PSYCH 100 1st Edition Lecture 3Outline of Last Lecture I. Research StrategiesII. Psychology and the Scientific MethodIII. Research MethodsOutline of Current Lecture I. ExperimentationII. Experimental ResearchIII. Ethical Issues in ResearchCurrent LectureI. ExperimentationA. How would you operationalize a hypothesis?B. Correlation does not equal causationC. Experimentation- Manipulation of one variable (IV) to observe effect on other variable (DV).1. Independent Variable- IV. Dependent Variable (DV)2. Need random assignment and control group for experimentation3. Control Group- to observe naturally what happens, used to compare experimental manipulation, used as a base.D. Random Assignment to Condition- every condition has various assortment of participants, so to not act on confirmation biases of researchers.1. computer program randomly assign participants to various independent variables E. Sample Size- the more participants leads to more accurate and evened out data. 1. Statistical Significance- Difference not likely due to chance, certain of outcome. II. Experimental Research. These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.A. Limitation of Experimental Research is sometimes participants behave different in anexperiment, tendency to try to “help” researchers and act in a way that is “expected”. Cannot test everything experiementally. B. Benefit of Experimental Research- to infer causality III. Ethical Issues in ResearchA. Ethical standards are surprisingly highB. IRB (Institutional Review Board)- Decides if a study is ethicalC. Deception often necessary to get data from research participants, and aims to minimize harmD. Informed Consent- Consent from participants is essentialE. Debriefing- “This is what we are really studying” Researchers tell participants the purpose of the study.F. Confidentiality- guarantee to participants that information from study will not be associated with
