    Structuralism

    Functionalism

    Behaviorism

    Humanistic Psych

    Psychoanalytic

    Titchner

    Introspection

    Finding structures of the mind

    Too vague

    William James & Darwin

    Processes

    Evolution of how they work

    Watson & Skinner

    Observable behavior

    Objective study (no introspection)

    Conditioning

    Rogers & Maslow

    Positive psych

    Potential for growth

    Freud

    Unconscious mind and childhood shape behavior

    Sex and aggression

  • Hindsight bias: evidence supporting the idea is obvious, “I knew it all along”

  • Overconfidence: overestimating abilities

  • Perceiving patterns in random events

  • Hypothesis is a testable prediction, often connected to a theory

  • Case studies examine an individual or group

  • Naturalistic observation watches people with no involvement

  • Surveys ask people to answer questions

  • Correlation does not equal causation

  • 68% of data falls within one standard deviation

  • Statistically significant: not likely due to chance

  • Independent variable is changed

  • Dependent variable is measured

  • Confounding variables affect experiments

  • Random sample, random selection, random assignment (experimental or control)

  • Inter-rater reliability: consistency of when different people administer the same test to same subject

  • Nervous system communicates through neurons

  • Transmit action potentials

  • Selectively permeable membrane, negative inside and positive outside

  • Excitatory signals (GO) and inhibitory signals (STOP)

  • During the refractory period, a neuron cannot fire again until it “resets”

  • Agonists increase neurotransmitter actions

    • Block reuptake or increase production

    • Amplify responses

    (ACh)

    Enables muscle action, learning, and memory

    ACh-producing neurons fail (Alzheimer's)

    Dopamine

    Too much → schizophrenia

    Not enough → tremors, decreased mobility

    Serotonin

    Affects mood, hunger, sleep, and arousal
