Final answer:
The early adulthood stage in Erikson's theory of psychosocial development is defined as approximately 20 to the early 40s and is characterized by the challenge of intimacy versus isolation. Therefore, the statement that early adulthood spans from 18 to 40 years is True.
Step-by-step explanation:
Erik Erikson's stages of psychosocial development assign different challenges to various stages in a person's life. When it comes to early adulthood, which Erikson defines as ranging approximately from 20 to the early 40s, the primary psychosocial challenge is intimacy versus isolation. This is a time when individuals focus on forming intimate relationships, advancing in careers, and potentially starting families.
In late adulthood, which begins in the mid-60s and lasts until the end of life, the focus shifts to the challenge of integrity versus despair. At this stage, individuals reflect on their lives and may either feel satisfaction and integrity from their accomplishments or despair and regret if they feel their lives have not been fulfilling.
True or False: When the student asks if the early adulthood stage spans from 18 to 40 years, the answer is True based on Erikson's definitions. This period is characterized by significant life milestones such as finishing education, building a career, and establishing long-lasting relationships.
