Piaget and Vygotsky: The Psychology of Cognitive Development

This article deals with cognitive development psychology. Cognitive development can be explained by childhood acquisitions from adulthood to adulthood, acquisition of thought processes such as problem solving and decision making, and constructive and gradual change (Smith, PK, Cowie, H & Blades, M. 2003). Jean Piaget (1926) and Lev Vygotksy (1978) are the main pioneers in this field and their research is the basis of cognitive psychology research. The common understanding of both depends on the perspective of child's cognitive development through the stages, but their way of identifying these stages is quite different (Smith PK et al.

According to Meece (2002), Piaget and Vygotsky are two famous scholars of cognitive development theory. Piaget is biology, psychology and philosopher, Vygotsky first got a law degree, then a psychology degree. Despite having two different backgrounds, both scholars use a constructivist approach to cognitive development studies. And it believes that they "must build an understanding of the world of their own life". I have discussed this idea for many years. Piaget and Vygotsky are two famous scholars in the field of cognitive development. Their theory of cognitive development has an important influence on the development of educational theory.

Comparing and contrasting Piaget and Vygotsky's views on cognitive development problems. Piaget believes that development precedes learning, and Vygotsky proposes that formal school learning pushes development up to a new level. Both theorists highlight the importance of the game in the development of early childhood cognition. But Piaget believes that pretending to be a game is a separate process, Vygotsky thinks it is social and personal. Theorists also agree that language plays a role in logical thinking and share similar views on the role of internalized languages ​​in thought. They believe there is a difference between the plan of action and the role of an externalized language in normative thinking - Piaget believes this is a weak point of preoperative children's perception.

Comparison of Piaget 's basic principle and Vigotsky' s cognitive development. Piaget explains cognitive development from a biological point of view and explains what intellect is derived from the ability of human adaptation and organization. Piaget clarify that believe that children absorb ideas into groups or "plans" that contain information that does not fit the existing plan or absorbs new information. This contrasts with Vygotsky's cognitive development theory that children convert and internalize information about the world through language. For Vygotsky, social interaction is the main driving force for development. When a child listens to the language she imitates it until it becomes internalized and appears as an internal language in the head.
