Participants in a Study Freely Engage in a Behaviour That

Multiple Choice

Participants in a study freely engage in a behaviour that is contrary to their attitudes. This behaviour causes an increase in physiological arousal, but the experimenter tells the participants that this arousal is the product of a placebo pill they have taken.

A) the theory of planned behaviour
B) self-justification
C) social identity theory
D) cognitive dissonance
