Rasch Measurement as a Communication System

Information communication may appear trivial: just "do it." But the development of telephone technology and the use of computers with large databases have motivated theoreticians to investigate how to construct efficient, noise-resistant communication systems.

Communication theory was originally conceived in terms of fixed mechanical and electrical systems. Social science systems, however, can change to improve or degrade communication. They can learn, forget, focus, and become distracted. Leydesdorff (1993) reformulates communication system theory for social science. He conceives communication systems in four "dimensions". The Table is extracted from his work. Equivalent features in Rasch analysis are appended.

Rasch methodology incorporates all the features which Leydesdorff models for a communication system. To omit any of these features is to risk, perhaps guarantee, miscommunication. He also discusses a fifth "dimension" of "evolution" or self-improvement. This is the challenge addressed by artificially intelligent communications systems. In Rasch methodology, the fifth dimension is the analyst's trained intelligence.
