Study Notes
Kitty Genovese Incident
- In March 1964, Kitty Genovese was stabbed and raped in New York City on her way home.
- The attack lasted 30 minutes and involved repeated stabbings.
- 38 neighbours heard the screams and pleas for help, but no one intervened.
- The incident sparked debate about the psychology of bystander apathy and the diffusion of responsibility.
The Scientific Method
- A systematic approach to understanding phenomena.
- Strives to minimize biases, personal beliefs, and emotions.
- Aims to identify questions of interest, gather information, form hypotheses, test hypotheses, analyze data, and build a body of knowledge.
Initial Observation and Question
- The Kitty Genovese incident sparked a question: Why did no one help?
Form Hypothesis
- A specific, testable prediction.
- Example: If multiple bystanders are present, then a diffusion of responsibility will decrease each bystander's likelihood of intervening.
Testing the Hypothesis
- Researchers created a simulated emergency in a laboratory setting.
- Undergraduates in separate rooms talked to each other via intercom.
- A confederate (researcher posing as a participant) faked a seizure, asking for help.
- The number of other participants the subject believed to be present was manipulated.
- The number of subjects who helped was measured.
Analyze Data
- Helping decreased as the perceived number of bystanders increased, supporting the hypothesis of diffusion of responsibility.
Further Research
- Additional studies supported the hypothesis in various situations.
- The findings led to the development of the theory of social impact.
Defining & Measuring Variables
- Variable: Any characteristic that can vary (e.g., stress, weight, reaction time).
- Operational definition: Defines a variable in terms of specific procedures used to produce or measure it.
Methods of Measurement
-
Self-report: Individuals report their knowledge, beliefs, feelings, and experiences.
- Can be gathered through interviews, questionnaires, and psychological tests.
- Limitations: Social desirability bias and interviewer bias.
-
Physiological: Measures biological responses.
- Examples: Blood pressure, hormonal secretions, brain activity.
- Limitations: Physiological responses do not always explain mental events.
-
Behavioral: Records observable actions.
- Requires coding systems for consistent measurement.
- Limitations: Observer bias and reactivity (changing behavior due to being observed).
- Unobtrusive measures help mitigate some limitations.
Methods of Research
-
Descriptive Research: Describes behavior in natural settings.
- Examples: Case studies, naturalistic observation, and surveys.
-
Correlational Studies: Examine relationships between variables.
- Do not establish cause-and-effect relationships.
-
Experimental Methods: Investigate cause-and-effect relationships.
- Involve manipulating an independent variable to observe its effect on a dependent variable.
Case Studies
- In-depth analysis of an individual's behaviors and experiences.
- Advantages: Useful for studying rare phenomena and providing a starting point for further research.
- Disadvantages: Limited generalizability and potential for researcher bias.
Naturalistic Observation
- Observing behavior in a natural setting.
- Advantages: Provides rich description of behavior in a real-world context.
- Disadvantages: Time-consuming, potential for researcher influence on behavior, and primarily descriptive (cannot explain "why").
Surveys
- Gather data from individuals through questionnaires.
- Widely used in many fields of psychology.
- Useful for describing attributes of a population.
- Population: Entire group of interest.
- Sample: Subset of the population selected to complete the survey.
Representative Sample
- Essential for drawing conclusions that apply to the entire population.
- Random sampling techniques (e.g., selecting every 10th person) help ensure a representative sample.
Hite Report (1987)
- Surveyed 100,000 women about their relationships.
- Found that most women were unhappy.
- The sample was not representative because only 1% of the survey recipients responded, leading to potential bias.
Correlational Research
- Studies relationships between variables.
- Goal is to determine if an association exists between variables.
- Does not establish causality.
- Variables are not manipulated, only measured.
Correlational Coefficient (r)
- A statistical measure of the strength and direction of the relationship between two variables.
- Ranges from -1.0 to +1.0.
Direction of Correlation
- Positive (+) indicates that both variables vary in the same direction (one increases, the other increases).
- Negative (-) indicates that variables vary in opposite directions (one increases, the other decreases).
Strength of Correlation
- The absolute value of the coefficient (ignoring the sign) indicates the strength of the relationship.
- Higher absolute values indicate stronger relationships.
- A correlation of 0.00 means no relationship.
Confounded Variables
- Unintended differences between conditions that can potentially influence the dependent variable.
- Can make it difficult to interpret experimental results.
- Critical to ensure that the independent variable, not a confounded variable, is responsible for any observed effects.
Placebo Effect
- Improved outcomes resulting from the expectation of improvement, even if the treatment is not effective.
- To control for the placebo effect, researchers often use control groups that receive a placebo (fake treatment) to compare their outcomes to the experimental group.
Validity and Reliability
-
Validity: How accurately an experimental procedure tests what it is intended to test.
- Is the study measuring what it claims to measure?
-
Reliability: How consistent the results are with other similar studies.
- Do the results replicate across multiple trials or studies?
