Interaction effects of extraversion and neuroticism on detection thresholds.
Detection thresholds for electrocutaneous stimulation were measured in young male subjects by two different methods - a method of limits and a forced-choice method - the latter assumed to be less influenced by decision processes. Relations between the threshold measures and scores in the EPI extraversion (E) and neuroticism (N) scales were studied. High N-low E ("unstable introvert") subjects had the lowest thresholds. The result is in line with the predictions made on the basis of Eysenck's personality theory.
