Document Summary

The scientific processes: understanding research, important for critical thinking, necessary to be a sophisticated consumer of psychological information. Study design: experimental design: randomly assign participants to valium or placebo group & compare memory abilities. Collect data: administer memory tests to 24 participants on valium & 24 participants on placebo. Analyze & interpret data: memory performance is worse in valium group than placebo group. Report findings: publish in a journal (ex: psychopharmacology) If it be counted or scored then you have achieved an operational definition. Single-blind study (experimenter doesn"t know but participants do know): line on the bottom. Also single-blind: middle line experimenter knows & participants don"t. Double-blind study: top line- none of them know. Unblinded study: experiment dealing with old people: the participants know what the condition is & so does the researcher. Sometimes developmental psychologists use this method to study children by setting up cameras at different settings of child"s life to see how they act.
