PSY210H1 Chapter Notes - Chapter 2: Informed Consent, Cortisol, Cultural Psychology
Document Summary
Hypotheses are tested in experimental investigations: theories organize research findings and guide new research. Objectivity and measurement: to achieve objectivity: Accurately define them so they can be measured. Three types descriptive, correlational, and experimental. Descriptive research: research based solely on observations, with no attempt to determine systematic relations among the variables, observational methods. Minimizing observer bias clearly identify and define behaviours, have multiple independent observers view same behaviour. Observer influence = the effects of knowing you are being observed. Structured observation = observation of behaviour in settings that are controlled by the investigator: interview methods. Open-ended interviews can be studied qualitatively for themes that emerge. Also, some researchers use a questionnaire: case studies. A research method that involves only a single individual, often with a focus on a clinical issue. Correlational research: attempts to identify correlations among variables, correlation = relation between two variables. Positive correlation = two variables changes in the same direction.
