Final answer:
A 1-year-old child is in the autonomy versus shame and doubt stage of Erikson's psychosocial development stages, focusing on developing a sense of independence.
Step-by-step explanation:
According to Erik Erikson's psychosocial development stages, a 1-year-old child is in the stage of autonomy versus shame and doubt. This stage typically spans the ages of 1-3 years and is marked by toddlers beginning to explore their world and asserting their independence. The core challenge of this stage is for the child to develop a sense of personal control over physical skills and a sense of independence. Success in this stage leads to feelings of autonomy, while failure results in feelings of shame and doubt. A 1-year-old is starting to learn that they can control their actions and act on their environment to get results, often exhibiting a 'me do it' attitude.
