The document discusses two theories about time perspective - Zimbardo's Time Perspective Theory and Markus and Nurius' Possible Selves Theory. Zimbardo's theory identifies five time perspectives (present hedonistic, present fatalistic, past positive, past negative, future oriented) and proposes that a healthy perspective balances all three time dimensions. The Possible Selves Theory holds that people's representations of their future selves motivate present actions and are shaped by social interactions and life goals. Both theories suggest that considering one's past, present, and future selves can help students determine their futures.
