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…

This study compared subjects from right-handed families and nonright-handed families in their ability to solve a mental-rotation task when instructed to use one of two different spatial strategies. Results suggested familial nonright-handers may be stronger in transformation of mental images, but weaker in reorientation in relation to left-right…

Examined critical features of tactile and kinesthetic processes by administering 8 traditional psychometric instruments and 14 measures of tactile and kinesthetic perceptual processes to 116 female college students in Australia. Results show, as is consistent with earlier findings, that visual-spatial processes are difficult to separate from…

The hypothesis that racial differences in IQ stem from differences in components of executive systems including knowledge base, control processes, and metacognition was investigated. Group differences in metamemory, strategy use, and general knowledge, but not perceptual efficiency, were observed. Metamemory predicted crystallized but not fluid…

Field dependence and spatial ability are examined as different labels for a common underlying dimension. Sixty college students completed two tests of field dependence and two tests of spatial ability. Results of an analysis of covariance found no evidence to view the two traits as distinct from each other. (Author/LMO)

Relationships between intelligence test scores and measures derived from reaction time and perceptual speed procedures were investigated. Only three reaction time measures produced correlations greater than .25 with a general intelligence factor. Test-retest reliability of reaction time measures was low. The reaction time-intelligence relationship…

A correlation exists between verbal ability test scores and name identity minus physical identity reaction times in a letter matching task. The present results support Carroll's (1981) suggestion that the reaction time difference is related more to speed than power component of standardized tests and is not optimum for prediction.
