Preface<br > This book is focnsed on the introductory course in oral communica-<br > tion. Its major emphasis is on person-to-group communication， or what is<br > commonly known as public speaking; but two forms of interpersonal<br > communication-small group communication and interviewing-are also<br > included. An effort has been made to achieve a balanced blending of<br > theoretical principles and suggestions for practical application， the as-<br > sumption being that students require theory to understand what they<br > are doing and why， yet also need and want examples of practical appli-<br > cation in order to develop an awarene~ of how that theory can be ap-<br > plied most effectively.<br > As a result of suggestions from the users of the first edition， this sec-<br > ond edition includes a considerable amount of new material. Four new<br > chapters have been added: Chapter 5， "Selecting the Subject and Pur-<br >poses"; Chapter 13， "Speaking to Inform"; Chapter 14， "Speaking to Per-<br > suade"; and Chapter 15， "Interpersonal Communication." Several new<br >communication topics have also been included within the chapters. The<br >new areas covered are effective and responsible listening (Chapter 2)，<br >audience analysis and adaptation ( Chapter 4)， and special fallacies (Chap-<br >ter 10).<br > Because Chapter 6， "Nonverbal Presentation，" contains information<br >most students need early in the course， it has been moved from Chapter<br >11 in the first edition to Chapter 6 in this edition. It is hoped this will<br >make the material more immediately useful to students in completing<br >their communicative assignments.<br > The fifteen chapters of this second edition are again devoted to the<br >principles involved in creating an aura of c，edibility for a speaker s ideas.<br >Two additional units， not directly related to this objective but of impor-<br >tance to students in many beginning courses， are included as appendixes.<br >The first appendix， "The Criticism of Speeches，" is appropriate for those<br > xi<br >
