Final answer:
Erikson's stage from 12-18 months to 3 years is known as 'autonomy versus shame and doubt,' critical for developing independence and self-concept in toddlers.
Step-by-step explanation:
Erikson's Stage: Autonomy versus Shame and Doubt
The name of Erikson's stage that falls between 12-18 months to 3 years is commonly referred to as the autonomy versus shame and doubt stage. In this early childhood period, a child learns to establish independence as they explore their world. The ability for toddlers to express their will and assert control, particularly during the 'me do it' stage, is crucial for developing a healthy sense of self-concept. A toddler, for instance, shows budding autonomy when they insist on choosing their clothes or dressing themselves, despite the appropriateness of the chosen attire.
Successful navigation through this stage results in a reinforced sense of autonomy, empowering the child with confidence and self-esteem. Conversely, if a toddler's emerging independence is stymied, they might experience feelings of shame and self-doubt, which can be detrimental to their developing self-concept. This stage plays a pivotal role in forming the foundation for later psychosocial development, as recognized by Erikson's theory, which emphasizes the social aspects of developing personality over time.
