Study Notes
Hindsight Bias
- Tendency to believe one knew the outcome of an event after it has occurred.
- Highlights the challenge in scientific research to predict outcomes in advance.
Applied Research
- Conducted to address practical problems with tangible applications.
- Distinct from basic research, which focuses on theoretical questions without immediate real-world relevance.
Basic Research
- Explores theoretical questions of interest to psychologists.
- Aims to expand knowledge without direct application or problem-solving focus.
Hypothesis
- Statement proposing a relationship between two variables.
- Includes independent variable (manipulated) and dependent variable (measured).
- Example: Watching violent TV is the independent variable affecting aggression (dependent variable).
Theory
- Framework aimed at explaining phenomena and guiding hypothesis formulation.
- Supports generation of testable hypotheses to collect data for validation.
Operational Definitions
- Specific explanations detailing how variables in a study will be measured.
- Essential for clarity in defining what constitutes violent programming and aggressive behavior.
Validity
- Research is valid when it accurately measures what it intends to.
- Important for ensuring accurate conclusions and data interpretation.
Reliability
- Research reliability refers to the consistency of results across replications.
- Reliable research produces similar outcomes under identical conditions.
Sampling
- Involves selecting participants for research studies.
- Aims to create a sample that accurately reflects the larger population for generalizability.
Population
- The complete group from which a sample is drawn.
- Represents anyone or anything eligible to be part of the study.
Random Selection
- Method ensuring every member of the population has an equal chance of being chosen.
- Enhances the representativeness of the sample and generalizability of results.
Stratified Sampling
- Technique ensuring specific representation of subgroups in a sample relative to the overall population.
- Useful for ensuring diverse demographic groups are proportionately included in research studies.
