Document Summary

Module 3: research strategies; how psychologists ask and answer. Theory: an explanation using integrated set of principles that organizes observations and predicts behaviours and events: linking facts with deeper principles, offer useful summary, must test theory"s, ex. Those who get good sleep tend to answer questions correctly. Hypothesis: a testable prediction, often implied by theory: specify what results would support theory and what results would disconfirm it. When sleep deprived people remember less than the day before: results will either confirm theory or lead us to revise or reject it. Our theories can bias observations: we may see what we want or expect. May view sleepy peoples answers as less insightful. To avoid bias psychologists report research with operational definitions of procedures and concepts: a carefully worded statement of the exact procedures used in research study. Sleep deprived may defined as x hours less than normal sleep hours.
