Sigmund Freud pictured the mind as an iceberg: a small conscious tip, a retrievable preconscious just below the surface, and a vast unconscious — threatening urges and memories actively kept out of awareness that nonetheless drive behavior.
Personality, for Freud, is three systems in constant negotiation:
When the id–superego conflict overwhelms the ego, it protects itself with unconscious distortions of reality. Repression — pushing threatening material out of awareness — is the master mechanism. The rest are the most testable items in this lesson:
| Mechanism | Logic | Example |
|---|---|---|
| Denial | Refuse to accept a reality | "I don't have a drinking problem" |
| Projection | Attribute your own unacceptable feeling to someone else | "You resent me" (when you resent them) |
| Displacement | Same feeling, safer target | Berated at work → snap at your roommate |
| Rationalization | Invent a self-justifying false explanation | "I failed because the test was unfair" |
| Reaction formation | Act out the opposite of the hidden impulse | Exaggerated hostility toward someone you're drawn to |
| Regression | Retreat to childish behavior under stress | An adult sulking and pouting after losing an argument |
| Sublimation | Channel the impulse into a socially valued activity | Aggression → competitive sports, surgery |
Ask three questions to tell them apart: did the target change (displacement)? Did ownership flip to another person (projection)? Did the impulse become something admirable (sublimation)?
Freud claimed personality forms as psychosexual energy focuses on different body zones: oral (0–18 months) → anal (18–36 months, toilet training) → phallic (3–6 years, the Oedipus conflict and identification with the same-sex parent) → latency (6–puberty) → genital (puberty on). Getting stuck at a stage — fixation — supposedly marks the adult: oral fixation → smoking, overeating, neediness; anal-retentive fixation → rigid, controlling, compulsively neat and stingy.
Two scientific verdicts to know: the theory is largely unfalsifiable (any outcome can be read as confirming it), and it rests on a handful of uncontrolled case studies rather than empirical evidence. Freud matters historically — the unconscious, talk therapy — not as a validated model.
Freud's followers kept the unconscious and childhood but dropped the fixation on sex.
Humanistic psychologists answered Freud's dark determinism with growth and free will. Abraham Maslow put self-actualization — realizing one's full potential — at the top of his hierarchy of needs, reachable once physiological, safety, belonging, and esteem needs are met.
Carl Rogers made the framework concrete. People need unconditional positive regard (UPR) — acceptance that does not depend on behavior. Raised with UPR, a person develops a healthy self-concept; raised with conditions of worth (love only if you meet standards), a person develops a gap between the real self (who you are) and the ideal self (who you feel you must be). A small gap is congruence — psychological health; a large gap is incongruence, which breeds anxiety and shaky self-worth.
A trait is a stable characteristic displayed across situations. Trait theorists describe and measure rather than explain origins. Gordon Allport catalogued thousands of trait words and distinguished a person's few broad central traits from a rare, life-organizing cardinal trait. Hans Eysenck boiled personality down to two or three biologically based dimensions, especially extraversion–introversion and emotional stability–instability.
The modern consensus is the Big Five — remembered as OCEAN:
| Dimension | High scorers | Low scorers |
|---|---|---|
| Openness | Imaginative, curious, variety-seeking | Conventional, routine-loving |
| Conscientiousness | Organized, disciplined, dependable | Impulsive, careless |
| Extraversion | Sociable, energized by people | Reserved, drained by crowds |
| Agreeableness | Warm, trusting, cooperative | Suspicious, antagonistic |
| Neuroticism | Anxious, emotionally reactive | Calm, secure |
The Big Five are substantially heritable, appear across cultures, and are remarkably stable across adulthood. Two traps: Openness is about new ideas, Extraversion about new people; Conscientiousness (organized) is not Agreeableness (warm).
Albert Bandura argued personality emerges from reciprocal determinism — a three-way loop in which behavior, personal/cognitive factors, and the environment continuously shape one another. You choose environments, which then act back on you.
Bandura's key personal factor is self-efficacy: belief in your capability to succeed at a specific task. It is not global self-esteem — it's "I can pass this exam." High self-efficacy fuels harder goals and persistence after setbacks.
Julian Rotter added locus of control: a generalized expectation about who controls your outcomes. An internal locus ("my effort determines what happens") predicts better achievement and coping; an external locus ("luck, fate, and powerful others decide") predicts passivity. Keep the pair straight: locus of control is a general expectancy (Rotter); self-efficacy is task-specific (Bandura).
Projective tests grow out of psychoanalysis: present an ambiguous stimulus and let the unconscious "project" onto it. The Rorschach inkblot test asks what you see in symmetrical blots; the Thematic Apperception Test (TAT) asks you to tell stories about ambiguous scenes. Their weakness is psychometric: different scorers reach different conclusions (low inter-scorer reliability), and results predict real behavior poorly (weak validity).
Objective inventories use standardized items with fixed responses scored by a key. The MMPI (Minnesota Multiphasic Personality Inventory) is the classic: a long true/false inventory used mainly to assess psychological disorders. It is empirically keyed — items were kept because they actually distinguished diagnostic groups in testing, not because they sounded relevant — and it includes validity scales that flag test-takers who may be faking. Objective beats projective on reliability and validity, which is why modern assessment leans on it.
1. (A) The id. The id is the unconscious reservoir of drives running on the pleasure principle — gratification now, consequences ignored. (B) the ego operates on the reality principle, negotiating compromises; (C) the superego is the moral conscience, the opposite of pleasure-seeking; (D) the preconscious is a level of awareness (retrievable material), not a personality structure; (E) the collective unconscious is Jung's concept, not part of Freud's structural model. Fix: "Wants it NOW" = id (pleasure principle); realistic compromise = ego; guilt and "should" = superego.
2. (E) Displacement. The anger belongs to the reviewer, but Victor redirects it onto a safer target — same feeling, new target. (A) projection would mean Victor attributes his own hostility to the roommate ("you're angry at me"); (B) reaction formation would have him acting exaggeratedly warm toward the reviewer; (C) rationalization would be inventing an excuse for the bad review; (D) sublimation would channel the anger into something socially valued, like a hard gym session. Fix: Same feeling + safer target = displacement; ownership flipped to the other person = projection.
3. (D) Unconditional positive regard. Affection contingent on achievement is the definition of conditions of worth — the opposite of the acceptance-regardless-of-behavior Rogers said children need. (A) positive reinforcement is a behaviorist term, and the parents did reinforce grades — that's exactly the problem Rogers flags; (B) self-actualization is a goal a person pursues, not something parents dispense; (C) locus of control is Rotter's concept about outcome expectations; (E) reciprocal determinism is Bandura's three-way causal loop. Fix: Love only IF you perform = conditions of worth; Rogers's antidote = unconditional positive regard.
4. (D) Conscientiousness. Organization, self-discipline, and dependability are the core of the C in OCEAN. (A) openness is imagination and novelty-seeking, not orderliness; (B) extraversion is sociability; (C) agreeableness is warmth and cooperation — a person can be organized but cold; (E) neuroticism is emotional reactivity, unrelated to deadlines. Fix: Organized/disciplined/reliable = conscientiousness; warm/cooperative = agreeableness — don't merge the two.
5. (B) Self-efficacy. Belief in one's capability to succeed at a specific task is Bandura's self-efficacy. (A) self-esteem is global self-worth, not task-specific confidence — the classic near-miss; (C) self-actualization is Maslow's realization of full potential; (D) the self-serving bias is an attribution pattern about successes and failures; (E) the ideal self is Rogers's "who I wish to be." Fix: "I can do THIS task" = self-efficacy; "I like myself overall" = self-esteem.
6. (A) An external locus of control. Crediting outcomes to luck and powerful others rather than one's own effort is Rotter's external locus. (B) an internal locus says "my effort decides" — the reverse; (C) high self-efficacy would assert capability, not futility; (D) reaction formation is a defense mechanism, not an expectancy; (E) unconditional positive regard is Rogers's parenting/therapy concept. Fix: Points outward (luck, fate, connections) = external locus; points at own effort = internal.
7. (B) An inherited reservoir of universal images and themes shared across humanity. That is Jung's collective unconscious, populated by archetypes recurring in myths and dreams. (A) describes Freud's personal unconscious; (C) describes the superego; (D) is Adler's compensation drive; (E) is Rogers's incongruence. Fix: Jung = collective (species-wide, inherited archetypes); Freud = personal (your own repressed history).
8. (E) The MMPI. It is standardized, objectively keyed, and includes validity scales built to catch faking — exactly the specification. (A), (B), and (D) are projective tests: subjectively scored, no validity scales, weak psychometrics; (C) free association is a psychoanalytic therapy technique, not a standardized measure at all. Fix: Standardized + objective scoring + fake-detection = MMPI; ambiguous stimuli = projective (and psychometrically weak).
9. (C) Scorers disagree and scores predict behavior poorly. Low inter-scorer reliability plus weak predictive validity is the decisive psychometric criticism. (A) administration time is a practical nuisance, not the core scientific problem; (B) is false — they are scored by human judgment, which is the problem; (D) reverses the tests' claim — they target unconscious material; (E) describes the MMPI's strength, misattributed. Fix: Judge any test on reliability (consistent scores) and validity (predicts behavior) — projectives fail both.
10. (E) Anal stage. Freud tied rigidity, control, and compulsive neatness to anal-retentive fixation from the toilet-training conflict. (A) oral fixation supposedly yields smoking, overeating, dependency; (B) phallic-stage issues concern the Oedipus conflict and identification; (C) latency is the dormant period — fixation traits aren't its signature; (D) the genital stage is mature sexuality, not a fixation profile. Fix: Rigid/controlling/neat = anal-retentive; mouth-centered habits and neediness = oral.
11. (C) Reaction formation. An unacceptable impulse (attraction) is converted into its conscious opposite (hostility) — the exaggerated, relentless intensity is the tell. (A) displacement would redirect a feeling onto a different target, but the target here is the same person; (B) projection would have Sofia believing the partner is attracted to her; (D) regression is retreating to childish behavior; (E) sublimation transforms the impulse into a socially valued activity. Fix: Behaving as the exact OPPOSITE of the hidden feeling = reaction formation.
12. (A) Adler — striving to overcome feelings of inferiority. Compensation for early weakness, and the inferiority complex when it fails, are Adler's signature ideas. (B) conditions of worth belong to Rogers, not Jung; (C) the collective unconscious is Jung's, not Horney's; (D) the inferiority complex is Adler's, not Jung's; (E) self-actualization belongs to Maslow (and Rogers), not Horney. Fix: Adler = inferiority/compensation; Jung = collective unconscious/archetypes; Horney = social roots of women's struggles + basic anxiety.
1. (A) The id. The id is the unconscious reservoir of drives running on the pleasure principle — gratification now, consequences ignored. (B) the ego operates on the reality principle, negotiating compromises; (C) the superego is the moral conscience, the opposite of pleasure-seeking; (D) the preconscious is a level of awareness (retrievable material), not a personality structure; (E) the collective unconscious is Jung's concept, not part of Freud's structural model. Fix: "Wants it NOW" = id (pleasure principle); realistic compromise = ego; guilt and "should" = superego.
2. (E) Displacement. The anger belongs to the reviewer, but Victor redirects it onto a safer target — same feeling, new target. (A) projection would mean Victor attributes his own hostility to the roommate ("you're angry at me"); (B) reaction formation would have him acting exaggeratedly warm toward the reviewer; (C) rationalization would be inventing an excuse for the bad review; (D) sublimation would channel the anger into something socially valued, like a hard gym session.

(A) openness is imagination and novelty-seeking, not orderliness; (B) extraversion is sociability; (C) agreeableness is warmth and cooperation — a person can be organized but cold; (E) neuroticism is emotional reactivity, unrelated to deadlines. Fix: Organized/disciplined/reliable = conscientiousness; warm/cooperative = agreeableness — don't merge the two.
5. (B) Self-efficacy. Belief in one's capability to succeed at a specific task is Bandura's self-efficacy. (A) self-esteem is global self-worth, not task-specific confidence — the classic near-miss; (C) self-actualization is Maslow's realization of full potential; (D) the self-serving bias is an attribution pattern about successes and failures; (E) the ideal self is Rogers's "who I wish to be." Fix: "I can do THIS task" = self-efficacy; "I like myself overall" = self-esteem.

(A) describes Freud's personal unconscious; (C) describes the superego; (D) is Adler's compensation drive; (E) is Rogers's incongruence. Fix: Jung = collective (species-wide, inherited archetypes); Freud = personal (your own repressed history).
8. (E) The MMPI. It is standardized, objectively keyed, and includes validity scales built to catch faking — exactly the specification. (A), (B), and (D) are projective tests: subjectively scored, no validity scales, weak psychometrics; (C) free association is a psychoanalytic therapy technique, not a standardized measure at all. Fix: Standardized + objective scoring + fake-detection = MMPI; ambiguous stimuli = projective (and psychometrically weak).
9. (C) Scorers disagree and scores predict behavior poorly. Low inter-scorer reliability plus weak predictive validity is the decisive psychometric criticism. (A) administration time is a practical nuisance, not the core scientific problem; (B) is false — they are scored by human judgment, which is the problem; (D) reverses the tests' claim — they target unconscious material; (E) describes the MMPI's strength, misattributed.

Fix: Rigid/controlling/neat = anal-retentive; mouth-centered habits and neediness = oral.
11. (C) Reaction formation. An unacceptable impulse (attraction) is converted into its conscious opposite (hostility) — the exaggerated, relentless intensity is the tell. (A) displacement would redirect a feeling onto a different target, but the target here is the same person; (B) projection would have Sofia believing the partner is attracted to her; (D) regression is retreating to childish behavior; (E) sublimation transforms the impulse into a socially valued activity.
