Jean Piaget was the second most referenced psychologist of the 20th century whose work was dedicated to mapping out the stages of human development that is now known as the Piaget Theory of Cognitive Development. Piaget differentiated four developmental stages that humans pass through: sensorimotor, preoperational, concrete operational and formal operational. These stages of Piaget’s Theory of Cognitive Development take place at different ages with Sensorimotor occurring between 0-2, Preoperation (or preop) between 3-7, Concrete Operational (or conop) between 7-11) and Formal Operational (formop) being found in children over 11. As well as the work of Jean Piaget we touch a little on Post-Piagetian stages such as Michael Commons’ Model of Hierarchical Development (MHC) as well as Ken Wilber who we will be looking at in more depth in the next episode. These are the stages of the Piaget cognitive development theory; we all pass through these stages on our way to adulthood and Piaget’s theories have been tested across cultures across the world. While it has faded from academic prominence it is one of the shaping theories of the field of psychology. _________________ ⭐ Support the channel (thank you!) ▶ Patreon: https://patreon.com/thelivingphilosophy ▶ Ko-fi: https://ko-fi.com/thelivingphilosophy________________?
