Formats and Language of Knowledge: Models of Links for Learning Processes

In this paper we will examine if communicability is a structural constraint on our information representation, acquisition and processing. In particular, first of all we will examine the description of the different formats of knowledge: declarative, propositional, procedural knowledge, narrative thinking, mental imagery. We will then consider the possible links between language and thought and especially between formats of knowledge, languages and the multimodal message. As a matter of fact the relationship between language and thought can be described by two events: a referential and a communicative one. Through the referential event the information we experience (perceptual, psychological, cultural) is organized into knowledge (knowledge of words, images, procedures); the communicative event requires the declension into languages through a medium, generating the multimodal message.
