Study Notes
Psychological Concepts
- Overconfidence: A cognitive bias where individuals believe they know more than they actually do, leading to misjudgments about their abilities.
- Hindsight Bias: The tendency to think that one could have predicted an event after it has already occurred, often leading to an inflated sense of foresight.
- Operational Definition: A clear specification of how variables are measured in a study, which facilitates replication.
Research Methods and Attitudes
- Scientific Attitude: Exemplified by critical questions like "What do you mean?" and "How do you know?", promoting skepticism and inquiry.
- Replication: Repeating a study to confirm findings, which increases confidence in the reliability of original research results.
Survey and Case Study Insights
- Wording Effects: Variations in survey phrasing can significantly influence responses, emphasizing careful wording in survey design.
- Case Study Method: Used by researchers like Jean Piaget to gather in-depth observations of unique individuals, though it may not represent broader populations.
Observational Techniques
- Naturalistic Observations: A research method involving direct observation of subjects in their natural environment to describe behavior without interference.
Correlation Concepts
- Prediction: Correlational research is primarily used for making predictions about relationships between variables.
- Positive Correlation: Higher levels of one variable (e.g., education) predict higher levels of another (e.g., income).
- Negative Correlation: An inverse relationship indicating that as one variable (e.g., wealth) increases, another variable (e.g., marital satisfaction) decreases.
Experimental Research
- Experimental Design: Involves manipulating one or more factors to determine their effects on a dependent variable, allowing for cause-and-effect conclusions.
- Placebo Effect: The phenomenon where participants experience real changes in their condition due to their expectations rather than the treatment itself.
Understanding Correlation and Causation
- Assuming Correlation Proves Causation: A common error where researchers mistakenly conclude that correlated variables have a direct cause-and-effect relationship.
Important Discoveries
- The Role of Expectations: Positive expectations can significantly impact outcomes, as seen in the placebo effect.
- Effectiveness of Research Designs: The most reliable way to establish the impact of a therapeutic method is through controlled experimental research, which allows for maximum control over variables.
