Book excerpt: Providing a current and comprehensive discussion of influential theories in communication, this text portrays the strengths and weaknesses of each theory. Communication Theories helps students see where these theories fit in the broad scheme of social inquiry and generally guides students in the evaluation and critique of theories in order to reach a more sophisticated level of understanding. Although it emphasizes theories developed by communication scholars, Communication Theories also includes work developed outside the field that has strongly influenced the work of communication scholars. The second edition has been completely updated to include new or enhanced coverage of post-colonialism, critical race theory, new generation social penetration theory, and mass media reception theory.
