What makes schema a cognitive concept rather than a behaviourist one?
The schema is a cognitive concept because of its dependence on the memory processes, the mental process of categorizing
and the retrieval processes of the brain. With each encounter, the we often think back to if it is something we have previously experience thus knowing how to function or we seek to observe and understand new experiences to later return to them when a similar situation arises.
