Step-by-step explanation:
In Piagetian terms, the process that describes the radical reorganization of a schema regarding a certain group of people is accommodation. Accommodation is the adjustment of a schema by changing a scheme to accommodate new information that is different from what was already known. This process involves modifying existing cognitive structures to make room for new information or experiences.
For example, when an individual encounters new information or experiences that do not fit into their existing schema, they may need to accommodate their schema by creating a new category or modifying their existing categories.
