Step-by-step explanation:
According to Daniel Levinson's theory of adult development, the transitional stage before entering late adulthood is characterized by viewing oneself as both young and old. This stage is known as the late adult transition and occurs between the ages of 60 and 65. During this period, individuals may experience a range of emotions and thoughts as they reflect on their past and prepare for the next phase of life. It is important to note that Erik Erikson's theory of psychosocial development also captures the challenges and tasks individuals face in late adulthood.
