Chapter 2 What Makes Psychological Research Scientific? Theory – organized system of assumptions and principles that purports to explain certain phenomena and how they are related. o Many theories are tentative, pending more research or accepted by nearly all scientists. (theory of evolution) Hypothesis – statement that attempts to describe or explain a given behavior. Operational definitions – precise definition of a term in a hypothesis. Specifies how the phenomena in question are to be observed and measured. Principle of Falsifiability – predict what will happen as well as what will not. Confirmation Bias – the tendency to look for or pay attention only to the information that confirms one’s own belief. Descriptive Studies: Establishing the Facts Studies – select a group of participants to observe, preferably a representative sample (a group of participants that accurately represents the larger population that the researcher is interested in). Accurate representation will yield more accurate results than a large sample size. Case Studies – also, case history. Detailed description of a particular individual based on careful observation or formal psychological testing. Anything that provides insight into a person’s behavior.
