An empirically-based theory is proposed that relates media's most essential modes of presentation--their symbol systems--to modes of cognitive representation and to the acquisition of knowledge. This book draws upon scholarship in such areas as the study of symbol systems, cognition, cognitive development, psycholinguistics, and mass…

The class of media characteristics, which is generic to them and which may be of potentially great relevance to learning, is the way in which media select, highlight, structure, and present information, i.e., their "languages" or symbol systems.

The failure of research on media to deal with media's symbol systems is discussed. Nature of symbol systems is described and related to cognition and learning. Symbolic elements used by media can facilitate the cultivation of mental skills in interaction with individual differences and depth of processing. (Author/RD)
