Additionally, each schema consists of a set of expectations, and comprehension does not occur unless those expectations are met. Without a schema, Anderson (1984b) contends that learning can be slow and uncertain. Proponents of schema theory suggest that all knowledge is packaged into units (Anderson, 1984a). In addition to being packaged into units, schemata are organized knowledge as opposed to being simply lists of information (Schallert, 1982). They represent all the knowledge that is associated with a particular concept and not just essential definitional information. Schemata may be formed and used without conscious awareness.
