PSYC 002 Lecture Notes - Lecture 2: Functional Fixedness, Confirmation Bias, Sunk Costs
Document Summary
Confirmation bias, mere exposure effect, and overconfidence: lack of meaning. Gambler"s fallacy, functional fixedness, placebo effect, bandwagon effect, hindsight bias: need to act quickly. Sunk cost, pre-crastination, stereotypes: how to know what needs to be remembered for later. Focus on one or few individuals, but hard to generalize to public: surveys. List of questions answered by research participants, but can have bias: natural observation. Observation of naturally occurring behavior w/o intervention: archival research. Using existing records to answer research questions, but no guarantee of consistency between records: longitudinal research. Data collected over long periods of time i. e. diseases that can be studied over a long period of time: cross-sectional research. Compares multiple segments of population at the same time i. e. compare 20 year olds to 30 & 40 year olds: quasi experiments. Unethical or unable to be reproduced, and therefore treatment cannot be compared: structured observation. People observed while doing set, specific tasks.
