Self-Concept, Self-Identity, and Social Identity

Priority labels: Must know = cold; Know the logic = mechanism not names; Passage-level = recognize, don't memorize; Optional = skippable.

What Is Self-Concept?

Must know

Your self-concept is the entire cognitive picture you hold of who you are — beliefs about your personality, roles, abilities, group memberships, and values. It answers "Who am I?" and is descriptive, not evaluative. It is shaped continuously by experience and others' responses.

Self-identity is the subjective sense of continuity and ownership over that portrait — the feeling that you are the same "you" across time. Where self-concept is the content ("I am an athlete"), self-identity is the sense that those contents cohere into one ongoing self.

Self-concept is organized into self-schemas (Hazel Markus) — domain-specific self-beliefs ("I am athletic") that guide how we process self-relevant information. Markus also described possible selves (hoped-for, expected, feared) that act as future-oriented motivators.

Two classic frameworks describe how the social world constructs self-concept:

The Looking-Glass Self

Must know

Charles Cooley: self-concept is built by imagining how others perceive us and internalizing that imagined appraisal. Three steps: (1) imagine how we appear to others, (2) imagine their judgment of it, (3) incorporate that judgment. Like a mirror, others reflect a version of us back. This is why a child raised with constant criticism may internalize a negative self-concept.

The "I" and the "Me" — Symbolic Interactionism

Must know

George Herbert Mead: the self has two parts — the "I" (spontaneous, impulsive, acting self/subject) and the "Me" (internalized social self, the self as object seen from outside). Identity emerges from the ongoing dialogue between them; the "Me" carries society's expectations, the "I" responds with agency. This framework — symbolic interactionism — holds that meaning, including the self, is created through social interaction and shared symbols (language, gestures, roles).

Dramaturgy and Self-Presentation — Goffman

Passage-level

Erving Goffman's dramaturgical approach: social life is theater, and we engage in impression management — controlling how others perceive us. Front stage = performing for an audience (a physician projecting competence); back stage = stepping out of role (venting in the break room). Related self-presentation motives: self-verification (confirming existing self-views) and self-enhancement (seeking to be seen positively).

Quick check: A medical student is rehearsing how to introduce herself to patients, picturing how the patient will perceive her and feeling self-conscious. Which framework best explains this?

Answer: The looking-glass self (Cooley) — she imagines an other's appraisal and uses it to shape her sense of self in that role.

Self-Esteem, Self-Efficacy, and Locus of Control

These three constructs sound similar but operate very differently — keeping them distinct is a major test skill.

Self-Esteem

Must know

Self-esteem is the evaluative component of self-concept — your overall sense of your own worth ("I am a person of value"). It can be trait (stable) or state (momentary). The Rosenberg Self-Esteem Scale (10-item) is the classic measure.

Consequences: high self-esteem links to resilience; low self-esteem is a risk factor for depression and anxiety. People protect self-esteem via self-serving bias — attributing successes to internal factors and failures to external ones. Self-esteem is also somewhat domain-specific (high academic, low athletic), with global self-esteem an average weighted by how much each domain matters to you.

Quick check: A student fails an exam and says "The professor wrote a terrible test," then aces the next and says "I'm just naturally smart." Which mechanism protects her self-esteem?

Answer: Self-serving bias — failure attributed externally, success internally.

Self-Efficacy

Must know

Self-efficacy (Albert Bandura, social cognitive theory) is your confidence in your ability to perform a specific task or behavior. Unlike global self-esteem, it is situational — high for surgery, low for public speaking.

Know the logic

Bandura's four sources: mastery experiences (succeeding yourself — most powerful), vicarious experiences (watching a similar other succeed), social persuasion (credible encouragement), and physiological/emotional states (interpreting arousal as readiness vs. inability). Clinically, patients with high self-efficacy for adherence actually adhere more — self-efficacy is the mechanism behind many behavioral interventions.

Quick check: A first-generation college student watched her older sister become a physician and now believes she too can finish medical school. Which source of self-efficacy is this?

Answer: Vicarious experience — modeling her belief on an observed similar other.

Locus of Control

Must know

Locus of control (Julian Rotter): where a person believes control over outcomes is located.

• Internal: "My outcomes come from my own efforts and choices."
• External: "My outcomes are controlled by luck, fate, powerful others, or circumstances."

It is a continuum, varying by domain. Internal locus predicts more motivation, persistence, and healthier behaviors; external locus links to learned helplessness — giving up when no connection is perceived between actions and outcomes.

Passage-level

Socioeconomic disadvantage is associated with more external locus — not from being "less driven" but because external constraints genuinely exert greater control. The MCAT tests socially aware interpretation of such findings.

Quick check: Two patients are told diet changes can lower their blood pressure. A: "Great — this is in my hands." B: "I doubt it'll matter; bad genes and my stressful boss." Which locus orientation describes each?

Answer: A → internal; B → external.

Social Comparison and Reference Groups

Must know

Leon Festinger's social comparison theory: especially when objective standards are unavailable, people evaluate themselves by comparing to others. Upward comparison (to someone better off) can motivate but may lower self-esteem; downward comparison (to someone worse off) protects self-esteem. The standard we compare against is a reference group — and we need not belong to it (an aspiring physician may already use the profession as a reference group).

Quick check: A patient compares herself to others on the ward who are far sicker and feels reassured about her prognosis. Which type of comparison is this?

Answer: Downward social comparison (Festinger).

Identity Development

Self-concept is actively constructed over time. The frameworks below describe how a coherent identity emerges and how mismatches between "selves" drive emotion.

Erikson's Identity vs. Role Confusion

Must know

Erik Erikson described psychosocial development as lifespan stages, each posing a crisis. The stage defining self-identity is Identity vs. Role Confusion, in adolescence: resolving it yields a coherent, committed sense of self; failure leaves role confusion — difficulty committing to values or a vocation. (The full eight-stage model and Marcia's four identity statuses are developed in the Formation of Identity guide.)

Self-Discrepancy Theory

Must know

E. Tory Higgins: we maintain multiple selves —

• Actual self — how you actually are.
• Ideal self — who you aspire to be (hopes, wishes).
• Ought self — who you feel you should be (duties, obligations).

Discrepancies generate specific emotions: Actual ≠ Ideal → dejection/sadness; Actual ≠ Ought → anxiety/guilt. Clinically, depressed patients often show large actual–ideal gaps; anxious patients feel they fail "ought" standards.

Quick check: A student feels intense guilt that he hasn't volunteered enough for his religious community, though his grades are strong. Which self-discrepancy explains his distress?

Answer: Actual vs. ought self — failing obligations generates guilt.

Social Identity Theory

Must know

A huge portion of self-concept comes from the groups you belong to. Henri Tajfel and John Turner developed Social Identity Theory (SIT) to explain this.

Core Claims of Social Identity Theory

Must know

Your social identity is the part of self-concept derived from group memberships (race, teams, nation, profession, religion). Three processes underlie it:

1. Social categorization — sorting people (and ourselves) into groups; the first step toward bias.
2. Social identification — adopting the identity of our groups and aligning with their norms.
3. Social comparison — favorably comparing in-group to out-group, boosting collective (and personal) self-esteem; the basis of in-group favoritism.

Know the logic

Minimal group paradigm — Tajfel showed in-group favoritism appears even with arbitrary, meaningless group assignments. Categorization alone is sufficient to generate group loyalty and out-group bias.

In-Group, Out-Group, and Stereotype Threat

Must know

An in-group is one you belong to and identify with; an out-group is perceived as other. In-group favoritism produces out-group derogation, feeding prejudice and discrimination — directly relevant to health disparities.

Stereotype threat (Claude Steele): being at risk of confirming a negative stereotype about your group impairs performance — not because the stereotype is true, but because awareness of it consumes cognitive resources and generates anxiety. Classic demonstration: Black students underperformed when a test was framed as measuring intellectual ability, but performed equally well when framed neutrally. Highly testable around achievement gaps and health outcomes.

Quick check: A woman taking a hard math test is told "women tend to struggle with advanced math" and scores lower than equally-able male peers. Which phenomenon is at work?

Answer: Stereotype threat (Steele).

Types of Identities

Must know

Identity is multidimensional — no person has just one. Which identity is foregrounded is context-dependent: identities form a salience hierarchy (the "physician" identity most salient in clinic, "parent" most salient at home).

Race and Ethnicity

Must know

Race is a socially constructed category based on perceived physical traits — not biologically discrete (more genetic variation within racial groups than between them), yet socially powerful in shaping resources, discrimination, and health. Ethnicity is shared cultural heritage (language, traditions, national origin), independent of how one is racially categorized by others.

Optional

Racial identity development models (e.g., William Cross for Black identity: pre-encounter → encounter → internalization) frame racial identity as actively constructed, not assigned.

Gender

Must know

Distinguish precisely:

• Biological sex — assigned at birth from chromosomes, hormones, anatomy (male, female, intersex).
• Gender identity — internal sense of one's own gender (psychological, not anatomical).
• Gender expression — outward presentation (clothing, behavior, appearance).
• Gender roles — societal expectations for a given gender.

These four are independent of each other and of sexual orientation. Gender socialization — learning a culture's gender norms — begins at birth via family, peers, media, and institutions.

Age and Generational Identity

Passage-level

Age is biological and social. Ageism = prejudice/discrimination by age, usually targeting older adults. Cohort effects (shared experiences of an age group) shape values and health behaviors across the lifespan.

Sexual Orientation

Must know

Sexual orientation is the enduring pattern of emotional/romantic/sexual attraction — distinct from biological sex, gender identity, and expression, and existing on a continuum (the Kinsey Scale, 0–6, was an early attempt to capture it). MCAT passages often invoke minority stress theory — chronic stress from stigma, discrimination, and concealment drives health disparities (not any pathology of orientation itself).

Social Class

Passage-level

Social class / SES is set by income, wealth, occupational prestige, and education — both an economic position and a social identity. It shapes health behaviors, access to care, and outcomes; health disparities tied to class and race are frequently tested.

Intersectionality

Must know

Intersectionality (Kimberlé Crenshaw): multiple identity categories (race, gender, class, etc.) overlap to create unique, compounded experiences of privilege and oppression. A Black woman's experience is not "Black + woman" but a distinct social position. On the MCAT, this explains why disaggregating health data by multiple identities is necessary, and why single-dimension research misses patterns.

Quick check: A researcher finds average income for "women" is lower than for "men," but the gap is far worse for women of color and varies by class. Which framework guides this analysis?

Answer: Intersectionality (Crenshaw) — gender, race, and class interact to produce distinct positions.

Common Confusions & Tricks

Self-esteem vs. self-efficacy: Self-esteem is global (overall worth); self-efficacy is specific (confidence in one task). High self-esteem doesn't guarantee high self-efficacy anywhere. Domain-specific confidence / "I can perform this behavior" → self-efficacy (Bandura); overall sense of worth → self-esteem.

Locus of control vs. self-efficacy: Locus of control is about causation (who controls outcomes — me or external forces?); self-efficacy is about capability (can I do this task?). You can have high self-efficacy but external locus (I run the experiment well, but publication depends on journal politics).

Gender identity ≠ sexual orientation: Entirely independent. Gender identity = "who I am"; sexual orientation = "who I am attracted to."

Race vs. ethnicity: Race = socially constructed around perceived physical traits; ethnicity = shared cultural heritage. One may be racially categorized one way and identify with a different ethnicity.

Ideal vs. ought discrepancy (Higgins): Ideal → dejection/depression; Ought → anxiety/guilt. Mnemonic: Ideal → Implodes into sadness; Ought → Overburden of anxiety.

Stereotype threat ≠ stereotype is true: The impairment comes from awareness and fear of confirming the stereotype — a situational effect, not evidence of ability differences.

Cooley vs. Mead: Cooley = looking-glass self (imagining others' appraisals; the mirror metaphor). Mead = "I" and "Me," symbolic interactionism (identity from social interaction; the internal dialogue).
