Final answer:
The statement that information which is colorful, interesting, and memorable tends to be more effective in changing attitudes is true, particularly in the context of peripheral route persuasion. Features like speaker credibility and message appeal also play crucial roles in persuasion effectiveness.
Step-by-step explanation:
Information that is colorful, interesting, and memorable is indeed more effective in changing attitudes, as vividness can play a significant role in persuasive messages. The statement can be considered true in the context of the peripheral route to persuasion. This route relies on cues, such as the attractiveness of the speaker or the use of celebrity endorsements, to influence attitudes and behaviors. However, in the central route of persuasion, the focus is on logical argumentation and factual information. Therefore, while vividness can enhance the effectiveness of persuasive messages, particularly in the peripheral route, it's not the only factor that contributes to persuasion.
Understanding the role of features such as the credibility of the source, the appeal of the message, and the susceptibility of the audience to these cues, is important for creating persuasive messages. Thus, the role of vividness must be seen in conjunction with other aspects such as the credibility of the speaker and the quality of the arguments presented.
