Many people respond positively to a new drug just because of the enthusiasm surrounding it and their own expectations that the drug will make them feel better. This phenomenon is called the:

A) placebo effect.
B) novelty bias.
C) therapeutic window.
D) publication bias.

Placebo Effect

A beneficial effect, produced by a placebo drug or treatment, that cannot be attributed to the properties of the placebo itself, and must therefore be due to the patient's belief in that treatment.

Therapeutic Window

The range of a drug's dosage which provides efficacy without causing unacceptable adverse effects.

Novelty Bias

The tendency to prefer new or novel stimuli over familiar ones, which can influence learning and attention.
