Study Notes
Longitudinal Studies
- Track individuals over a long period of time
- Useful for estimating stability and impact of experiences
- Disadvantages: cost, time commitment, attrition, practice effects
Cross-Sectional Studies
- Compare individuals of different ages at a single point in time
- More efficient and less expensive than longitudinal studies but don't capture stability of behavior
- May be affected by cohort effects
Longitudinal-Sequential Studies
- Combines elements of both longitudinal and cross-sectional designs
- Allows for flexibility in data collection
- Helps to mitigate cohort effects
Microgenetic Studies
- Examine developmental changes as they occur
- Frequent testing over short time periods (days or weeks)
- Focuses on small groups
- Expensive and repeated assessments may influence the changes being observed
Cross-Cultural Research
- Studies behavior across different cultures
Comparative Research
- Compares behavior in humans and non-humans
Psychophysiological Methods
- Focuses on the physiological basis of behavior
Experimental Research
- Manipulates variables to determine cause-and-effect relationships
- Independent variable (IV): manipulated by the researcher
- Dependent variable (DV): measured by the researcher and influenced by the IV
Experimental Research: Example of a Group Study
- Hypothesis: Watching Sesame Street improves reading ability
- IV: Hours of watching Sesame Street
- DV: Reading level test scores
- Four groups assigned to different viewing times (2, 4, 8, or 10 hours per week)
- Results: Increased viewing time is associated with higher reading level scores
Experimental Research: Other Experimental Designs
- Reversal Replication Design (ABAB): used when treatment can be reversed or withdrawn
- Multiple Baselines: used when variables can't be manipulated
- Quasi-experimental Studies: compares groups differing on some key characteristics (not manipulated)
Special Designs for Studying Age-Related Changes
- Longitudinal, cross-sectional, longitudinal-sequential, and microgenetic studies
Descriptive Research
- Focuses on describing phenomena
- Includes:
- Structured Interviews: provides rich data but relies on informant's knowledge and willingness to communicate
- Case Studies: detailed examination of an individual, often with clinical implications
Correlational Studies
- Examines relationships between variables as they occur naturally
- Uses correlation coefficient (r) to indicate the strength and direction of the relationship
Experimental Research: Example of an Experiment
- Tests null hypothesis and draws conclusions using inferential statistics
