Study Notes
Key Psychological Research Concepts
- Hindsight Bias: The inclination to believe an event was predictable after it has occurred; commonly expressed as "I knew it all along."
- Applied Research: Focuses on real-world applications, addressing practical issues and challenges.
- Basic Research: Curiosity-driven investigation intended to enhance understanding without immediate practical application.
- Variables: Elements that can change or vary, influencing research outcomes.
Experimental Design Terminology
- Independent Variable: The manipulated factor in an experiment aimed at observing its effects on the dependent variable.
- Dependent Variable: The outcome measured in an experiment that is expected to change based on the independent variable's manipulation.
- Validity: The extent to which research accurately measures its intended variables.
- Reliability: The consistency of a research study’s results across multiple trials.
Participant and Sampling Methods
- Participants: Individuals involved in a study; the subjects under investigation.
- Sampling: The method by which participants are selected for study.
- Population: The complete group from which a sample is drawn for research; represents a broader context.
Types of Sampling
- Random Selection: Ensures every individual has an equal chance of being chosen, enhancing sample representativeness.
- Stratified Sample: A sampling method ensuring specific subgroups are proportionately represented based on key characteristics.
Experiment Types
- Laboratory Experiments: Controlled experiments conducted in a managed environment for precise measurement.
- Field Experiments: Studies carried out in natural settings; less control but greater ecological validity.
Experimental Challenges
- Confounding Variable: External factors that may inadvertently affect results, complicating the interpretation of findings.
- Assignment: The method of grouping participants in an experiment. Random assignment minimizes pre-existing group differences.
- Participant-Relevant Confounding Variables: Individual differences among participants that can skew results.
- Situation-Relevant Confounding Variables: Environmental factors that may influence outcomes when groups experience differing conditions.
Biases in Research
- Experimenter Bias: A form of bias where researchers inadvertently influence their outcomes; can be minimized through double-blind procedures.
- Participant Bias: Changes in behavior due to awareness of being observed; reduced using single-blind procedures.
- Demand Characteristics: Cues that signal the study's purpose, possibly altering participants' responses.
Key Experimental Components
- Experimental Group: The group receiving the treatment in an experiment.
- Control Group: The group not subjected to treatment, used as a reference to evaluate experimental outcomes.
- Hawthorne Effect: Changes in behavior when participants know they are part of an experiment.
Study Design Techniques
- Placebo Effect: Improvements resulting from the expectation of treatment rather than the treatment itself.
- Order Effects: Variations in results caused by the sequence in which treatments are administered.
- Counterbalancing: A design technique that uses subjects as their own controls to minimize extraneous variables.
Correlation and Research Methods
- Correlation: Assessing the relationship between two variables, showing how one may predict the other.
- Positive Correlation: Indicates that one variable's presence suggests the other is also present.
- Negative Correlation: Indicates that one variable's presence suggests the absence of the other.
Additional Research Approaches
- Ex Post Facto Study: Research design that looks at existing differences rather than manipulates variables.
- Survey Method: Collects self-reported data from a representative sample through questions.
- Naturalistic Observation: Observing behavior in natural contexts without interference.
- Case Study: An in-depth exploration of a single subject to derive broader insights.
- Theory: A structured explanation that organizes observations and underpins hypothesis generation.
- Operational Definition: Specific procedures for measuring variables, critical for replicability and clarity.
- Replication: Repeating studies to validate findings across different contexts or populations.
- Experiment: A method involving manipulation of variables to observe effects on behavior or mental processes.
