The feeling of familiarity as a regulator of persuasive processing

Two experiments demonstrated that a subjective feeling of familiarity determined whether participants processed persuasive information analytically (systematically) or non-analytically (heuristically). In the first experiment, individuals unfamiliar with message content showed differential attitude change when strong versus weak arguments were presented, whereas individuals made familiar with the message through unrelated repetition failed to do so. These results were confirmed in a second study that manipulated familiarity through subtle repetition and eliminated procedural priming explanations of the effect. Implications of these findings for familiarity as a regulator of persuasive processing are discussed
