Document Summary
Ecological validity lab settings, constricts and limits. The idea is that regardless of the lab setting, the findings should still apply to the real world. Independent variable and then measure it by the dv. Located on the x-axis; studied vs. not studied for test. Located on the y-axis; reaction time, % correct, etc . Example: an individual is poked and then he/she turns to look at the distraction. Depends on the iv: dependent variable. Assumptions of science: determinism: lawful, orderly universe. Universe has order to it that we can discover: finite causation: limited # of factors. Assume there is a finite number of causes for a behavior. We can limit this to a couple of plausible explanations. Moves head = dv: multiple ivs can be present when an interaction occurs between variables, accuracy: correct/incorrect responses, reaction time (rt in msec) Ex: simple rt vs. choice rt: accuracy and reaction time. 250 ms = second (reaction to light)
