Which theory was developed by Piaget?

Piaget is renowned for his work in developmental psychology, particularly his formulation of the Four Stage Theory of cognitive development. This theory outlines how children progress through distinct stages of cognitive growth at varying ages, emphasizing that they actively construct knowledge through their experiences. The stages are Sensorimotor, Preoperational, Concrete Operational, and Formal Operational, each representing a different way of thinking and understanding the world.

In contrast to this, the other theories mentioned focus on different aspects of psychology. The Two-factor theory relates to emotional responses and is credited to Schachter and Singer, while Learning theory encompasses various frameworks regarding how people acquire, process, and retain information, often associated with behavioral approaches. The Multiple intelligences theory, developed by Howard Gardner, proposes that intelligence is not a singular entity but rather a combination of various types of intelligences. Understanding Piaget's Four Stage Theory is crucial as it lays the groundwork for comprehending cognitive development and the nature of learning in children.
