PSYB01H3 Chapter Notes - Chapter 2: Facial Feedback Hypothesis, External Validity, Science Advances
Document Summary
Experimental design: manipulate independent variable and control other variables; only it allows for testing of cause and effect relationship. Non experimental design: quasiexperimental, correlation, survey, single-subject or small-n research. Paul ekman: nonexperimental studies of facial expression across cultures led to experimental studies on it. Conceptual definition: provides meaning of an abstract term, semantic or linguistic meaning. Operational definition: indicates how a concept is coded, measured or quantified ex facial action coding system. Both prediction and establishing cause and effect. Basic research: addresses fundamental questions about the nature of abstract psychological processes and ideas like emotion intelligence reasoning and social behaviour. Applied research: addresses questions to solve relevant problems: ex. Program evaluation: studies the effects on behaviour of large scale policy changes, social reforms and innovations. Both are linked in a continuum and build on each other. Often observations have to be broken down into simpler units so they can be quantified and measured.
