Document Summary
Sexual orientation p. 447-457 (not entire chapter) Self-labeling: we see a common finding: more men than women are exclusively homosexual. Gay men and lesbians are sex atypical in verbal fluency: gay men are usually gender atypical in their gender behaviour. They also perform more poorly in mental rotation tasks than heterosexual men. Also, homosexual men are better at object location than heterosexual men. Boys and girls who later become gay men an women engage less in gender-typical behaviours. Psychodynamic: attempts to explain development in terms of internal mental processes: rewards, punishment, socialization. Biological: attempts to explain development in terms of phenomena such as brain circuitry, hormones, genes, evolution. First proposed by freud: he believed that homsexuality was a permanent feature of an individual. 1960s, homosexuality was included in dsm and classified as a treatable disorder. o. Heterosexuality = normal end to psychosexual development: included homosexual phase in early childhood that was later forgotten.
