Written expressly for undergraduate courses, An Introduction to the Dark Side of Interpersonal Communication provides students with a comprehensive yet approachable introduction to the nature, functions, antecedents, and outcomes of dark side events and behaviors in close relationships. The book features a balance of relatable examples and academic, theoretical, research-based approaches to help students thoughtfully and critically consider interpersonal processes and their impacts on relationships and communication. After a general introduction to the dark side perspective, the book discusses a number of events—and potential responses—that can arise within interpersonal relationships, including relationship transgressions such as hurtful communication, jealousy, deception, infidelity, aggression and violence, stalking, teasing, destructive conflict, and more. Students learn about the vital role of communication in these instances and how, in select cases, constructive communication practices can mitigate the incidences and the effects of dark side events in interpersonal relationships. Chapter introductions, vignettes, discussion questions, and theoretical considerations enhance the student learning experience and provide ample opportunities for in-class dialogue and critical thought. An Introduction to the Dark Side of Interpersonal Communication is an innovative and insightful textbook well suited for undergraduate courses in communication.
