Final answer:
Jean Piaget recognized three factors necessary for developmental processes: assimilation, accommodation, and equilibrium.
Step-by-step explanation:
Jean Piaget recognized three factors that are necessary for developmental processes: assimilation, accommodation, and equilibrium.
Assimilation is the process of incorporating new information into existing cognitive structures or mental schemas. For example, a child who encounters a cat for the first time may assimilate it into their existing schema for dogs.
Accommodation is the process of modifying existing cognitive structures or mental schemas in response to new information. Continuing with the previous example, if the child realizes that cats are different from dogs, they will need to accommodate their schema for dogs to include separate information about cats.
Equilibrium refers to the balance between assimilation and accommodation. Piaget believed that individuals seek harmony and balance between their existing schema and new information, and equilibrium is achieved when assimilation and accommodation are in equilibrium.
