Lisa, a college student, had a great time at the party last night. She danced, sang karaoke, and even played the "Rock Band" video game—all behaviors that she had never exhibited in public before
She had been drinking the "punch" all night long, which she was told contained high levels of alcohol. Lisa was quite surprised to find out the next morning that the punch did NOT contain any alcohol. What concept may explain Lisa's behavior?
A) The Rosenthal effect
B) Illusory correlations
C) The nocebo effect
D) The placebo effect
Answer: D
Rationale: The placebo effect is a measureable and experienced improvement in health or behavior that cannot be attributable to a medication or treatment. Lisa's change in behavior after drinking the punch is similar to the reaction of patients when given a placebo that they expect to improve their health.
