Define 'persuasion' in the context of communication studies.

The definition of persuasion in the context of communication studies focuses on its role as a process whereby a communicator aims to influence another individual's beliefs, attitudes, intentions, or behaviors. Option B emphasizes this aspect clearly, stating it involves convincing someone to change their attitude or behavior. This highlights the intended outcome of persuasion, which is to transform the audience's perspective or actions based on the information presented.

While sharing information is certainly a component of communication, as indicated in option A, it does not inherently involve the effort to change someone’s views or actions, which is central to persuasion. Presenting facts, as suggested in option C, also lacks the definitive goal of inducing change; it's more about providing information rather than altering perceptions. Lastly, negotiating agreements, mentioned in option D, is often a distinct process aimed at reaching consensus rather than influencing attitudes directly, which further separates it from the core concept of persuasion in communication theories.
