What this topic is asking
Topic 4.2 covers attitudes, how they form, how they change, and how they relate to behavior. The College Board wants cognitive dissonance, the foot-in-the-door and door-in-the-face compliance techniques, the central and peripheral routes to persuasion, and related concepts like stereotypes, belief perseverance, and the halo effect.
Attitudes and behavior
Cognitive dissonance
Compliance and persuasion techniques
The exam expects specific named techniques:
- Foot-in-the-door technique: start with a small request that is easy to grant; once people agree, they are more likely to agree to a larger request, to stay consistent.
- Door-in-the-face technique: start with a large, unreasonable request that is refused; the smaller follow-up request then looks reasonable by comparison.
- Central route to persuasion: changing attitudes through strong, logical arguments and evidence that the audience considers carefully; produces durable change.
- Peripheral route to persuasion: changing attitudes through superficial cues (an attractive or credible source, a catchy slogan), without deep thought; produces weaker change.
Other attitude phenomena
- Stereotype: a generalized belief about a group, which can bias perception of individuals.
- Belief perseverance: clinging to a belief even after the evidence for it is discredited, often via confirmation bias (seeking information that confirms the belief).
- Halo effect: letting one positive trait (such as attractiveness) color our overall impression of a person.
The thread running through this topic is that attitudes are not fixed and private; they shift under social and cognitive pressure, and skilled persuaders exploit predictable levers. Cognitive dissonance shows attitudes bending to fit behavior; the compliance techniques show how small or extreme initial requests reshape what we agree to; and the two routes of persuasion explain why a careful argument and a glossy advertisement both work but on different people and with different durability. For the exam, a scenario about someone changing an attitude to match what they did is dissonance; a small request preceding a big one is foot-in-the-door; an advertisement leaning on a celebrity rather than facts is the peripheral route. Naming the exact mechanism is what scores.
Try this
Q1. Explain cognitive dissonance and how people typically resolve it. [2 points]
- Cue. The discomfort from conflicting actions and attitudes; people usually resolve it by changing the attitude to match the behavior.
Q2. Distinguish the central from the peripheral route to persuasion. [1 point]
- Cue. The central route persuades through logical arguments and evidence; the peripheral route persuades through superficial cues like an attractive source.

AP 2024 (style)1 marksMultiple choice. A person who has always disliked exercise begins working out daily because of a new job requirement, and soon reports actually enjoying it and valuing fitness. This change in attitude to match behavior is best explained by which concept? (A) The mere exposure effect (B) Cognitive dissonance (C) The fundamental attribution error (D) The peripheral route to persuasion (E) Belief perseveranceShow worked answer →
The answer is (B) Cognitive dissonance.
Cognitive dissonance is the discomfort felt when actions and attitudes conflict. To reduce it, people often change the attitude to match the behavior. Exercising despite disliking it creates dissonance, which is eased by coming to value exercise.
(A) the mere exposure effect is increased liking from familiarity, not attitude-behavior conflict. (C) the fundamental attribution error concerns explaining behavior. (D) the peripheral route is persuasion via superficial cues. (E) belief perseverance is clinging to a belief despite contrary evidence.
AP 2023 (style)4 marksConcept-application free-response question. A campaign tries to change people's behavior. Explain how EACH of the following could be used or could occur: cognitive dissonance, the foot-in-the-door technique, the central route to persuasion, and the peripheral route to persuasion.Show worked answer →
A 4-point concept-application FRQ; one point per term.
Cognitive dissonance (1): inducing people to act against an attitude so the resulting discomfort pushes them to change the attitude to match.
Foot-in-the-door technique (1): getting a small initial commitment so people are more likely to agree to a larger later request.
Central route to persuasion (1): persuading through strong, logical arguments and evidence that the audience thinks about carefully.
Peripheral route to persuasion (1): persuading through superficial cues such as an attractive spokesperson or catchy slogan.
Markers reward each term being correctly defined AND tied to the campaign.
