{Reference Type}: Journal Article {Title}: Sexual Selection and Humor in Courtship : A Case for Warmth and Extroversion. {Author}: Hall JA; {Journal}: Evol Psychol {Volume}: 13 {Issue}: 3 {Year}: 2015 Sep 1 {Factor}: 1.738 {DOI}: 10.1177/1474704915598918 {Abstract}: This investigation examines a sexual selection-based argument regarding humor's role in courtship (i.e., humor production signals intelligence/creativity). Lens model (n =100) analyses suggest that humor production on Facebook profiles were self-reported and perceived to be associated with extroversion, not intelligence. Study 2 (n = 289) found that extroversion was associated humor production, but high school and college grade point average and American College Test (ACT) scores were not. In Study 3, pairs of opposite-sex strangers (n = 102) interacted for 10-12 min. Males' humor production and females' responsive laughter were both associated with females' dating interest. Both partners' dating interest was associated with simultaneous laughter. Without support for the sexual selection argument, three alternative explanations of humor's role in courtship are discussed.
