PSYC 1010 Lecture 33 Notes
Introduction
Description
• Implies predictions that anyone can use to check the theory or to derive practical
applications
• Does people’s sleep predict their retention?
• Eventually, our research may (3) stimulate further research that leads to a revised
theory that better organizes and predicts what we know.
• As we will see next, we can test our hypotheses and refine our theories using descriptive
methods (which describe behaviors
• Often through case studies, surveys, or naturalistic observations), correlational methods
(which associate different factors)
• Experimental methods (which manipulate factors to discover their effects)
• To think critically about popular psychology claims, we need to understand these
methods and know what conclusions they allow.
• How do psychologists use case studies, naturalistic observations, and surveys to observe
and describe behavior?
• Why is random sampling important?
• The starting point of any science is description. In everyday life, we all observe and
describe people, often drawing conclusions about why they act as they do.
• Professional psychologists do much the same, though more objectively and
systematically, through
• Case studies (in-depth analyses of individuals or groups).
• Naturalistic observations (watching and recording the natural behavior of many
individuals)
• Surveys and interviews (asking people questions)
• Among the oldest research methods, the case study examines one individual or group in
depth in the hope of revealing things true of us all.
