Document Summary
External validity-extent to which findings may be generalized. Volunteers- they differ from non-volunteers: they are more highly educated, higher ses, more in need of approval and more social, titles of studies also influences who signs up. Internet research- computers are used in certain demographics: urban/suburban areas, college educated, younger, higher income. A study examines the relationship between crowding and aggression among males and reports that crowding is associated with higher levels of aggression. Asians benefit more from support that comes with the comforts of proximity to friends rather than sharing. Aspects are similar across cultures: low waist-to-hip ratio along females were seen as attractive across some cultures- so results were generalizable. Any influence the experimenter has on subjects is constant throughout the study. There"s a possibility that the results are generalizable only to certain type of experimenters. Personality, gender and practice in the role affects the results.
