Final answer:
In Erikson's stages of psychosocial development, a child learns self-control and feels more capable during the stage of Industry versus inferiority.
Step-by-step explanation:
In Erikson's stages of psychosocial development, the stage where a child learns self-control and begins to feel more capable is Industry versus inferiority.
During the elementary school stage (ages 7-11), children compare themselves to their peers to see how they measure up. They either develop a sense of pride and accomplishment in their schoolwork, sports, social activities, and family life, or they feel inferior and inadequate when they don't measure up.
To help children develop a sense of competence and belief in themselves, parents and teachers can provide opportunities for success, encourage effort and hard work, and provide constructive feedback and support.
