Vygotsky and Piaget Theory

Vygotsky and Piaget
Cognitive development can be described as the process in which a person constructs their thoughts for example, remembering things, problem solving and attention. In this essay I am going to evaluate the theories of Piaget and Vygotsky. I will look into the weaknesses and strengths of the theories with supporting evidence and also the similarities and the differences of the two theories.
Piaget believed that children develop through the interaction of innate capacities with environmental events (Gross 2005). He saw children as scientists and he also argued that cognitive development consists of four evident phases the first phase being the sensorimotor stage, the pre-operational, the concrete operational and the formal operation.
Piaget argued that cognition development in children developed through these four stages and that the thinking patterns always happened in a sequence with four key features. It also happened in the same order and no stage was skipped, each stage was an important change than the stage before it.
In the sensor motor stage from birth to two years, Piaget observed that childrens cognitive development was limited to natural involuntary response. Children build on these responses and develop complicated processes through physical interaction and experience (Gross 2005). At around seven months, the child learned that even if an object is out of sight the object still existed. This is what Piaget called object permanency In this stage the children will learn from their parents and those who care for them. At this stage children try to imitate what they hear from those around them.They also experiment with muscle movements sounds made by the mouth.
In the preoperational stage, which is from about two years to around seven years, children start to use mental images and language.
