11.1 What Makes Personality Consistent Across Situations

  1. How it worksHow do trait, psychodynamic, humanistic, and social-cognitive theories each try to explain personality differently?
  2. Going furtherWhat happens to the idea of a fixed personality trait when the same person acts very differently across situations?
  3. Common mistakeWhy isn't personality just a label like introvert or extrovert with nothing in between?
Your turn1 of 2
One psychologist explains a person's helpfulness by pointing to a stable, measurable trait called agreeableness. Another attributes the same helpfulness to unconscious guilt being resolved through helping others. A third points to how the environment has consistently reinforced helping behavior in the past. Which three theoretical approaches to personality are being used, respectively?

11.2 Freud's Model of Id, Ego, and Superego

  1. How it worksHow do the id, ego, and superego each pull behavior in a different direction?
  2. How it worksWalk me through how the ego mediates between the id's demands and the superego's judgment.
  3. Common mistakeWhy isn't the id something a person can simply choose to switch off?
  4. Worked exampleFind which part of Freud's model, the id, ego, or superego, is winning when someone eats the whole cake despite feeling guilty about it.
Your turn1 of 2
Someone feels a strong urge to eat an entire cake, and despite feeling guilty about it, they eat the whole thing anyway. According to Freud's model, which part of the personality is 'winning' in this moment?

11.2 Freud's Psychosexual Stages and Fixation

  1. How it worksHow do Freud's oral, anal, phallic, latency, and genital stages each center on a different erogenous zone?
  2. Worked exampleFind which psychosexual stage Freud would link to an adult personality that's excessively neat and controlling.
  3. Common mistakeWhy has Freud's theory of fixation at a psychosexual stage largely fallen out of favor with modern researchers?
Your turn1 of 2
According to Freud, an adult who is excessively neat, rigidly controlling, and stubborn about order and cleanliness would most likely be linked to unresolved conflict during which psychosexual stage?

11.2 Defense Mechanisms Protecting the Ego

  1. How it worksHow does repression push an unacceptable thought out of conscious awareness entirely?
  2. How it worksWalk me through how projection and displacement each redirect an uncomfortable feeling somewhere else.
  3. Going furtherWhat happens to a defense mechanism's usefulness when it's relied on constantly instead of occasionally?
  4. Worked exampleFind which defense mechanism explains a person mistreated at work coming home and snapping at their family instead.
Your turn1 of 2
After being harshly criticized by their boss at work, someone comes home and snaps angrily at their family over a minor, unrelated issue, even though the family did nothing to provoke this level of anger. Which defense mechanism does this best illustrate?

11.3 Jung, Adler, and Horney Against Freud

  1. How it worksHow does Jung's collective unconscious differ from Freud's personal, individual unconscious?
  2. How it worksWalk me through how Adler's striving to overcome inferiority replaces Freud's sexual drive as the core motivator.
  3. Going furtherWhat did Horney argue was wrong with Freud's theories about the psychology of women specifically?
Your turn1 of 2
Freud proposed an unconscious mind built entirely from an individual person's own repressed personal experiences. Jung instead proposed an additional, deeper layer of the unconscious containing universal symbols and themes shared across all of humanity, not tied to any one person's personal history. What is Jung's concept called, and how does it differ from Freud's?

11.4 The Behavioral and Social-Cognitive View of Personality

  1. How it worksHow does a social-cognitive theory explain personality forming through reinforcement, punishment, and observation?
  2. How it worksWalk me through Bandura's reciprocal determinism linking behavior, environment, and personal factors in a loop.
  3. Going furtherWhat happens to someone's future behavior when they develop an internal versus an external locus of control?
Your turn1 of 2
A shy student avoids raising their hand in class (behavior), which leads teachers to call on them less often (environment), which further reinforces the student's belief that they aren't a good public speaker (personal factor), which then makes the student even less likely to volunteer answers in the future. What concept does this ongoing loop illustrate?

11.5 Maslow, Rogers, and the Humanistic Self

  1. How it worksHow does Rogers's unconditional positive regard help someone develop a healthy sense of self?
  2. Common mistakeWhy isn't self-actualization the same thing as simply achieving fame or wealth?
  3. Going furtherWhat happens to someone's self-concept when there's a large gap between their real self and their ideal self?
Your turn1 of 2
A parent consistently loves and accepts their child fully, even when the child makes mistakes or falls short of expectations, never making that love feel conditional on the child's specific achievements or behavior. According to Rogers, what does this kind of acceptance help the child develop?

11.7 The Five-Factor Model of Personality

  1. How it worksHow do openness, conscientiousness, extraversion, agreeableness, and neuroticism each capture a different dimension of personality?
  2. Worked exampleFind where someone who is highly organized, calm under pressure, but reserved in groups would score on each of the five factors.
  3. Going furtherWhat does twin research suggest about how much of each Big Five trait comes from genetics versus environment?
  4. Common mistakeWhy isn't introversion on the Big Five the same thing as shyness or social anxiety?
Your turn1 of 2
For a specific Big Five trait, identical twins show a personality correlation of 0.539, while fraternal twins show a correlation of 0.247 on the same trait. Using heritability = 2 times (identical-twin correlation minus fraternal-twin correlation), what is the estimated heritability of this trait, as a decimal?

11.8 Individualism, Collectivism, and Personality Across Cultures

  1. How it worksHow does an individualist culture's definition of a healthy personality differ from a collectivist culture's?
  2. Going furtherWhat happens to a personality trait like extraversion when the very concept of the self is defined differently across cultures?
  3. Common mistakeWhy isn't one culture's model of a healthy personality simply the universal, correct one?
Your turn1 of 2
In one culture, a psychologically healthy adult is often described as independent, self-reliant, and comfortable standing out from the group. In a different culture, a psychologically healthy adult is often described as interdependent, attentive to group harmony, and comfortable blending in with others. What does this contrast best illustrate?

11.9 Self-Report Inventories and Projective Tests

  1. How it worksHow does a self-report inventory like the MMPI score personality using a person's own answers to structured questions?
  2. How it worksWalk me through how a projective test like the Rorschach or the TAT is supposed to reveal unconscious material?
  3. Common mistakeWhy isn't a projective test's interpretation as reliable and valid as a well-built self-report inventory?
  4. Going furtherWhat happens to a self-report inventory's accuracy when a job applicant answers to look as favorable as possible?
Your turn1 of 2
A clinician places equal confidence in a client's score on a well-validated self-report personality inventory and in their own subjective interpretation of the same client's Rorschach inkblot responses, treating both as equally scientifically reliable and valid. What is the concern with this equal treatment?
