Step-by-step explanation:
The basic idea and timeframe of Erik Erikson's fourth stage of psychosocial development is Industry vs. Inferiority, which occurs during the school age period of approximately 6-11 years. In this stage, children are navigating the complexities of learning and social interactions in a school setting. Success in this stage is characterized by a sense of competence and achievement, while failure may result in feelings of inferiority and lack of self-worth. The ability to work with others, learning new skills, and achieving goals contribute to the child's sense of industry. If children struggle and do not learn how to cope with challenges or do not receive support from caregivers and teachers, they may develop a sense of inferiority, doubting their abilities and lacking confidence in their potential.
