Fifteen-year-old Mel thinks that she might be a lesbian, but she isn't really sure yet. She is exploring gay and lesbian literature and has read some of the scientific literature on homosexuality. By contrast, 16-year-old Nancy self-identifies as a lesbian and sometimes participates in social events for gay and lesbian youth at a local community center. In Marcia's terms, Mel is in the stage of identity development, while Nancy reflects the stage.
