title: Extraversion and the EEG: I. An evaluation of Gale's hypothesis.
abstract: The hypothesis of A. Gale that extraverts differ from introverts in EEG defined arousal only under moderately arousing conditions is examined. It is argued that the hypothesis is not entirely internally consistent and lacks empirical support. A re-analysis of the literature on which it was based points to problems in the measurement of extraversion as a more significant source of confounding than variation in conditions of testing.
