceptual significance and translation into other languages. The purpose of this study was to translate the Loewenstein Occupational Therapy Cognitive Assessment for Geriatrics (LOTCA-G) into Malay language and test its reliability and validity for…

Researchers interested in working memory have debated whether it should be considered a single latent cognitive ability or a set of essentially independent latent abilities distinguished by domain-specific memory and/or processing resources. Simultaneously, researchers interested in cognitive aging have established that there are substantial…

Studied 1,1621 adults to determine whether psychometric tests would retain equivalent factor structures among samples widely differing in age. Results confirmed configural invariance for all subsets, but did not establish complete or incomplete metric invariance for any set. (RJC)

This study investigated whether measures of habituation and dishabituation in early infancy predicted later intelligence. Results were compared with those from other comparable studies. It was argued that the psychometric acceptability of infant cognitive measures needs to be demonstrated before they can be considered to be potential predictors.…

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)

Studied 622 adults and 211 undergraduates to determine the relationship of perceptual speed and speed of marking psychometric answer sheets to individual differences in performance on psychometric tests. Findings suggest strong relationships between age, speed, and intelligence-test performance. (RJC)

The psychometric utility of six experimental cognitive style (CS) measures was analyzed. Examinees were 1,135 clients of the Johnson O'Connor Research Foundation who, during 1985, completed at least one of the six CS tests. Information is provided on measure reliability; relationships among CS measures; relationships with standard battery aptitude…

Studied the relationship between mental age and progression toward Piaget's stages of concrete operations and formal operations in a sample of middle class children. Formal operations in preadolescence and adulthood are discussed in relation to IQ. (GO)

The aim of this study was to investigate the strategies leading to test item responses in 60 young (20-25 years) and 60 middle-aged (35-40 years) adults, whose highest level of education had been either secondary, technical or university. Subjects were individually administered a 12 item test similar to Raven's Progressive Matrices, and were…
