Social interaction plays an important role in people's lives starting in early childhood, when infants interact with their caregivers and build the emotional attachment that forms the basis of relationships future. Through social interaction with others, children learn to communicate, play, and behave in particular situations. Berk (2009) provided an overview of the literature that focuses on early attachment and its importance. Knowing the influence of social interaction on the development of the child during the early years, the essay will develop the implication of social interaction on the development of cognition. Cognitive development, as claimed by Lee and Gupta (eds.), is the term that refers to the acquisition and development of knowledge and cognition, namely processes such as memory, language, solving problems and drawing.

The essay considers the context in which social relationships flourish, namely child-adult interaction and peer relationships. Through their early experiences with others, children develop their understanding of the world. Through simple activities carried out daily between children and caregivers, children are able to understand the meaning of new learning techniques and strategies, expand their existing knowledge and experience new things.

Although cognitive abilities do not fully develop in all children, social interactions encourage and stimulate progress..
