Similarities And Differences Between Heterosexual And Homosexual Couples Based On Marq Data, Kraig S. Shattuck
Similarities And Differences Between Heterosexual And Homosexual Couples Based On Marq Data, Kraig S. Shattuck
Wayne State University Theses
There has been a lack of comparative research on homosexual couples, comparing them to heterosexual couples, which is also grounded in solid theory. In order to remedy this, evolutionary theory is used to make predictions on similarities and differences between heterosexual and homosexual couples within three domains, relationship satisfaction, jealousy, and mate guarding. It was predicted that 1) homosexual couples would not differ from heterosexual couples in relationship satisfaction; 2) some gender differences relating to jealousy would be the same and some would be reversed in homosexual individuals; 3) mate guarding would be present, but lower, in homosexual individuals as …

Across the animal kingdom, the sex that experiences the most reproductive variance tends to evolve sexually dimorphic traits—both behavioral and morphological—which aid in reproduction. Human evolution has been marked by greater male intrasexual selection and as a result, men display a variety of secondary sexual characteristics, putatively serving to enhance biological fitness. Among these, fundamental frequency, closely related to perception of pitch, among men is half that of women. Likewise, monotonicity, that is, variance in pitch across an utterance, is higher in men (i.e., women show greater variance in pitch) while formant dispersion, which gives the voice its timbre, is …
