Introduction to Research Methods00:00:00
Psychologists utilize diverse research techniques beyond common sense to gather data and draw logical, evidence-based conclusions about human behavior.
Experimental and Case Studies00:01:11
Experiments allow for the determination of cause-and-effect relationships by manipulating variables. Case studies, such as those of Phineas Gage or Genie, focus on in-depth analysis of single subjects or specific situations to understand human development and brain function.
Correlational Studies and Surveys00:03:16
Correlational studies identify relationships between variables without implying causation, often used when experiments are unethical. Surveys are described as a quick, effective method for gathering large amounts of data from a broad population.
Longitudinal and Cross-Sectional Studies00:04:59
Longitudinal studies track subjects over long periods to observe development, whereas cross-sectional studies compare different age groups at a single point in time to analyze population characteristics.
Naturalistic Observation00:06:25
Naturalistic observation involves studying subjects in their real-life environments when laboratory settings would be impractical or would alter natural behavior.
