Final answer:
In Erik Erikson's theory, preschool children develop independence and self-worth by taking initiative in tasks; successful initiative leads to confidence and purpose, while stifling initiative can cause guilt and negatively impact self-concept.
Step-by-step explanation:
The significance of a child's motivation to accomplish tasks in terms of independence and self-worth, according to Erik Erikson's preschooler stage, is highly influential in their development. During this stage, children explore initiative versus guilt as they initiate activities and assert control through social interactions and play. Success in planning and achieving goals builds their self-confidence and fosters a sense of purpose. Conversely, if a child's initiative is stifled, often through over-controlling parenting, it may lead to feelings of guilt and affect their self-concept negatively.
