Piaget Theory

Piaget is considered as the leading, influential psychologist in concerns to cognitive development. He is best known for his theory of cognitive development or genetic epistemology. Epistemology is a branch in philosophy that investigates the origin, nature, methods, and limits of human knowledge. Piaget was not only curious about the nature of thought, but moreover, how genetics contributes to the process. Piaget suggested knowledge was the product of direct motor behavior.
He believed the only way to understand knowledge was to understand how it was acquired, therefore psychological and historical investigation was necessary.
Piaget strove to identify how children adapt to their environment. He noticed skills in a child that reinforced

The child’s development is determined by biological maturation and interaction with the environment. Although all children go through each stage in the same order, there are individual differences in the rate at which children progress through stages, and some may never go through the later steps. Each stage of development reflects an increasing sophistication of children’s thought. The first stage is the Sensorimotor stage. This stage ranges from birth to two years of age and can be broken down to six substages. The main objective of this stage is goal-directed behavior and object permanence. Goal-directed behavior combines several schemes and coordinates them to perform a single act to solve a problem. Object permanence is the realization to form a mental schema of an object that is not present but exists. The Preoperational Stage is the second stage and ranges from age two to seven. During this stage children increase their ability to think symbolically, as well as increase the use of concepts, centration, conservation,and intuitive thought emerge , and thinking remains egocentric. The third stage is the Concrete Operational change. Occurring between ages seven and twelve. Piaget characterized this stage as a major turning point in a child’s cognitive development because it applies operational thought. In this stage, children are
