ARTICLE3: JEAN PIAGET'S COGNITIVE DEVELOPMENT


Jean Piaget's research on cognitive development involved observing small number of individuals as they responded to cognitive tasks that he designed. These task known as " Piagetian Task ". He called his general theoretical framework " genetic epistemology " because he was interested in how knowledge developed in human organisms.

There are four stages of Piaget's Cognitive Development. First stage, is the sensori-motor, which corresponds from birth to infancy. The term sensori-motor focuses on the prominence of the sense and muscle movement through which the infant comes to learn about himself and the world.

The second stage is the pre-operational stage. It covers from about two to seven years old, corresponding to the preschool years. At this stage, children can now make mental representations and is able to pretend, because the intelligence is intuitive in nature. They are also closer to the use of symbols.

The third stage is characterized by the ability of the child to think logically but only in terms of concrete objects, and this is called the concrete-operational stage. It covers between 8-11 years or the elementary school years.

The fourth and final stage of Piaget's Cognitive theory, is the formal operational stage. This stage covers the ages between 12 and 15 years. The thinking ability of a child at this stage, is becoming more logical. They can now solve abstract problems and can hypothesize.
