Final answer:
Developmental tasks are skills and competencies that lead to mastery at different life stages, according to Erik Erikson's psychosocial theory. Each stage has specific tasks that contribute to a sense of competence and a healthy personality. These tasks encompass physical, cognitive, and psychosocial domains of development.
Therefore correct option is B
Step-by-step explanation:
The best definition of developmental tasks is skills and competencies that contribute to increased mastery. According to Erik Erikson's psychosocial theory of development, these tasks are a series of challenges that individuals are expected to master as they progress through different stages of life. Each stage presents a unique conflict or task that, when resolved, contributes to the individual's sense of competence and leads to a healthy personality. Failure to master these tasks can result in feelings of inadequacy.
Erikson's theory delineates eight stages of development, each with its psychosocial tasks, such as the adolescent stage which focuses on the task of identity versus role confusion, where adolescents question "Who am I?" and "Who do I want to be?" Developmental psychology considers this aspect of growth within the wider scope of physical, cognitive, and psychosocial development, as well as how our diverse contexts can uniquely influence our development.
