Study Notes

Understanding Psychology

Psychology is the scientific study of behavior and mental processes.
Key areas of study include brain damage effects on face recognition, childhood amnesia, obesity, and the impact of violence on children's aggression.

The Importance of Rewards in Behavior

A behavior is often strengthened when followed by a reward, known as the Law of Effect.
Reinforced behaviors are more likely to be repeated, while unreinforced behaviors tend to extinguish.
The Overjustification Effect suggests too much emphasis on external rewards can diminish intrinsic interest.

Research Methodology in Psychology

Research involves generating and testing hypotheses through experiments, correlations, measurements, and tests.
A hypothesis is a testable statement; a theory is a set of related propositions regarding a phenomenon.
The scientific method ensures that research is unbiased and reproducible.

Conducting Experiments

Experiments offer definitive insights into cause-and-effect relationships by controlling conditions and measuring variables.
Experimental groups receive the treatment; the control group does not.
Random assignment ensures equal likelihood of group placement, preventing bias.

Measurement and Statistical Analysis

Measurement assigns numerical values to variables; it facilitates data analysis.
Statistics help draw conclusions about populations from sampled data.
Statistical significance indicates that observed differences are unlikely due to chance.

Correlation Versus Causation

Correlation assesses whether one variable is associated with another.
Positive correlation means both variables move in the same direction, while negative correlation indicates an inverse relationship.
Correlation does not confirm causation; external factors may influence observed relationships.

Observation Methods

Direct observation involves watching a phenomenon in its natural setting.
Surveys gather self-reported data through questionnaires or interviews.
Social desirability bias can affect the honesty of self-reported behavior.

Ethical Considerations in Research

Ethical research involving humans must adhere to three principles: minimal risk, informed consent, and the right to privacy.
Participants should be fully informed about the study's nature and can withdraw at any time without penalty.

Nature vs Nurture Debate

The debate questions whether human traits are innate (nature) or shaped by experiences (nurture).
The nature perspective holds that individuals possess inherent knowledge.
The nurture viewpoint posits that knowledge and capabilities arise from interactions with the environment.
