Study Notes

Introduction to Psychology - Study Notes

Psychology Defined: The scientific study of behavior and mental processes. Began in 1879, evolving from ancient Greek philosophical roots.
Science of Psychology: Focuses on observable actions (behavior) and internal processes (mental processes).
Goals of Psychology: Describe, explain, predict, and control behavior and mental processes.
Levels of Analysis: Examines behavior from different perspectives: brain (cellular/molecular), individual, group interactions.
Enduring Issues: Recurring topics in psychology, including:
- Person-Situation Interaction
- Internal vs. External Factors
- Nature vs. Nurture
- Stability vs. Change
- Diversity vs. Universality
- Mind-Body Connection
Divisions in Psychology: Clinical/Counseling, Cognitive, Developmental, Experimental, Industrial/Organizational, Social Psychology.

History of Psychology

Ancient Roots: Psychology emerged from philosophical inquiry in ancient Greece (Plato, Socrates, Aristotle).
Scientific Beginnings: William Wundt established the first psychological laboratory in Leipzig, Germany in 1879.
- Focused on studying the conscious mind.
Structuralism: Led by Edward B. Titchener (Wundt's student), aimed to analyze basic elements of the mind through introspection. Compared psychology to chemistry.
Functionalism: Pioneered by William James, focused on the "why" of mental processes, inspired by Darwin's theory of evolution. Used stream of consciousness as a concept.
Gestalt Psychology: German psychologists who opposed structuralism, emphasized the whole as more significant than the sum of its parts. Example includes the phi phenomenon.
Psychoanalysis: Developed by Sigmund Freud, emphasized the unconscious mind and the influence of early childhood experiences on behavior, emphasizing repressed memories and sexual urges.
Behaviorism: Focused on observable behaviors, dismissing the unobservable conscious mind, exemplified by Watson and Skinner (radical behaviorism) and his famed Skinner box experiments.
Humanism: Emphasized the potential for personal growth and fulfillment, promoting a positive approach to psychology, using concepts such as self-actualization. Advocated by Carl Rogers and Abraham Maslow.

Experimental Psychology & Statistics

Scientific Method Components:
- Defining a research problem
- Formulating hypotheses
- Designing research studies
- Analyzing data
- Reporting results
- Developing theories.
Key Scientific Components:
- Events: Observable phenomena.
- Hypotheses: Specific predictions about events.
- Variables: Measurable factors.
- Operational definitions: Precise descriptions of variables.
- Theories: Explanation for observed events.
Research Methods:
- Case studies: In-depth analysis of one individual.
- Naturalistic observation: Observing behavior in its natural environment.
- Surveys: Collecting data through questionnaires/interviews.
- Correlational studies: Examining relationships between variables, but not cause-and-effect.
- Experiments: Manipulating variables to determine cause-and-effect relationships.
Correlation and Causation: Correlation does not equal causation.
Statistics:
- Samples and populations: Selecting study groups.
- Correlation coefficients: “r,” measures the strength and direction of relationships (-1 to +1).
- Probability and p-values: Assess the likelihood results occurred by chance, with smaller values being more significant.
- Controlled Experiments: Designed to isolate cause-and-effect relationships, employing random assignment, controls, and independent variables (IV), dependent variables (DV). Importance of placebos, double-blind studies to avoid experimenter bias.
- Reliability and Validity: Consistency and accuracy (a reliable measure is not always valid).

Biological Psychology

Behavioral Neuroscience: Studies the brain and its role in behavior.
Nervous System:
- Central Nervous System (CNS): Brain and spinal cord.
- Peripheral Nervous System (PNS): Nerves outside the CNS.
  - Somatic nervous system: Controls voluntary movements.
  - Autonomic nervous system (ANS): Controls involuntary functions (sympathetic/parasympathetic).
Neurons:
- Structure (soma, dendrites, axon, myelin sheath, terminals).
- Electrical signaling and action potential.
- Electrochemical communication at synapses (neurotransmitters, receptors, reuptake).
Brain Regions:
- Cerebral Cortex (four lobes, including frontal, parietal, temporal, and occipital; their functions in the brain)
- Subcortical Structures (thalamus, limbic system, hippocampus, amygdala, hypothalamus).
- Midbrain (reticular formation, substantia nigra).
- Hindbrain (medulla, pons, cerebellum).
Brain Imaging Techniques: EEG, CAT, PET, MRI, fMRI (used to study the brain and diagnose issues).
Brain Plasticity: The brain's ability to change and adapt. Damage or skill learning impact this.
