ABSTRACT
Chomsky (1980) has argued that if we want to advance our understanding of the mind as a biological entity, we should study what it does easily and well. In particular, we should study those abilities that people acquire most naturally, with the least dependence on the environment. If that is to be the role of cognitive psychology, what becomes of instructional psychology? For if instructional psychology has a province, it is the province of things that have proved difficult to learn, that are believed to require substantial and purposely arranged contributions from the environment.
