Piaget's Cognitive Development Stages
The theory of Cognitive Development Stages presented by Piaget outlines the different, successive steps of cognitive growth in children. This conception was made by a noted Swiss psychologist, Jean Piaget. These four phasessensorimotor, preoperational, concrete operational, and formal operationaldemonstrate how, from the simple level of sensory perception, children's brains evolves to the complex ability of abstract reasoning, active learning through the interaction with the environment thus gaining the importance of emphasis.
Piaget's Cognitive Development comprises four stages, which include the following: 1) Sensorimotor Stage (from birth to 2 years), when infants and toddlers learn by interacting with their environment through their senses and through motor actions; 2) Preoperational Stage (2 to 7 years), which symbolizes the distinctive feature of symbolic thought and egocentrism; 3) Concrete Operational Stage (7 to 11 years), kids are able now to carry out logical operations about concrete situations; 4) Formal Operational Stage (12 years and up) where there is reasoning based on concepts that do not have real world equivalents and deals with hypothetical situations.
The Sensorimotor Period is the most important one as it sets the base for everything that comes after it in terms of cognitive development. In this period, infants grow into the object permanence stage which is the first step to the problem-solving and memory skills that will come later in life. A toy that is temporarily hidden is the best way for a child to demonstrate an insight into the object permanence principle.
The Preoperational Stage is marked much more by imaginary play and the use of language, and, on the other hand, egocentrism and the incapability to understand conservation—principles that hold irrespective of the change in appearance. A good example of this can be a child who thinks that a cubic meter glass which is thinner and taller looks better than a well-shaped cubical glass is wider and shorter, which is making similar energy concepts harder for the child to think about.
The Concrete Operational Stage is characterized by the logic and mental operations concerning concrete situations, such as the conceptualization of the concept of conservation. On the other hand, the Formal Operational Stage is a stage for allowing the reasoning that is not bound by physical reality, problem-solving, and hypothetical thinking. For instance, a child in the Concrete Operational Stage might use visible objects to solve math problems, whereas a Formal Operational teenager could tackle difficult algebra equations and think about abstract subjects like justice or morality.
