Document Summary
Individual differences: each person is diff from everyone else (even twins) Intrapersonal functioning: processes w/in person that lead you to act the way you do. Theory: proposed explanation/interpretation of the relations among constructs: set of ideas about how to think about class of events, testable, explain & predict new info. Yes. (need to figure out a way to measure personality) Good theory explains content, advance understanding (predict) Theories serve 2 functions: synthesizing function: organize and explain observations, heuristic function: generate predictions (eg. hypotheses) when tested, advance our understanding. Researchers must identify observable variables that reflect constructs of interest. Operationalization: translation of construct into a variables we can observe/measure. Construct: aggressiveness: operationalization: frequency and intensity of shocks given to a confederate, more shocks = more aggressive, eg. Construct: intelligence: operationalization: scores on an iq test, eg. Construct: self-esteem: operationalization: scores on a self-report measure of global self-worth, eg. Are operationalized (translated into observable variables) using several techniques:
