Final answer:
Erikson's psychosocial theory suggests that new opportunities for personal growth exist in later adulthood, making the statement true.
Step-by-step explanation:
The psychosocial theory, proposed by Erik Erikson, posits that there are opportunities for growth and personal development throughout the entire lifespan, including later adulthood. In this theory, each stage of life comes with its own conflicts and tasks that must be resolved or mastered. Specifically, in late adulthood, the task is to achieve a sense of integrity rather than despair, reflecting on life with satisfaction and accepting past decisions, which in turn can lead to new opportunities for growth, such as learning new skills or engaging in new activities. Therefore, the statement 'Psychosocial theory assumes that there are new opportunities for growth in later adulthood' is True.
