Mission and the Method

Earliest Social Psychology Experiments
- Norman Triplett (1897):
  - Indiana University professor, conducted first social psychology experiment.
  - Built a "competition machine" where 40 children wound a reel.
  - Found that children worked faster in teams compared to when they worked alone.
  - This effect is termed Social Facilitation, where presence of others enhances performance.
- Max Ringlemann (1880):
  - French professor of agricultural engineering who studied group dynamics.
  - Conducted an experiment where men pulled on a rope alone and together.
  - Discovered that as group size increased, individual effort decreased.
  - This phenomenon is referred to as Social Loafing, explaining why individuals may exert less effort in groups.
Introduction of Textbooks in 1908:
- William McDougall and Floyd Allport were key figures.

Gordon Allport (1954):
- Described attitudes as the most distinctive and indispensable concept in American social psychology.
- Observed dynamics of Study of the Self.
Kurt Lewin:
- Proposed that behavior is a function of both the person and the situation.

Behaviorism:
- Explained human behavior using learning principles such as rewards and punishments.
- Focused on observable actions.
Freudian Psychoanalysis:
- Focused on interpretations of individual experiences rather than experimental studies.

Defining Psychologists’ Roles:
- Aims for a broad understanding of human actions, thoughts, and feelings through the ABC Triad: Affect, Behavior, Cognition.
- Studies personal and situational influences on behavior.
- Emphasizes reactions to surroundings, and how circumstance changes behavior.
- Utilizes the scientific method to conduct experiments and test theories.

Anthropology:
- Study of human culture.
Economics:
- Focuses on the production, distribution, and consumption of goods and services.
Political Science:
- Examines political organizations and institutions.
Sociology:
- Studies human societies and group dynamics.

Psychology:
- The comprehensive study of human behavior.
Subfields of Psychology:
- Biological Psychology: Brain, nervous system, and bodily functions.
- Clinical Psychology: Focuses on abnormal behavior.
- Developmental Psychology: Examines changes across a lifespan.
- Personality Psychology: Analyzes differences between individuals and inner processes.

Curiosity About People:
- Edward E. Jones posits that curiosity is a universal trait.
- Understanding others does not require justification.
Philosophical Foundations:
- Philosophy is defined as the "love of wisdom" and involves systematic thinking.
- Aim to make the world better by understanding societal issues and proposing solutions.
Types of Research:
- Applied Research: Targets specific problems.
- Basic Research: Seeks to understand fundamental principles.

Scientific Method Steps:
- Identify problems for study.
- Formulate testable hypotheses.
- Design studies and collect data.
- Test hypotheses based on data, establishing a 5% significance threshold.
Common Wisdom:
- Common adages often contradict themselves (e.g., "opposites attract").
- Understanding the validity of human intuition through empirical testing.

Theories:
- Constructs logically linked, e.g., "need to belong in a group."
- Should be connected through observable variables and must be testable.

Variables in Research:
- Independent Variable (IV): Observable event that influences behavior.
  - Situational factors manipulated in experiments.
  - Individual Difference Variables: Characteristics like age that are measured, not manipulated.
- Dependent Variable (DV): Observable behaviors that result from the IV.
- Importance of operational definitions for clarity (operational definitions tie constructs to observable representations).

Experimental Studies:
- Researchers control procedures and randomly assign participants, allowing for cause-and-effect statements.
Quasi-Experiments:
- Lack random assignment but maintain some internal validity regarding the effect of IV on DV.
Laboratory vs. Field Experiments:
- Laboratory experiments allow control over extraneous variables.
- Field experiments take place in natural settings, offering local realism and generalization potential.
- Experimental Realism: Degree to which participants are engaged in the experiment, possibly forgetting it is an experiment.
- Mundane Realism: Extent to which the setting reflects real-world conditions.
- External Validity: How well findings generalize to broader contexts.

Correlational Approach:
- Observes relationships between variables.
- Correlation Coefficient (r): Indicates strength of the relationship (ranges from -1 to 1), with values closer to 1 indicating stronger relationships.
- Weakness of Correlation: It does not establish causation.

Self-Correcting Nature of Science:
- Replication efforts contribute to accurate findings across studies, emphasizing the reliability of results.
- Replication Crisis: Issues arise when studies fail to replicate or show diminished findings.
- Importance of preregistering studies to enhance transparency.
Open Science Movement:
- Aims for accessibility of study results to foster trust and reproducibility.
Concerns with Sample Diversity:
- Heavy reliance on student populations raises questions regarding generalizability to other age groups.
- Importance of replicating studies with diverse demographics.

Cultural Relativity:
- Acknowledges that Western cultures predominantly shape social psychology, though significant cultural differences exist and should be studied.

Longitudinal/Observational Studies:
- Pair individuals randomly and compare similarities and differences to assess effective variables.
