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…

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…

THE JOHNS HOPKINS PERCEPTUAL TEST (JHPT), REVIEWED IN THIS PAPER, WAS DESIGNED TO MEET THE NEED FOR A BRIEF, EASILY ADMINISTERED, NON-VERBAL INSTRUMENT TO ASSESS THE INTELLECTUAL FUNCTIONING OF CHILDREN. THE DATA ON THIS INSTRUMENT INDICATES THAT IT IS RELATIVELY CULTURE FAIR AND USEFUL FOR TESTING CHILDREN WHOSE PHYSICAL HANDICAPS PRECLUDE THE…

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…
