Agency and communion are fundamental dimensions underlying psychological processes. Although agency and communion are coherent dimensions, their origins, nature, stability differ across theoretical framework. Common to these frameworks are gender differences in agency and communion. The present study hypothesized that because agency and communion relate to gender, they may also relate to digit ratio. The present study is important because digit ratio may offer clues on the origins and nature of agency and communion, and their gender differences. Agency and Communion factors were extracted from implicit linguistic measures obtained by LIWC analysis of selfnarratives. Exploratory structural equation modeling indicated communion related to digit ratio in men, and gender differences in communion. Although the results supported the distal, biological influences of communion argued by evolutionary accounts, the null finding agency was not related to digit ratio, while not directly interpretable, did not contradict socialization accounts of agency. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2014. / FAU Electronic Theses and Dissertations Collection
