Coercion: when offered a large amount of money for example, have no choice but to do experiment. Sound mind- definitions on slide, but does not really define it,no number on it, just an idea. Hypothesis: skydivers will always score below 27 on mmse. After experiment, one skydiver scored 28, therfore hypotheis is wrong. Revised theory: skydivers are of less sound mind than other people. Independent variable- inputs to the experiment (group: find consenting skydivers (from club), and non skydivers (studnets, administer the mmse, compare the mmse. Skydivers got a lower score than controls, hypothesis is correct. Generalizability: questions whether something is true across individuals. Reliability: stability of observations across time, get the same answer at the same time. Objectivity; not influenced by emotions or personal views (racism, beliefs)
