Who Am I — and Who Told Me So?
Your identity is your sense of who you are: partly the private, personal traits you feel define you, and partly the social groups you belong to. A big piece of it — your sense of being a boy, a girl, both, or neither, and how you're 'meant' to behave because of it — is built from three ingredients working at once: your biology, the way your mind sorts the world into categories, and the people who reward, punish, and model behaviour around you.
Think of identity like a playlist. Some tracks were pre-loaded before you could choose (biology). Some you added because you learned the 'rules' of what fits your vibe and filtered out anything that clashed (your mental schema). And a lot got added because friends played them, you saw them liked, and you copied (social learning). The final playlist feels totally 'you' — but almost every track has a source you didn't invent alone.

What 'identity' means: personal and social
Identity is a person's sense of who they are — coherent, relatively stable, and used to guide decisions. Psychologists usually divide the self-concept into two strands. Personal identity is built from individual attributes: your traits, abilities, values and personal history — the things that make you feel like a unique individual. Social identity, by contrast, comes from the groups you belong to: your nationality, religion, gender, friendship group or team. Tajfel's social identity theory argues that we categorise ourselves into such groups and draw part of our self-esteem from them, which is why group membership can feel so personal.
Personal identity — 'I am patient, I value fairness, I love music': individual traits and values.
Social identity — 'I am British, a Muslim, a footballer': identity derived from group membership.
The two interact: how much a group matters to you becomes part of who you personally feel you are.
Gender sits at the intersection — it is both a deeply personal sense of self and a powerful social category.
Gender identity vs gender role — get the distinction right
Two terms are constantly confused, and mixing them up quietly damages an essay. Gender identity is a person's internal, private sense of their own gender — something felt. Gender role is the set of behaviours, attitudes and activities that a particular society treats as appropriate for that gender — something performed and culturally defined. A person's felt identity and the role their culture assigns can align or clash. Because roles are cultural, they vary across time and place, whereas the experience of having a gender identity appears near-universal even where its content differs.
Gender identity = the internal sense of being male, female, both or neither.
Gender role = the socially expected behaviours attached to a gender ('boys play rough', 'girls nurture').
Roles are culturally variable and historically changeable; identity is felt and comparatively stable.
In an essay, state which one you are discussing and keep your studies matched to it.
Explanation 1 — Biological: prenatal hormones organise gender
The biological explanation argues that gender-typed behaviour is influenced by biology, especially prenatal hormones. During foetal development, androgens (such as testosterone) are thought to 'organise' the developing brain in ways that later bias interests, play preferences and some aspects of gender-typed behaviour. This is not a claim that culture is irrelevant, but that there is a partly innate biological push that other factors then build on.
Supporting study — Berenbaum & Hines (1992). Aim: to test whether atypical prenatal hormone exposure affects gender-typed play. Procedure: they studied girls with congenital adrenal hyperplasia (CAH), a condition that exposes the foetus to unusually high androgen levels, and compared their toy choices with those of unaffected female relatives during a free-play period. Findings: CAH girls spent more time with toys typically preferred by boys (e.g. vehicles, construction) than the comparison girls. Use: this supports the biological explanation because a difference in prenatal hormones is linked to a difference in gender-typed behaviour, holding much of the family environment constant.
A second biological line — Imperato-McGinley (1974). In a Dominican community, some children with 5-alpha-reductase deficiency had ambiguous genitalia and were raised as girls, yet developed male genitalia at puberty and largely adopted a male gender role. This is used to argue that biology can, in some cases, override the gender of rearing — a serious challenge to purely social accounts.
Explanation 2 — Cognitive: gender-schema theory
The cognitive approach argues that children are active thinkers who build gender for themselves. Kohlberg proposed that understanding of gender develops in stages, culminating in gender constancy (knowing gender is fixed). Gender-schema theory (Bem, 1981; Martin & Halverson, 1981) goes further: as soon as a child can reliably label their own gender, they form a schema — an organised set of beliefs about what each gender does. That schema then acts as a filter: children pay more attention to, remember better, and prefer to imitate information that is consistent with their gender, while discounting inconsistent information. Crucially, this can happen earlier than full gender constancy.
Supporting study — Martin & Halverson (1983). Aim: to test whether children's gender schemas distort memory. Procedure: children were shown pictures of people performing activities that were either schema-consistent (e.g. a girl cooking) or schema-inconsistent (e.g. a boy cooking); a week later their memory of the pictures was tested. Findings: children more accurately remembered schema-consistent images, and systematically distorted inconsistent ones — for example 'correcting' a boy cooking to a girl cooking. Use: this supports gender-schema theory because it shows children actively reshape incoming information to fit an existing gender schema, exactly as the theory predicts — evidence of an internal cognitive process, not just imitation.
Explanation 3 — Social: social learning and reinforcement
The social learning explanation (Bandura) argues that gender roles are learned from the social environment through observation, imitation and reinforcement. Children observe models — especially same-sex models such as parents, peers and media figures — and are more likely to imitate behaviours they see rewarded (vicarious reinforcement). Adults also apply differential reinforcement, responding more warmly to gender-'appropriate' behaviour and discouraging the rest, so children learn which behaviours 'belong' to their gender.
Supporting study — Fagot (1978). Aim: to see whether parents reinforce gender-typed behaviour in toddlers. Procedure: naturalistic observation of parents interacting with their toddlers at home, recording reactions to different kinds of play. Findings: parents responded more positively when children engaged in gender-'appropriate' play and more negatively to gender-'inappropriate' play, and this differential reinforcement was present very early. Use: this supports the social learning explanation by showing the reinforcement mechanism operating in real family life, shaping gender roles before children could fully articulate them.
Social and cultural context, and the role of peers
None of the three explanations operates in a vacuum. Which behaviours count as gender-'appropriate', which models a child sees, and what gets reinforced are all set by the surrounding culture. Cross-cultural variation in gender roles is strong evidence that roles are not fixed by biology alone: what is 'masculine' or 'feminine' differs markedly across societies and eras. Peers matter enormously in childhood and adolescence — peer groups reward conformity to gender norms and sanction deviation, acting as a powerful reinforcement and modelling system beyond the family. This is exactly why a good essay resists single-factor explanations: culture and peers determine the inputs that the cognitive and social mechanisms then process.
Culture sets the content of gender roles — hence cross-cultural variation in what counts as 'appropriate'.
Peers reinforce and model gender norms, especially strongly in adolescence.
Media provides symbolic models, extending social learning far beyond the home.
These contextual factors are the inputs that biological predispositions, schemas and reinforcement all act upon.
Adolescence and identity formation (Erikson and Marcia, in brief)
Gender identity is consolidated within the broader adolescent task of forming an identity. Erikson framed adolescence as the psychosocial stage of 'identity vs role confusion', in which a coherent sense of self must be built or the person risks confusion about their place in the world. Marcia operationalised this into four statuses along two dimensions — exploration and commitment: diffusion (neither), foreclosure (commitment without exploration), moratorium (active exploration, not yet committed) and achievement (commitment after exploration). This framework is the developmental backdrop: adolescence is when many identity elements, gender among them, are actively questioned and settled.
Evaluation — thinking critically about the explanations and research
Reductionism vs interactionism — each single explanation is reductionist. Biology cannot explain cultural variation in roles; schema theory does not explain the prenatal hormone effects; social learning struggles with the Imperato-McGinley cases. The mature position is interaction.
Correlation, not causation — CAH studies are quasi-experimental: androgen exposure is not manipulated, and CAH girls may also be treated differently, so a purely causal biological reading is unsafe.
Cultural and temporal bias — much gender research is Western and dated; findings on 'boys' toys' partly reflect the norms of the sample's time and place, so generalisation is limited.
Methodological strengths and limits — Martin & Halverson's memory measure gives clean cognitive evidence but in an artificial task; Fagot's naturalistic observation is high in ecological validity but low in control and open to observer effects.
Direction of effect — differential reinforcement (Fagot) could reflect parents responding to pre-existing child differences rather than creating them, complicating the social-learning causal story.
Common mistakes examiners penalise
Confusing gender identity with gender role — identity is the internal felt sense; role is the socially expected behaviour. Blurring them makes studies mismatch the claim and quietly lowers Focus and Knowledge.
Describing studies instead of USING them — retelling a procedure earns Knowledge marks but not 'use of research' marks. Add a linking sentence: 'this supports/challenges the explanation because...'.
Using only one study — our marking engine caps Criterion C when a single study carries the whole essay. Include two well-explained studies tied to your two explanations.
Listing evaluation instead of developing it — a bullet list of 'strengths and limitations' is not critical thinking. Each point must be explained and linked back to the argument to credit Criterion D.
Single-factor over-claiming — asserting gender is 'purely biological' or 'purely learned' ignores the cross-cultural and case evidence; the defensible position is interaction.
Misstating gender-schema theory as imitation — schema theory is about active mental filtering of information, not simply copying a rewarded model; conflating it with social learning loses accuracy marks.
Answering a different question — 'discuss the formation and development of gender' is not the same as 'describe theories of identity'. Keep every paragraph pointed at formation/development of gender identity or role.
Worked examples
See the formulas applied — reveal one step at a time, like the exam.
Worked example 1 — Choosing and USING two studies for the SAME question. You must write on 'gender identity or role'. You have four studies (Berenbaum & Hines 1992, Martin & Halverson 1983, Fagot 1978, Imperato-McGinley 1974). For an essay contrasting the BIOLOGICAL and COGNITIVE explanations, which two studies do you make central, and how do you USE (not just describe) each?
- 1
Pick the two that map cleanly onto your two chosen explanations:
- Biological explanation → Berenbaum & Hines (1992).
- Cognitive/gender-schema explanation → Martin & Halverson (1983).
Worked example 2 — Turn one study into a critical point, not a summary. Take Fagot (1978). A weak answer writes three sentences summarising it. Show how to convert it into a developed critical-thinking point that would credit Criterion D.
- 1
Weak (description only): 'Fagot observed parents and toddlers at home and found parents reinforced gender-appropriate play more than inappropriate play, supporting social learning theory.' → This is fine for Criterion B/C but adds nothing to Criterion D.
Discuss the formation and development of gender identity or role. [22]
