PIAGET’S VS. VYGOTSKY’S COGNITIVE DEVELOPMENT THEORY Name of Student: Name of Institution: Over the years many theories concerning the cognitive development of children have been developed by different psychologist like Piaget and Vygotsky. Jean Piaget came up with Cognitive Development Theory which focuses on the evolution of a person’s thoughts as from childhood to adulthood. Apart from that the study scrutinizes how a child develops a language which arises due to the relationship a kid has with the people and the surrounding environment. For one to understand the theory Piaget subdivided it into four parts which are the Sensorimotor Preoperational Concrete operational and Formal operations. At the Sensorimotor phase the infant way of communicating is through the use of senses and of age in theory thus making the study to be vague and speculative. In conclusion the two theories outline the development of language by infants. For instance Piaget gave a step by step breakdown from when a child uses senses and movements to when a child can express wrong words to sound general understanding and finally hypothetical theoretical and reasonable thinking. On the other hand Vygotsky uses Zone of Proximal Development where a child tries to organize words verbally by themselves and when assisted they perfect it. Reference Feldman R. S. (2016).
