• Cortisol levels following DST were positively correlated with the depression as well as the social introversion MMPI scale scores, and negatively correlated with the hypomania scale scores [2].
• In males, weak but significant linear correlations (Pearson product-moment and Spearman rank correlations) were found between platelet MAO activity (p-tyramine and benzylamine as substrates) and the extraversion/introversion dimension [3].
• To test the hypothesis that personality characteristics are related to alcohol-effect expectancies, 256 (115 men) college students were divided into groups on the basis of self-reported alcohol consumption and anxiety and introversion scores on the Sixteen Personality Factor Questionnaire [4].

• The results suggest that the relationship between neurotic introversion and sensitivity to CCK requires closer scrutiny [7].
• The GH response (area under the curve) after apomorphine injection was positively correlated with the social introversion scale scores (r = 0.56, df = 19, p less than 0.01) and the anxiety scale scores (r = 0.45, df = 19, p = 0.04) [8].
