Individual Differences in Mating Psychology Well-researched dimension along which people vary is “Sociosexual Orientation” (SOI) Measures both attitudes towards sex and sexual behaviors Results in score that is continuously distributed; lower bound close to zero, upper bound unconstrained Low SOI people (“restricted sociosexual orientation): Demand commitment and closeness in a relationship before engaging in sex High SOI people (“unrestricted sociosexual orientation”): Comfortable engaging in sex with less commitment or closeness

Validation of SOI Scale SOI does not seem to index general sex drive or libido (discriminant validity) Could have strong sex drive within context of stable, committed relationship but not be willing to have uncommitted sex For couples in sexual relationship, no correlation between SOI scores and frequency of sex in last month for either men or women (Simpson & Gangestad, 1991) Higher SOI people self-report having sex earlier after relationship initiation than low SOI people Higher SOI people self-report more likely to have had sex with another person while dating current partner High SOI people report lower commitment to relationships This does not seem to be lost on their partners… Construct validity

Individual Differences in SOI Men (on average) reliably have higher SOI scores than do women, especially for attitude measures Expected from PI theory Men can convert short-term mating, multiple partners into offspring at much higher rate than women can However, within-sex variance in SOI scores tends to be greater than between-sex variance

SOI – Attitudinal Measures Notice that these do not tap actual sexual activity; could be very unrestricted attitude, but have little opportunity

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
