Abstract

The links which connect the nature of the medium to the methods of access and to the objects of knowledge, relationships between form and content, are a broad continuum whose interlinked facts require a transdisciplinary study.Nowadays, attempts to discern these links seem to concern two central groups of correlations, which have been analysed from the perspective of different disciplines.In the foreground of correlations we find the relationship between the material characteristics of the mediums and the methods of access to their contents; in this field of cultural technologies, the history of verbal language is punctuated first by the ‘invention’ of writing and its different systems, then by a series of transformations of manuscripts and the printed word, and finally by electronic communication. In the study of this first relationship, the history, psychology and physiology of reading establish a relationship between several parameters: on the one hand, the system of signs and spaces in the organization of the written code, and on the other hand, the methods of appropriation of this code by the reader (both reading aloud and silent reading), linear progression or freedom of selection of the contents, degree of speed, amount of information” habits of memorization, etc.
