Abstract

Raven's matrices and inspection time (IT) were recorded from 56 subjects under five arousal levels. Raven's and IT correlated strongly ( r =-.7) as predicted by processing-speed theories of g . In line with Eysenck's [Eysenck, H. J. (1967). The biological basis of personality. Springfield, IL: Thomas] arousal theory of extraversion, there was a significant inverted U relationship between Raven's scores and arousal. No support was found for predictions that the IT-Raven's correlation was affected by personality. Likewise, the prediction of Gardner [Gardner, H. (1983). Frames of mind: The theory of multiple intelligences. New York: Basic Books] that ability measures correlate only because they share linguistic mediation was not supported. Instead, the data are compatible with a model in which processing speed and personality jointly influence performance on intelligence tests via predictable additive effects of processing speed and quadratic interaction effects of arousal and personality.
