PSYCH 1 Chapter Notes - Chapter 1: Falsifiability, Postpositivism, Epigenetics
Document Summary
The scientific method : components and flow chart. Operationalization : reliability & validity falsifiability : the ability to find evidence that demonstrates your theory is wrong, start out with the presumption that your theory is wrong hypotheses : predictive statements based on your theory. H 0 = null hypothesis = if theory is not supported, then i expect _________. H a = alternative hypothesis = if theory is supported, then i expect. Experiments as causation (a/b + random assignment) correlations: way to measure how associated/related two variables are. Majority of psychological studies failed to show replication. Effect size : correlation (r); between groups (cohen"s d) correlations are small. Larger cohen"s d is equivalent to more different, less overlap. Availability : definition, examples, relevance to schema availability bias : the more available (memorable; apparent; recent) information, the more we will think about / use the information to influence decisions.
