Correlations between the Standard Progressive Matrices test (SPM) and the California Achievement Test, Reading, Language, and Mathematics Tests were examined for 99 Hispanic and 93 non-Hispanic Caucasian seventh-grade students. All correlations were highly significant. Supports continued use of the SPM as a measure of nonverbal intellectual…

The Rasch latent trait model was applied to investigate the relationship of performance on Raven items to expectations for individuals at different levels of the underlying scale. The use of Rasch model in instances of small samples and issues related to the interpretation of the model to Raven-type data are discussed. (DWH)

Inspection times for both auditory and visual stimuli were correlated with verbal and nonverbal intelligence. Correlations were -.3188 and -.0929 for auditory and visual inspection times with verbal intelligence, and -.2322 and -.2676 with nonverbal intelligence. Results do not support claims that inspection time is closely related to…

A study of the responses made to problems selected from Raven's Progressive Matrices showed differences in the kinds of errors typically made by eighteen-year-old students. Nine problems were used and the 68 subjects were told to draw their answers on the answer sheets. There were two trials per puzzle. A classification system, devised for errors,…

Analyzed performance of 183 Navajo students (aged 13-15) from Bureau of Indian Affairs and public schools in Arizona and New Mexico on the Raven Standard Progressive Matrices (RSPM). Reported RSPM as a "culture fair" measure of non-verbal mental processing with secondary level Navajo students. (NEC)

The roles of attention in reaction time and in relationships among reaction time, intelligence, and achievement were studied in seventh graders. Reaction time measures were correlated with attention and perceptual speed as well as general intelligence and achievement measures. Implications for current theories linking reaction time and…

Where estimation of abilities in the lower half of the ability distribution for the Raven Progressive Matrices is important, or an increase in accuracy of ability estimation is needed, the multiple category latent trait estimation provides a rational procedure for realizing gains in accuracy from the use of information in wrong responses.…

Information processing was measured in terms of reaction time and movement time to stimulus displays which differed in amount of information transmitted. Only reaction time increased as a linear function of number of bits in the stimulus display. Both show individual differences which significantly correlated with intelligence. (Author/RD)

Reaction time and movement time were negatively and moderately-to-strongly correlated with Ravens matrices performance and with reading comprehension and performance on the California Test of Basic Skills for 20 ninth-grade girls. Weaker relationships were found for mathematics and English grades, although the direction was consistently negative.…
