Comparison between Eysenckʹs and Grayʹs models of personality in the prediction of motivational work criteria

Impulsivity based on Grayʹs [Gray, J. A. (1982), The neuropsychology of anxiety: an enquiry into the function of the septo-hippocampal system. New York: Oxford University Press; (1991). The neurophysiology of temperament. In J. Strelau & A. Angleitner. Explorations in temperament: international perspectives on theory and measurement. London: Plenum Press]. physiological model of personality was hypothesised to be more predictive of goal oriented criteria within the workplace than scales derived from Eysenckʹs [Eysenck, H.J. (1967). The biological basis of personality. Springfield, IL: Charles C. Thompson.] physiological model of personality. Results confirmed the hypothesis and also showed that Grayʹs scale of Impulsivity was generally a better predictor than attributional style and interest in money. Results were interpreted as providing support for Grayʹs Behavioural Activation System which moderates response to reward
