This work investigates the extent to which human communication behavior is biologically determined rather than solely a product of social learning. James C. McCroskey, a prominent scholar in communication studies, utilizes the communibiological paradigm to argue that temperament and personality traits—which are largely inherited—serve as the primary drivers of how individuals interact. By synthesizing findings from behavioral genetics and communication research, the text challenges traditional social-learning models that dominate the field.

This text serves as a foundational document for the communibiological movement within communication studies, offering a dense, theoretical framework for scholars and advanced students. The subject matter points to a specialized, rigorous inquiry that prioritizes biological causality over traditional sociological explanations.
