Document Summary
Psyc 1103 lecture 3 research methods in psychology. What one studies is not as important as how one studies it. It is the methods rather than the topics that make psychology a science. Should be grounded in a theory (will influence further steps of the process) Hypothesis : a testable prediction, in the form of a statement. Provide operational definitions of variables (definitions in context. Use statistical procedures to analyze data of experiment) Results should be able to be replicated. Ex: how the theory could be revised in future experiments. Improves reliability, helps theory to be further revised. Meta-analysis : combination of findings across multiple studies (increases reliability) Naturalistic observation : observing subjects in their natural environment. Pro: greater external validity (results can be generalized to real world) Con: no experimental control over variables of interest (no manipulation) Structured observation : observing subjects while manipulating certain variables. Con: artificial (can not be as easily generalized as naturalistic observation)
