Step-by-step explanation:
The TV advertisements for Tylenol that use an attractive famous actor who portrays a doctor in a television series to promote the product are using the peripheral route according to the elaboration likelihood model.
The peripheral route is a type of persuasion that relies on superficial cues such as the attractiveness of the person promoting the product, rather than the content of the message itself. In this case, the advertisement is using a famous actor to grab the viewer's attention and create a positive association with the product. The central route, on the other hand, relies on a more thoughtful consideration of the message and its arguments, rather than superficial cues.
Fear appeal is a type of persuasive message that tries to scare people into taking action. The foot-in-the-door technique is a persuasion strategy that involves getting a person to agree to a small request before asking for a larger one. Neither of these techniques is being used in the scenario described.
