Media-didactics have recently become more firmly grounded on cognitive theory, with an increasing concern for the internal processes of knowledge representation and acquisition. With this cognitive aspect in mind, an international group of researchers held a meeting in Tübingen, Federal Republic of Germany, to present and discuss the theoretical approaches to and empirical investigations of knowledge acquisition from text and pictures.
This volume contains the revised contributions resulting from that meeting.

Introduction Texts and pictures can be regarded as media because they visualize parts of reality which are not immediately present or accessible in one's direct experience (Bruner & Olson, 1973). By means of language symbols and syntactic rules, an expository text objectives the author's knowledge concerning an area of reality (Ballstaedt, Mandl, Schnotz & Tergan, 1981; Britton & Black, 1985). In representational pictures, one can differentiate two kinds of pictures: (1) an illustration objectives an optical arrangement on a surface area, which corresponds to an area of reality in the relevant aspects of perception (Gibson, 1982). Examples of this kind are photos, sketches, and caricatures. (2) On the other hand, a visualization illustrates structures and relationships of the reality, which cannot be perceived under normal visual conditions. Such examples are hierarchies, flow charts, and organizational schemata. Since text and pictures are nowadays treated in parallel as two different media to convey knowledge, one mostly forgets that - in the evolution of cognition - writing developed from simple sketches (Földes-Papp, 1966; Klix, 1980).
