01Research Methods

Operational definition: Exact procedure for measuring/manipulating a variable; makes concepts observable.
Independent variable (IV): Variable manipulated/selected by researcher; presumed cause.
Dependent variable (DV): Measured outcome; presumed effect.
Random assignment: Chance assignment to conditions; equalizes groups, supports causal inference.
Random sampling: Chance selection from population; supports generalization.

Common designs

Design	Key idea	Strength
Experiment	IV manipulated	Cause/effect
Correlational	Variables measured	Predicts; no causation
Naturalistic observation	Observe in real setting	High realism
Survey	Self-report	Fast, broad
Case study	In-depth single case	Rich detail

Correlation

r \in [- 1, 1]

Direction + strength; $r > 0$ positive, $r < 0$ negative, $r \approx 0$ no linear relation.

Correlation ≠ causation: Third variable, directionality, and selection effects can explain association.
Reliability: Consistency of measurement; same result across time/items/raters.

02Neurons & Brain

Endocrine system: Hormones in bloodstream; slower but longer-lasting than neural signaling.

Watch out:Broca's area: speech production; Wernicke's area: language comprehension.

Ex.Split-brain patient sees word in left visual field. Can they say it?

Usually no: right hemisphere gets it first; speech left hemisphere disconnected.

03Sensation & Perception

Sensation: Detection of physical energy by sensory receptors.
Perception: Organization/interpretation of sensory input.
Absolute threshold: Minimum stimulation detected 50% of the time.
Difference threshold: Minimum difference detected 50% of the time; just noticeable difference.

Weber's law

\frac{Δ I}{I} = k

$Δ I$ = threshold increment, $I$ = original intensity, $k$ = constant.

Signal detection theory: Detection depends on sensitivity + decision criterion; affected by expectations and fatigue.
Transduction: Conversion of physical energy to neural impulse.
Trichromatic theory: 3 cone types: red, green, blue; explains color detection.

04Learning

Operant consequences

Type	Effect on behavior	Example
Positive reinforcement	Increase	Add reward
Negative reinforcement	Increase	Remove aversive
Positive punishment	Decrease	Add aversive
Negative punishment	Decrease	Remove reward

Shaping: Reinforce successive approximations of target behavior.
Schedules: Fixed ratio = after set # responses; variable ratio = after unpredictable #; fixed interval = after set time; variable interval = after unpredictable time.

Watch out:Negative reinforcement is not punishment; it increases behavior by removing something unpleasant.

05Memory

Encoding: Getting information into memory.
Storage: Maintaining information over time.
Retrieval: Accessing stored information.

Memory models

Model	Components
Atkinson-Shiffrin	Sensory → short-term → long-term
Working memory	Central executive + phonological loop + visuospatial sketchpad
Levels of processing	Shallow to deep encoding

Sensory memory: Very brief register; iconic = visual, echoic = auditory.

06Cognition & Intelligence

Reliability vs validity: Reliable test can still be invalid; valid test must be reliable.

Watch out:Confirmation bias: seek evidence supporting existing belief, ignore disconfirming data.

07Development

Nature vs nurture: Genes and environment jointly shape development; interaction is typical.

Piaget stages

Stage	Approx age	Core
Sensorimotor	0–2	Object permanence
Preoperational	2–7	Symbolic thought; egocentrism
Concrete operational	7–11	Conservation; logical concrete
Formal operational	12+	Abstract reasoning

Assimilation: Fit new info into existing schema.
Accommodation: Change schema to fit new info.
Egocentrism: Difficulty taking another's perspective.

Erikson stages

Stage	Conflict
Trust vs mistrust	Infancy
Autonomy vs shame/doubt	Toddler
Initiative vs guilt	Preschool
Industry vs inferiority	School age
Identity vs role confusion	Adolescence
Intimacy vs isolation	Young adult
Generativity vs stagnation	Middle adult
Integrity vs despair	Late adult

08Personality & Disorders

Trait theory: Stable characteristics describe personality; e.g. Big Five: OCEAN.

Big Five

Trait	High end
O	Open to experience
C	Conscientious
E	Extraverted
A	Agreeable
N	Neurotic

Psychodynamic theory: Personality shaped by unconscious conflict; id, ego, superego.
Defense mechanisms: Unconscious ego strategies to reduce anxiety; e.g. repression, projection, rationalization.
Humanistic theory: Self-concept, free will, self-actualization; Rogers, Maslow.
Self-efficacy: Belief in ability to succeed at task.
Psychological disorder: Behavior/thoughts/emotions causing distress, dysfunction, danger.

Common disorders

Disorder	Core feature
Major depression	Persistent low mood/anhedonia
Bipolar	Depression + mania/hypomania
Anxiety disorders	Excessive fear/worry
OCD	Obsessions + compulsions
Schizophrenia	Psychosis; delusions/hallucinations
PTSD	Trauma re-experiencing + hyperarousal
