Final answer:
Daniel Levinson described the period between age 40 and 45 as the midlife transition, a stage of reassessment and potential change that is consistent with the concept of generativity versus stagnation in Erikson's theory of psychosocial development. Option b. is correct.
Step-by-step explanation:
According to Daniel Levinson, between age 40 and 45, people move into a period called the b. Midlife transition. This period is part of middle adulthood, which usually lasts from the mid-30s to the mid-60s. During this midlife transition, individuals often reassess their life's achievements and contemplate changes in their life paths. They may focus on personal and professional growth, seek out new challenges, or engage in mentoring and developing others, which aligns with Erikson's concept of generativity versus stagnation.
This stage contrasts with the later period of late adulthood, where the psychological challenge is integrity versus despair. While the term 'midlife crisis' is often used colloquially, Levinson's theory specifically references a transition rather than a crisis. It's a time for reflection and potential reorientation, rather than an inevitable crisis point.
