Stage One: Sensorimotor Stage
The sensorimotor stage is the initial phase of cognitive development in children. It commences at birth and continues until they reach approximately two years of age. During this stage, infants rely on movement and sensation to understand the world around them. Their primary means of processing information include grasping, sucking, looking, and listening. They gradually become aware that their actions have the power to bring about changes in their environment. Moreover, they acquire the concept of object permanence, understanding that objects continue to exist even when they are no longer visible.
Stage Two: Preoperational Stage
The preoperational stage, which occurs between the ages of two and seven, is the second stage in Piaget’s theory of cognitive development. During this stage, children further develop their language skills and begin to think in a more symbolic manner. They learn to use pictures and words to represent objects and ideas, moving beyond a literal understanding. However, due to their concrete thinking, they may struggle with abstract concepts and symbolism. Additionally, children in this stage tend to be egocentric, meaning they have difficulty seeing things from other perspectives.
