Answer:
Social Learning.
Step-by-step explanation:
The father of this theory is called Albert Bandura and he proposed this theory in the year 1977.
This Social Development Theory (SDT) mainly asserts that social interaction has a vital role in the cognitive development process. With this concept, Vygotsky's theory opposes that of Jean Piaget's Cognitive Development Theory because Piaget explains that a person undergoes development first before he achieves learning, whereas Vygotsky argues that social learning comes first before development. Through the Social Development Theory, Vygotsky states that the cultural development of a child is firstly on the social level called inter psychological, and secondly on the individual or personal level called intra psychological.
