This thesis sets out to examine perceptual structures in works of "Neuer Realismus". In 1965 a group of authors became known both under this name and also under that of "Kölner Schule". Their works were published by Kiepenheuer & Witsch, Cologne. The publisher's reader in charge of these authors was Dieter Wellershoff who published working notes in the house magazine of Kiepenheuer & Witsch under the title "Neuer Realismus". The fictional work of this group of writers corresponded largely to these notes. In the article Wellershoff made a special plea for phenomenological modes of perception and writing. The critics soon regarded "Neuer Realismus" as a successor to the French Nouveau Roman. It is one of the main aims of this thesis to show what "Neuer Realismus" and the Nouveau Roman have in common and what differentiates them. We should like to examine what similarities each work of the "Neuer Realismus" shows with the Nouveau Roman, how far it follows Vellershoff 's working notes and in what way it remains a work in its own right. We have therefore attempted a predominantly immanent interpretation. The criteria of this thesis are phenomenological modes of perception, particularly with regard to Robbe-Grillet1s "Ecole du regard", the examination of the polarities of subjectivity and objectivity, and the role of the author, and/or the first person narrator, who reflects him and his medium. Because of these criteria there suggested itself the following selection of authors and works, which could be dealt with in an exemplary and meaningful manner within the framework of the thesis: Nicolaus Bom, Rolf Dieter Brinkmann, Giinter Steffens, Dieter Wellershoff. The thesis deals first with the term "Neuer Realismus" and its contemporary literary context. At the same time it juxtaposes "Neuer Realismus" and Nouveau Roman, considering common aspects as well as divergent ones, and referring in particular to the theoretical writing of Wellershoff and Robbe-Grillet. Then follows a discussion of the individual works vhich are, with the exception of Wellershoffs "Die Schattengrenze", first novels or collections of short stories.
