ID-100304526A new study published in Psychological Science shows that acetaminophen (Tylenol) may dull emotions. Although the matter in which Tylenol exerts its analgesic effect is unclear, previous research suggests that it acts on a part of the brain that influences emotions. To evaluate this claim, the randomized, controlled trial enrolled 85 participants, separating them into groups that would receive either 1,000 mg of Tylenol or placebo. Researchers then showed the participants a series of images and had them rate it on a scale from 0 (feeling little to no emotion) to 10 (feel an extreme amount of emotion). The participants in the Tylenol treatment group were less like to rate the images as extremely pleasant and unpleasant than the placebo group. What are your thoughts about this finding?
