Gray's Model of Personality and Signal Detection Theory: Uncovering New Relationships of Impulsivity and Anxiety with Learning and Performance Criteria

Research in learning and performance using Gray's (1972, 2001) theory of personality has increased substantially in the last decade. Gray's key postulations, that impulsive individuals are most sensitive to reward while anxious people are most sensitive to punishment, have been investigated using a number of learning and performance paradigms. This paper introduces a prgram of research in progress using Signal Detection Theory to examine learning and performance relationships with Gray's model.
