Changes with respect to placebo condition under levodopa and risperidone (means ± SEM) for music-related reward responses. (A) Amount of time reporting chills, high pleasure (HP), low pleasure (LP), and no pleasure (NP) real-time ratings (i.e., while listening to each song, including self- and experimenter-selected songs; e.g., risperidone and levodopa, respectively, decreased and increased by 43% and 65% the time reporting chills with respect to the placebo condition). Chills values include chills responders only; HP, LP, and NP values include the entire sample. (B) EDA changes associated with high-pleasure real-time ratings. (C) Motivational ratings, i.e., willingness to spend money for each excerpt. *P < 0.05.
