This article reports the first behavioral genetic study of relationships between alexithymia and four styles of humor: affiliative, self-enhancing, self-defeating, and aggressive. A total of 509 MZ pairs and 264 DZ pairs of twins completed the Toronto Alexithymia Scale-20 (TAS-20) and the Humor Styles Questionnaire (HSQ). Consistent with our predictions, alexithymia correlated negatively with affiliative and self-enhancing humor and positively with self-defeating and aggressive humor. All but one of the 16 phenotypic correlations that we report are significant at the 0.01 level. Also consistent with our predictions, the phenotypic correlations between alexithymia and humor styles were primarily attributable to correlated genetic factors and to a lesser extent to correlated non-shared environmental factors. Correlated shared environmental factors had no significant effect. Implications and limitations of this study are discussed.
本文报告了关于述情障碍与四种幽默风格（亲和型、自我提升型、自我挫败型和攻击型）之间关系的首个行为遗传学研究。共有509对同卵双胞胎和264对异卵双胞胎完成了多伦多述情障碍量表-20（TAS-20）和幽默风格问卷（HSQ）。与我们的预测一致，述情障碍与亲和型和自我提升型幽默呈负相关，与自我挫败型和攻击型幽默呈正相关。我们报告的16个表型相关性中，除一个外，其余均在0.01水平上显著。同样与我们的预测一致，述情障碍与幽默风格之间的表型相关性主要归因于相关的遗传因素，在较小程度上归因于相关的非共享环境因素。相关的共享环境因素没有显著影响。本文讨论了该研究的意义和局限性。
