Hirsch, Richard (1989) Argumentation, Information, and Interaction: Studies in Face-to-face Interactive Argumentation Under Differing Turn-taking Conditions. Gothenburg Monographs in Linguistics 7, Department of Linguistics, University of Göteborg. Although the thesis first appeared in 1989, I believe that the basic theoretical claims and empirical findings are still valid and, in fact, still rather under-researched. If I were to revise or rewrite the thesis, I would attempt to tone down the dominant information processing metaphor and go into greater depth and detail concerning the interdependence of the verbal and non-verbal aspects of the interactive argumentation. When approaching the text for the first time, I suggest first reading the summary which gives a good overview of the structure of the argument and a general outline of the results of the research presented in the thesis. The pagination of the on-line version of the thesis text differs from the pagination of the printed version. For citation or quotation purposes send me <[email protected]> the text to be cited or quoted and I will reply with the pagination details in the printed version of the text (available at certain university libraries).

The changes that have been undertaken have been basically cosmetic. The substance is fundamentally the same. The work and study that have lead up to this thesis have been in progress for over twenty years at six universities in four different countries. It is therefore impossible to remember and acknowledge all those who have influenced my thinking during this period. If by chance any of my former teachers and mentors should happen to read this thesis and remember me as their student they should hereby be acknowledged and thanked. This goes especially for Edelgard Weber who back in the middle of the sixties introduced me to Kleist's little essay 'Über die Allmähliche Verfertigung der Gedanken beim Reden'. As for the thesis itself - it is, as are most books, written to be read. The thesis is, however, also very much a book that has been read to be written. Without the generous efforts of many critical readers this thesis would have perhaps never seen the light of day. The principle reader of the thesis in many different shapes and sizes over a span of almost a decade has been my supervisor Jens Allwood. His influence on the form and substance of the thesis and his impact on my thinking in general are obvious in many places in the thesis. Next on the list of readers is Elisabeth Ahlsén who has been my co-supervisor in the final stages of the preparation of the thesis. She has been highly instrumental in helping me to get what I had to say in the proper order. Sven Strömqvist and Lars-Gunnar Andersson also read the thesis in manuscript and gave me many valuable comments and criticisms. Joakim Nivre, besides reading and giving valuable comments on the manuscript, helped immeasurably by checking the transcriptions of the examples against the video recorded data. In addition to this team of principle readers and commentators, the participants in the work-in-progress seminars have made many valuable contributions to the formation of my thoughts during discussions of preliminary forms of parts of the thesis. None of these readers should, of course, in any way be held responsible for what the writer of the thesis has made of all these helpful suggestions and comments. Others who have been instrumental in the production of the thesis have been Christina Andersson who helped with the transcription of the video recorded data and Tore Hellberg who put the manuscript into book form. Kathrine Patterson contributed the illustrations in chapter 4. Linda Schenck proof-read the English translations of the examples presented in the thesis. Åke Sander initiated me in the secrets and wonders of word-process- ing print-outs. To all of these readers, commentators, and assistants I want to extend a heartfelt word of gratitude. A special word of thanks goes to Camilla Lothigius, who made the illustrations in chapters 7, 8, and 9, and my daughter Sara, without whom not, for putting up with an absent father during all the summer holidays, weekends, and long nights that have gone into the vi writing of the thesis. Finally a word of acknowledgement to my parents; my mother for early on encouraging my interest in language in general and my father for arousing my interest in the analysis of argumentation in particular. Richard Hirsch vii Dialectic is at the same time an art of examination; for neither is the art of examination of the same nature as geometry, but it is an art which a man could possess even without any scientific knowledge. ...the art of examination is not knowledge of any definite subject, and it therefore follows that it deals with every subject; for all the arts employ also certain common principles. Accordingly, everyone, including the unscientific, makes some kind of use of dialectic and the art of examination; for all, up to a certain point, attempt to test those who profess knowledge. Aristotle On Sophistical Refutations, XI INTRODUCTION This thesis is a study of argumentation in situations of face-to-face spoken interaction. The situations analyzed consist of a formal television debate, a semi-formal television interview, and an informal conversational discussion. The investigation is based on an analysis of video recordings of the three situations. The formal television debate and television interview were broadcast in Swedish television just prior to the national referendum on nuclear energy in March 1980. There were three policy lines in the referendum; Line I, which was clearly for the use of nuclear energy, Line III, which was clearly against nuclear energy, and Line II, which was somewhere in between. The television debate was the only televised face-to-face confrontation between the policy lines during the referendum campaign. Prior to the television debate representatives from each of the policy lines were interviewed by a team of television reporters. The interview of the representatives for Line I has been selected for analysis in the thesis. The conversational discussion was video-recorded in 1980 in connection with a research project investigating cultural aspects of perspectives on natural resources (cf. Allwood 1981) which was conducted at the Department of Linguistics at the University of Göteborg. The discussion was held between non-specialist adolescents on the topic of the possibility of combining nature and technology. The three situations of argumentation constitute face-to-face interactive cases of what I will refer to as everyday argumentation. Everyday argumentation refers to argumentation concerning practical issues in law, politics, morals, economics, private and family affairs, medicine, the arts and sciences, etc., in other words, all types of argumentation except strictly theoretical logical or mathematical proofs or demonstrations. The thesis is basically an attempt to answer the question of what people are doing in face-to-face interactive argumentation based on an analysis of examples selected from the three specific cases of the television debate, the television interview, and the conversational discussion. The answer proposed is that face-to-face interactive argumentation can be view- ed as a type of collective information processing activity involving vocal and nonvocal information in search of a solution to a problem or an answer to a question. The problem 1 solving or answer seeking activity is carried out interactively according to the turn-taking conditions that obtain for the different occasions of argumentation. Overview of the Thesis The thesis consists of two parts. Part one is devoted to a presentation of a general theoretical model of interactive argumentation as collective information processing problem solving. Chapter 1 contains an overview of the general theoretical background for the thesis. The remaining chapters of part one contain a presentation of the particular information processing system model for interactive argumentation which will be used for the analysis of the empirical data in part two. A presentation of the information processing system model for problem solving is found in chapter 2. Chapter 3 contains a description of high level action plans in the problem solving that guide the search for a solution or an answer according to certain heuristic methods that help to reduce the range of interesting possibilities that may be profitably explored. Chapter 4 is devoted to explicating the logical and semantic operations that are applied in the projection and evaluation of prospective solutions or answers in the search activity. In chapter 5 it is shown how a solution of a problem or an answer to a question may involve solving subsidiary problems or answering subsidiary questions. This leads to the development of information in hierarchical recursively structured sets of logical and semantic operations referred to as courses of development. Chapter 5 contains an in- depth analysis of the internal hierarchical recursive structure of courses of development which are effected by a combination of vocal and nonvocal means in interactive face-to-face argumentation. Part two is devoted to empirical studies of interactive argumentation that exemplify and substantiate the theoretical claims in part one. Chapter 6 contains a discussion of the data and the methodology used in the empirical studies. Chapters 7, 8, and 9 consist of studies of selected examples from the television debate, the television interview, and the conversational discussion, respectively. Chapter 10 closes the thesis with a discussion of the main conclusions and findings and a comparison of the information processing problem solving model with other current theories of spoken interaction and argumentation. In this thesis I try to say something general but at the same time non-trivial about how information is developed in interactive argumentation. The presentation and discussion of the data in the thesis should be viewed as a part of a long-range project. The thesis constitutes the first major attempt at presenting an account of how vocal and nonvocal information work in combination in interactive argumentation. The account is primarily descriptive, although some tentative explanatory hypotheses are offered for the descriptive categories and generalizations. The descriptive labels used are developed with an aim of creating good flexible and general terms to describe the phenomena encountered in the study of argumentation. An attempt has been made at retaining the common sense basis of the terms to as great an extent as possible. This hopefully enhances their potential for explanation and understanding. Basically the whole thesis is an attempt to account for an intuitively perceived analogy between the functioning of an information processing system in terms of a recursive problem solving procedure and the vocal and nonvocal activity in situations of face-to-face interactive argumentation. 2 CHAPTER ONE THEORETICAL BACKGROUND This chapter contains a general overview of the theoretical foundations upon which the thesis rests. The chapter begins with a presentation and discussion of models of argumentation that have been proposed in the theoretical literature. This is followed by a presentation of the basic assumptions of relevant models of spoken interaction that will be used as a basis for comparison and discussion in the analysis of face-to-face interactive argumentation. The chapter closes with a presentation of the basic assumptions of the information processing framework adapted in the thesis and a discussion of previous studies of the relationship between body movement and speech. 1.1 Models of Argumentation Argumentation is a broad topic. It covers both written and spoken modes of communication and has been the subject of interest and study in philosophy and rhetoric in both western and eastern traditions since very early times. There are four basic types of models of argumentation that have been proposed. These may be referred to as 1) demonstrative argumentation, 2) non-demonstrative argumentation, 3) rhetorical argumentation, and 4) dia- lectical argumentation. These types of argumentation are related conceptually in terms of types and subtypes as illustrated in figure 1.1.
