Document Summary

Part 1: citations and support to the claims, very vague lies on anecdotal evidence, pg. Placebo response: clear definition, reduces to simplistic concepts, it cannot be disproven. Part 2: describe participants briefly number or demographic (1) Subliminal tapes for memory and self esteem. Filled out pre and post test: general improvement of self esteem. Placebo effect: no, there is a placebo. Comparing different groups: different subjects each condition, ex. quiz findings from 12 pm to 1 pm seminar. We have to use them for subject variables: ex. difference of brain activity between males and females. Studies commonly involve deception: ex. studies of eye witness observations, quiz the students on the individual who bursts in. Cannot run the study with same participants twice. Need larger numbers than within-subject: ex. comparing recall for semantically related words vs. unrelated. Between: n = 60, 30 for each condition. Within would only require one group of 30.
