Summary: | 碩士 === 國立臺灣師範大學 === 教育心理與輔導學系 === 106 === Digit ratio, defined as the relative length of the 2nd and 4th digits, is a biomarker of prenatal androgen exposure. The more prenatal androgen you were exposed, the smaller the digit ratio. Research also suggested that androgen may influence the brain and body development of the fetus, and thereby affect individual’s cognition and behavior. Although correlational studies have found the relationships between digit ratio and behavioral traits, such as aggression and personality, there was no research exploring the relationship between digit ratio and the higher-level cognitive abilities. Specifically, this research aimed to focus on humor styles, gelotophobia, gelotophilia, katagelasticism and creativity. 150 participants (74 males and 76 female) were recruited and asked to fill out the questionnaires, including Mini-Markers, Humor Styles Questionnaire-TC, PhoPhiKat-TC and the New Verbal Tests of Creativity Thinking. The length of participants’ fingers was scanned and calculated as the digit ratio. The results showed that males had a smaller digit ratio than females on both hands, but the difference in the digit ratio between the hands (DR-L) did not differ between genders. As we controlled for sex, we found a negative partial correlation between the emotional stability and left-hand digit ratio, and a negative partial correlation between extroversion and DR-L. In addition, there was a negative partial correlation between DR-L and self-defeating humor. Furthermore, for the male group, katagelasticism was positively related to left-hand digit ratio, but was negatively related to DR-L, suggesting a contradicting result. As we controlled for sex, there were negative partial correlations between digit ratio, fluency, and flexibility. In general, this research examined the higher-level cognitive abilities from a biological point of view, providing insights into the research on humor and creativity.
