The idea
Gender incongruence is the mismatch between biological sex and experienced gender identity, distinct from gender dysphoria. Biological explanations focus on atypical brain development, such as variations in the bed nucleus of the stria terminalis (BSTc), or genetic factors indicated by twin studies showing higher concordance for monozygotic twins. However, sexual dimorphism in the BSTc emerges in adulthood, challenging claims of prenatal development. Social and cultural explanations emphasise environmental influences. Psychoanalytic theories suggest incongruence arises from extreme separation anxiety, while learning theories point to the reinforcement of cross-gender behaviours. Cultural variations highlight the role of societal norms.
What earns the marks
- Define gender incongruence as the mismatch between assigned biological sex and experienced gender identity, distinguishing it from gender dysphoria.
- Explain biological factors, including brain structure anomalies (like the BSTc) and genetic vulnerability supported by twin studies.
- Describe social and cultural explanations, such as operant conditioning of cross-gender behaviour or psychoanalytic perspectives on extreme separation anxiety.
- Evaluate the explanations by discussing the reductionism of biological theories versus the difficulty of empirically testing social and psychoanalytic theories.
Common mistakes and how to put them right
Conflating gender incongruence with gender dysphoria.
Put it right: Define gender incongruence as the mismatch between sex and gender identity, and gender dysphoria as the psychological distress that may result from this mismatch.
Claiming biological explanations are definitive.
Put it right: Acknowledge that brain differences like the BSTc could be an effect of hormone therapy or emerge in adulthood, rather than being the prenatal cause of incongruence.
Ignoring the interactionist approach.
Put it right: Avoid presenting biological and social explanations as mutually exclusive, as both likely contribute to gender incongruence.
Exam tips
- Prepare to discuss the nature-nurture debate, using biological explanations for nature and social/cultural explanations for nurture.
- Use specific anatomical terms like the bed nucleus of the stria terminalis (BSTc) when detailing biological explanations to access higher mark bands.
- Critique the methodology of twin studies in this area, noting that small sample sizes limit the generalisability of genetic explanations.
