Study Notes
Psychological Research Key Concepts
- A theory is a comprehensive framework that explains observed phenomena through a well-developed set of ideas.
- Inter-rater reliability evaluates the consistency of observations made by different observers, enhancing credibility in research findings.
- Experimental research design is crucial for establishing cause-and-effect relationships, as it manipulates variables to observe outcomes.
- Confirmation bias is a cognitive bias where individuals tend to overlook or dismiss evidence that contradicts their existing beliefs or ideas.
- A basic experiment must involve at least two participant groups to effectively compare different conditions or influences.
- The placebo effect demonstrates that mere anticipation of an event can influence actual outcomes, showcasing the power of expectations in psychological studies.
- The independent variable is the variable that the experimenter controls or manipulates, essential for assessing its effect on the dependent variable.
- In research by Harrison et al., negative emotions are considered the dependent variables, as they are the outcomes assessed in relation to the condition of the participants (depressed vs. non-depressed).
- Validity refers to the accuracy of a measurement tool, indicating whether it effectively measures the intended construct or variable.
