All of us have been raised swimming in a sea of information regarding what sex, gender, and sexuality are and what it means to be of a certain sex, gender, and sexual orientation. But how much is fact and how much is fiction? Are people with penises always boys? Are women more nurturing? Is being gay genetic? This course aims to peel the curtains away and look at what the psychological science really says about sex, gender, and sexuality. This course will be challenging in that it will require students to examine their own experiences with their sex, gender, and sexuality as well as question their own assumptions about sex, gender, and sexuality. Having gained knowledge in an area often ripe with misperceptions, students will also be tasked with developing a proposal to increase knowledge regarding the psychology of sex, gender, and sexuality in a target audience of their choice.
