6.4 Identity Formation: Developmental Theories & Social Influences
Key Takeaways
- Cooley's looking-glass self holds that identity forms from our imagination of how others judge us — the self is built from perceived appraisals, which may be inaccurate.
- Mead's stages of self-development move from imitation, to play (taking one role at a time), to game (coordinating many roles), culminating in the generalized other.
- Mead distinguishes the 'I' (spontaneous, unsocialized actor) from the 'Me' (the socialized self that reflects internalized societal expectations).
- Kohlberg's three levels — preconventional, conventional, and postconventional — are scored by the *reasoning* a subject gives, never by the choice they make.
- A reference group is any group used as a standard for self-evaluation, and it need not be a group the individual actually belongs to.
6.4 Identity Formation: Developmental Theories & Social Influences
Section 6.2 defined what the self-concept contains. This section addresses AAMC Content Category 8A's second topic — how that self gets built. The AAMC lists three drivers explicitly: theories of identity development, the influence of social factors (individuals and groups), and the influence of culture and socialization. Psych/Soc passages love this material because it sits at the seam between psychology and sociology, and the answer choices routinely mix a psychological stage theory with a sociological mechanism.
Social Mechanisms of Identity Formation
The Looking-Glass Self (Charles Horton Cooley)
Cooley argued that the self is fundamentally social in origin: we come to know ourselves through others. The process has three steps, and the MCAT tests the ordering:
- We imagine how we appear to another person.
- We imagine that person's judgment of that appearance.
- We develop a feeling about ourselves — pride, shame, confidence — based on that imagined judgment.
The decisive and most-tested feature is that step 2 is an imagined appraisal, not a measured one. A medical student who is privately certain her attending thinks she is incompetent will develop low professional self-esteem even if the attending actually rates her highly. Identity tracks the perceived appraisal, not the real one. This is why the looking-glass self is invoked in passages about stigma, impostor phenomenon, and internalized bias.
Role-Taking and the Generalized Other (George Herbert Mead)
Mead described self-development as the progressive ability to take the perspective of others:
| Stage | Approximate age | What the child can do | Illustration |
|---|---|---|---|
| Preparatory (imitation) | Under ~2 years | Copies behavior without understanding its meaning | Holding a toy stethoscope to a doll because a parent did |
| Play | ~2–6 years | Takes one significant other's role at a time | Playing "doctor," then separately playing "patient" |
| Game | ~7+ years | Coordinates multiple roles simultaneously | Playing a team sport, tracking what every position expects |
| Generalized other | Later childhood onward | Internalizes the attitudes of society as a whole | Behaving ethically because "people" expect it, not because a specific adult is watching |
Mead further split the self into the "I" — the spontaneous, impulsive, unsocialized actor — and the "Me" — the self as an object, reflecting internalized social expectations. A passage describing a physician suppressing an instinctive reaction to maintain professional composure is describing the "Me" regulating the "I."
Significant others are the specific individuals (parents, mentors) whose appraisals matter most; the generalized other is the abstract, aggregated viewpoint of the community. Distinguishing these two is a frequent discrete-question target.
Reference Groups
A reference group is any group an individual uses as a standard for self-evaluation. The critical exam point is that membership is not required. A first-generation premed who evaluates her progress against practicing physicians is using a non-membership reference group. Reference groups explain relative deprivation — dissatisfaction produced by comparison with a chosen standard rather than by absolute conditions — which is why a well-paid resident can feel deprived when comparing with attendings.
Stage Theories of Identity Development
The AAMC names four families of identity theory. You are expected to match a vignette to the theory and stage, not to memorize every detail.
| Theory | Organizing principle | What drives movement | Signature exam cue |
|---|---|---|---|
| Psychosexual (Freud) | Libidinal focus shifts across erogenous zones | Resolution of stage conflict; failure produces fixation | Oral, anal, phallic, latency, genital labels |
| Psychosocial (Erikson) | Eight lifespan crises, each a paired tension | Successful resolution yields a virtue | "Identity vs. role confusion" in an adolescent |
| Moral (Kohlberg) | Structure of moral reasoning | Increasing cognitive perspective-taking | A subject explains why an action is right |
| Gender identity | Development of a gendered self-concept | Cognitive schema formation and social learning | Child sorts behavior by gender labels |
Kohlberg's Levels in Detail
Kohlberg presented moral dilemmas (classically the Heinz dilemma) and scored the justification, never the verdict. Two subjects who both say Heinz should steal the drug can score at opposite ends.
- Level 1 — Preconventional (typically pre-adolescent): Morality is external. Stage 1, obedience and punishment: "He shouldn't steal because he'd go to jail." Stage 2, instrumental/self-interest: "He should steal because he needs his wife well."
- Level 2 — Conventional (most adolescents and adults): Morality is social. Stage 3, interpersonal accord ("good boy/nice girl"): "A good husband would steal." Stage 4, law and order: "Stealing is illegal and society needs laws."
- Level 3 — Postconventional (a minority of adults): Morality is principled. Stage 5, social contract: "Laws should be changed when they fail human welfare." Stage 6, universal ethical principles: "Human life outranks property in all circumstances."
The single most common Kohlberg trap: the answer choice that keys on the decision rather than the reasoning. Always locate the "because."
Gender Identity Development
Two mechanisms are named by the AAMC and are frequently contrasted:
- Gender schema theory (Bem): Children construct cognitive frameworks that organize the world into gendered categories, then assimilate new information into those schemas. The mechanism is cognitive.
- Social learning theory (Bandura applied to gender): Children acquire gendered behavior through modeling, imitation, and differential reinforcement from caregivers, peers, and media. The mechanism is observational learning.
Note the AAMC's separate insistence in Content Category 9B that sex is a biological classification while gender is a socially constructed set of roles and expectations — a distinction that recurs in identity questions.
Culture and Socialization as Identity Inputs
Identity formation is not culturally uniform. Individualistic cultures foster an independent self-construal in which identity is defined by internal attributes and personal achievement; collectivistic cultures foster an interdependent self-construal in which identity is defined by group membership, role obligation, and relational harmony. The same behavior — declining a promotion that would require relocating away from aging parents — reads as a failure of ambition under one construal and as a fulfillment of identity under the other.
Primary socialization (childhood acquisition of core language, norms, and values, largely through family) is distinguished from secondary socialization (learning the behavior appropriate to specific institutional settings, such as medical school) and from anticipatory socialization (rehearsing the norms of a role one intends to occupy — the premed who begins adopting clinical vocabulary and dress before matriculating).
Exam Traps to Avoid
- The looking-glass self is about perceived, not actual, appraisals. An answer choice describing accurate feedback is a distractor.
- Reference group membership is optional. Do not eliminate a reference-group answer because the subject does not belong to the group.
- Kohlberg scores reasoning. Two people with the same action can occupy different stages.
- Mead's "game" stage requires multiple simultaneous roles; taking one role at a time is the "play" stage.
A third-year medical student consistently believes her supervising physician views her as unprepared, and she reports declining confidence in her clinical abilities. End-of-rotation evaluations later reveal that the physician rated her among the strongest students on the service. Which concept best explains the student's diminished self-concept?
Two adolescents are presented with the Heinz dilemma. The first says Heinz should steal the drug "because his wife would be grateful and everyone would see him as a devoted husband." The second says Heinz should not steal the drug "because if everyone broke laws when it suited them, society could not function." According to Kohlberg, these two responses are best classified as:
A seven-year-old is playing soccer and simultaneously tracks what her coach, her teammates, and the opposing players each expect of her position. According to Mead, this capacity marks which stage of self-development?
A first-generation college student who has never met a physician socially evaluates her own academic progress against the standards she believes practicing physicians hold. Sociologically, practicing physicians function here as:
