Thirteen young adult men were given a test for introversion-extroversion. They were then tested to determine the number of presentations of a noxious stimulus which was required for adaption to the stimulus to take place, as measured by the galvanic skin response. It was found that extroverts adapted with significantly fewer stimulus presentations than did introverts. The results were related to Eysenck's theory concerning the introversion-extroversion dimension and conditionability.
