Task: Question Answering
Input (English): Passage: Weinreich's identity variant similarly includes the categories of identity diffusion, foreclosure and crisis, but with a somewhat different emphasis. Here, with respect to identity diffusion for example, an optimal level is interpreted as the norm, as it is unrealistic to expect an individual to resolve all their conflicted identifications with others; therefore we should be alert to individuals with levels which are much higher or lower than the norm – highly diffused individuals are classified as diffused, and those with low levels as foreclosed or defensive. (Weinreich & Saunderson, 2003, pp 65–67; 105-106). Weinreich applies the identity variant in a framework which also allows for the transition from one to another by way of biographical experiences and resolution of conflicted identifications situated in various contexts – for example, an adolescent going through family break-up may be in one state, whereas later in a stable marriage with a secure professional role may be in another. Hence, though there is continuity, there is also development and change. (Weinreich & Saunderson, 2003, pp 22–23). Question: Identity diffusion, foreclosure, and crisis are categories of what?
Output (English): Weinreich's identity variant
