Piaget




 * Cognitive theory is concerned with the development of a person's thought processes. It also looks at how these thought processes influence how we understand and interact with the world.**

__Sensorimotor (Birth-2yrs) - __ Infants mainly make use of sense and motor capabilities to experience the environment. “Thinking only by doing” assists infants in gaining physical knowledge. __ Preoperational Stage (2-7 years __) - Children start to use symbols such as language to represent objects. They learn from concrete evidence. At this stage they are unaware of another persons’ perspective, and exhibit egocentric thought and language. The limitation of this stage is that it lacks the concept of conservation, likely to center on only one dimension.  __ Concrete operational stage (7-11 years) __ - At this stage, the child begins to think logically and learns from personal experience. This stage allows children to classify several classes into a bigger group or to combine a number of classes in any order. It also allows children to order objects in terms of more than one dimension. __

Formal operational stage (11 +) - __ At this stage students have the ability to consider many possibilities for a given condition. They are able to deal with propositions that explain concrete facts. Teens increase their ability to think abstractly, in which they can solve complex and hypothetical problems, involving abstract operations.
