Study Notes
- Psychological research follows the scientific method, starting with a question and a theory.
- A theory in psychology is a comprehensive explanation for observations and predictions.
- Operationalizing questions involves turning general questions into measurable, testable propositions.
- Intuition is not always reliable, leading to hindsight bias and overconfidence.
- Hindsight bias refers to the tendency to believe one knew the outcome all along.
- Overconfidence can result in incorrect assumptions about people and their behavior.
- Case studies can be misleading due to their inability to be replicated and the risk of over-generalization.
- Naturalistic observation involves observing behavior in a natural environment without manipulation or control.
- Surveys and interviews are used to collect self-reported data and access conscious attitudes and beliefs.
- Correlation refers to the relationship between two variables and does not prove causation.
- Experiments involve manipulating an independent variable and isolating its effects to determine cause-and-effect relationships.
- Hypothesis: "Adult humans given caffeine will navigate a maze faster than humans not given caffeine."
- Caffeine dosage is the independent variable in the hypothesis.
- Experiments require random assignment of participants to control and experimental groups to minimize potential confounding variables.
- Double-blind procedures involve neither the researchers nor participants knowing which group is experimental and which is control to prevent unintentional influence on results.- An experiment is conducted to test the effect of caffeine on navigating through a corn maze.
- Three groups are formed: control (placebo), low dose (100 mg), and high dose (500 mg) of caffeine.
- The American Psychological Association is suggested to be consulted for obtaining informed consent from participants.
- Participants are released into the maze, and their time to complete it is recorded at the end.
- The results will be compared to determine if there is a significant difference in maze completion time between the groups.
- The experiment aims to contribute to the understanding of the effects of caffeine on cognition and potentially add to the scientific body of knowledge.
- The scientific method is employed to conduct psychological research, including case studies, naturalistic observation, surveys, interviews, and experimentation.
- Bias in experimentation is acknowledged and addressed through research practices.
