Investigates extent to which perceptual factors of speed and flexibility of closure represent more general processes also operating in cognitive and personality domains by including in a single factor analysis perceptual tests and new tests requiring cognitive abilities resembling closure abilities operating in the perceptual domain.

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…

A sample of college students was used to determine whether there was a correlation between Lowenfeld's visual-haptic continuum and Piaget's concrete-formal continuum.
