Final answer:
Piaget called the incorporation of new objects into existing knowledge assimilation, while accommodation refers to the modification of schemas to accommodate new information.
Step-by-step explanation:
Piaget called the incorporation of new objects into existing knowledge assimilation. This process involves taking in new information or experiences and fitting them into pre-existing mental structures or schemas. However, when new information cannot be assimilated into existing schemas, Piaget referred to the process of accommodation. This is when individuals modify or create new schemas to accommodate the new information.
