PSYC18H3 Chapter : Emotions ch 2.docx
Document Summary
Darwin dethroned human being from their place as unique creations in the image of god. Darwin s evidence was the similarity of human emotional expressions to those of lower animals. His broader theory of evolution would change how scholars think about emotions. Selection pressures: these features of the physical and social environment that determined whether or not individuals survived and reproduced. Two kinds of sexual selection pressures determine who reproduces: y y. Intrasexual competition: occurs within a sex for access to mates. Traits that allows some to prevail over others are more likely to be passed on to succeeding generations. Intersexual competition: refers to the process by which one sex selects specific kinds of traits in the other sex. In the preference women report for males of higher status males seek out mates who are fertile. Our capacity to cooperate is a powerful determinant of who reproduces and who survives.
