According to George Herbert Mead, children mimic or imitate others during the the first stage of learning.
Step-by-step explanation:
The first stage of learning is called as prepatory stage. While playing and interacting, they learn to take roles of others. The first stage of learning is at around the age of three years.
At this age, the children learn to interact with other people and thus learn to be like them. Playing various games like drama helps them to perform the roles of others like that of a teacher, or of a police man helps them to take on roles of other people and of those who they are not actually in real life.
