ABSTRACT
The problem of how we represent information about the world is central to cognitive psychology. The representation and operations upon it tell us how the person solves a problem, remembers a sentence, answers a question or makes a decision. An internal representation is a symbol structure, containing elements that are related to one another in some defined way, is constructed by the person in response to task demands and stored in memory for related purposes. The representation is constructed by processing stimuli and can be used to construct other representations, access descriptive information and retrieve properties of elements in response to inferential and other questions.
