Question

Quizplus · Accepted Answer

The statement "Boys can fight, but girls should play nice" is an example of an in-group-out-group gender schema, where boys are perceived as more aggressive and violent, and girls are expected to behave in a more submissive and peaceful manner. This reinforces traditional gender roles and stereotypes, creating a divide between the genders. The other options either do not relate to gender or involve other forms of stereotypes or taboo topics.
