Study Notes

Foundations of Psychology

Psychology is the scientific study of the mind and behavior.
Structuralism focuses on understanding consciousness through introspection; founded by Wilhelm Wundt, who established the first psychology lab and authored the first psychology textbook.
Functionalism, championed by William James, examines how mental activities facilitate adaptation to environments.
Psychoanalytic Theory, developed by Sigmund Freud, highlights the influence of the unconscious on conscious thoughts and behavior.
Gestalt Theory suggests that human perception is holistic, credited to Wertheimer, Koffka, and Kohler.
Behaviorism emphasizes the observation and control of behaviors; key figures include Pavlov, Watson, and Skinner.
Humanism asserts the inherent potential for goodness in all individuals, pioneered by Abraham Maslow and Carl Rogers.

Key Theorists and Concepts

Wilhelm Wundt: One of psychology's founders, recognized for experimental methods, focusing on conscious experience.
William James: The first American psychologist, associated with Functionalism and the study of behavior function.
Sigmund Freud: Originated Psychoanalysis, emphasizing unconscious processes influenced by childhood events.
John B. Watson: The father of Behaviorism, prioritized observable behavior over introspection.
B.F. Skinner: Known for his work on the relationship between behavior and consequences, especially through reinforcement.

Maslow's Hierarchy of Needs

Hierarchy consists of five levels:
- Physiological (basic needs)
- Safety (security)
- Social (connections)
- Esteem (respect)
- Self-Actualization (fulfillment of potential)

Branches of Psychology

Developmental Psychology: Explores physical and mental changes across the lifespan, including moral reasoning and social skills.
Health Psychology: Studies the interplay of biology, psychology, and socio-cultural factors on health.
Social Psychology: Investigates how individual interactions influence behavior and social norms.
Personality Psychology: Focuses on conscious and unconscious thought patterns and personality traits (O.C.E.A.N: Openness, Conscientiousness, Extraversion, Agreeableness, Neuroticism).
Clinical Psychology: Manages diagnosis and treatment of psychological disorders.
Industrial-Organizational Psychology: Applies psychological principles in workplace environments.
Sports & Exercise Psychology: Addresses psychological factors and performance in sports.

Research Methods

Naturalistic Observation: Records genuine behaviors in their natural settings.
Surveys: Collects data from diverse populations efficiently.
Longitudinal Studies: Observes the same subjects over time to track changes.
Cross-Sectional Research: Compares different age groups or segments at a single time.
Archival Research: Analyzes existing data for emerging patterns and relationships.

Experimental Design

Control Group: Participants not exposed to the manipulated variable.
Experimental Group: Participants exposed to the manipulated variable.
Independent Variable: The manipulated factor in an experiment.
Dependent Variable: The outcome measured to assess the effect of the independent variable.
Placebo Effect: The influence of participants' expectations on their experience in experiments.
Ethics: Certain questions can't be ethically studied through experimental methods (e.g., subjecting participants to harm).

Neuropsychology and Behavior

Biopsychology: Links biological processes to behavior, emphasizing the nervous system's structure and function.
Genetics: Investigates how genetic factors influence physiological and psychological traits.
Neurotransmitters: Chemicals that transmit signals, crucial for brain communication, with specific roles such as:
- Dopamine: Affects mood, learning, and sleep.
- Serotonin: Impacts mood and sleep patterns.
- Acetylcholine: Involved in muscle action and memory.

Brain Structure and Function

The Cerebral Cortex provides higher-level processing, while specific areas serve specialized functions:
- Motor Cortex: Involved in movement planning.
- Prefrontal Cortex: Manages higher-level cognitive processes.
- Broca’s Area: Essential for language production.
- Wernicke’s Area: Involved in language comprehension.
- Temporal Lobe: Associated with hearing and memory.
- Occipital Lobe: Responsible for visual processing.

Miscellaneous Concepts

Single-Blind Study: Participants are unaware of their group assignment.
Double-Blind Study: Both researchers and participants are unaware of group assignments to reduce bias.
Institutional Review Board (IRB): Reviews research proposals involving human subjects to ensure ethical standards.
Reliability and Validity: Fundamental statistics ensuring experiments consistently yield accurate results.

These notes encapsulate key concepts and figures in psychology, along with foundational theories, research methodologies, and brain functionality, providing a comprehensive review for study.
