This volume presents a selection of the contributions to the Seventh Workshop on Informatics and Psychology. The theme of the workshop was Visualization in Human-Computer Interaction. Visualization is nowadays recognized as an important aspect of user-oriented human-computer interfaces. Both informatics and psychology are concerned with this topic. In informatics, the technology is being developed which makes visualization and interaction based on visual concepts feasible. Another important trend in informatics is the development of prototypical solutions. Visual programming, visual languages, graphical interfaces, visual representations and many other keywords characterize current efforts in this field. Psychologists are working on the question of how people represent knowledge visually and how they can take advantage of visual representations when solving tasks.

This volume presents a selection of contributions from the Fifth Workshop on Informatics and Psychology at Sch rding, Austria, May 1986, which focused on "Visual Aids in Programming." The lectures give a broad view of the state of the art in this new field of research and development spanning Cognitive Science, Informatics and Ergonomics, which draws its impact from the growing need for a deeper understanding of complex program structures and for better program design. The topics include the visualization of program structures, the discussion of psychological aspects, design problems of visual interfaces, and present implementations.
