Final answer:
Gender dysphoria is explained by the social learning theory (SLT), which suggests that individuals learn gender roles through observation and imitation.
Step-by-step explanation:
Gender dysphoria is a diagnostic category in the DSM-5 that describes individuals who do not identify as the gender associated with their biological sex. The social learning theory (SLT) can provide an explanation for gender dysphoria by suggesting that individuals learn gender roles and expectations through observation and imitation. According to SLT, individuals with gender dysphoria may have observed and identified more strongly with the gender roles of the opposite sex, leading to a higher level of discomfort with their assigned gender.
