Foundational Psychologists
Who framed which mental model.
01The idea
The MCAT is asking: which framework explains this phenomenon, and which thinker is associated with that framework? We will organize psychologists by what problem they were trying to solve.
THREAD · Structure → function
02Build the model
AStructuralism and functionalism: what is the mind for?
| Thinker | Contribution |
|---|---|
| Wilhelm Wundt | Structuralism: break conscious experience into components, by introspection. MCAT cares as historical origin, not modern use. |
| William James | Functionalism: mental processes exist to help organisms adapt; thoughts have survival value, behavior is purpose-driven. |
BBehaviorism: behavior without the mind
| Thinker | Contribution |
|---|---|
| Ivan Pavlov | Classical conditioning: stimulus–stimulus association |
| John B. Watson | Rejected introspection; psychology = observable behavior only |
| B.F. Skinner | Operant conditioning: reinforcement and punishment |
CPsychoanalytic theory: unconscious conflict
Sigmund Freud’s core ideas: unconscious drives; id, ego, and superego; defense mechanisms; and early childhood shaping personality. MCAT framing: unconscious motivation, and defenses such as repression, displacement, and projection.
Not modern science — but still testable.
DHumanistic psychology: growth and meaning
| Thinker | Contribution |
|---|---|
| Carl Rogers | Person-centered therapy; unconditional positive regard; self-concept alignment |
| Abraham Maslow | Hierarchy of needs; self-actualization |
ECognitive psychology: the mind as information processor
| Thinker | Contribution |
|---|---|
| Jean Piaget | Stages of cognitive development; schemas, assimilation, accommodation |
| Ulric Neisser | Mind as information processor: attention, perception, memory |
FLearning and social cognition
| Thinker | Contribution |
|---|---|
| Albert Bandura | Observational learning, modeling, self-efficacy: a bridge between behavior and cognition |
| Edward Thorndike | Law of Effect: behaviors followed by satisfaction are strengthened; a precursor to operant conditioning |
GEmotion and stress theories
| Thinker | Theory |
|---|---|
| William James | James–Lange: physiology precedes emotion |
| Walter Cannon | Cannon–Bard: simultaneous arousal and emotion |
| Stanley Schachter | Schachter–Singer: arousal + cognitive label = emotion |
HSocial psychology: situation over personality
| Thinker | Contribution |
|---|---|
| Solomon Asch | Conformity experiments |
| Stanley Milgram | Obedience experiments |
| Philip Zimbardo | Social roles; situational power |
ISociology and social structure (high-yield names)
| Thinker | Ideas |
|---|---|
| Émile Durkheim | Social facts; collective conscience |
| Max Weber | Verstehen (interpretive understanding); rationalization |
| Karl Marx | Class conflict; power and resources |

04Reason with it
Four questions. Answer in your head first, then choose. You’ll see the reasoning either way.
Think first.
A passage describes a child copying an adult’s aggressive behavior after watching it. Which thinker’s framework fits?
Think first.
Which thinker is linked to obedience experiments?
Think first.
A theory says people are inherently motivated toward growth and self-actualization. Which school is this?
Think first.
Which sociologist emphasized class conflict over power and resources?
05MCAT lens
The only way the MCAT uses these names
The MCAT does not ask dates, biographies, or random quotes
It asks which framework explains the behavior
And which theorist matches that framework
06Common traps
Trap 1: Psychologists are names to memorize
Misconception
They label explanatory lenses.
Correct model
Match the phenomenon to the framework first.
Trap 2: Behaviorists explain behavior through inner mental states
Misconception
They set mental states aside.
Correct model
Behavior is predicted from the environment and reinforcement.
Trap 3: Social psychology says personality explains behavior
Misconception
It emphasizes the situation.
Correct model
Situations often outweigh dispositions.
07Dependency check
Can you reconstruct this concept without looking at the page? You should now be able to reason through:
Which names explain behavior change
Check against 02 · B: Skinner, Pavlov.
Which names explain unconscious motives and growth
Check against 02 · C and D: Freud; Rogers, Maslow.
Which names explain cognition, development, and modeling
Check against 02 · E and F: Piaget; Bandura.
Which names explain emotion, social pressure, and structure
Check against 02 · G through I.
If something feels unclear, the missing idea is usually thisPsychologists are not random facts — they are labels attached to specific explanatory lenses.
08Remember
REMEMBER · if you keep only a few things
- Behavior change → Skinner, Pavlov
- Unconscious motives → Freud
- Growth & meaning → Rogers, Maslow
- Cognition & development → Piaget; observation & modeling → Bandura
- Emotion sequencing → James–Lange, Cannon–Bard, Schachter–Singer
- Social pressure → Asch, Milgram, Zimbardo; structure → Durkheim, Weber, Marx
09Forward hook
With the frameworks mapped, the last Psych/Soc topic is what happens when normally adaptive systems become dysregulated.
What defines a mental disorder, and how do disorders arise?
That leads to mental disorders.
