心理学和行为经济学理论表明，人们经常做出非理性和次优的决定。为了描述某些决定，人们经常使用与痛苦有关的词（“伤害”，“痛苦”）。神经科学证据表明，参与身体疼痛和决策的系统之间存在共同的重叠。然而，以前没有研究探讨过旨在减少身体疼痛的药物干预是否可以减少决策的痛苦。目前的研究填补了这一空白，让参与者服用物理止痛药对乙酰氨基酚或安慰剂，然后将他们暴露在已知会产生认知失调（实验1）或损失厌恶（实验2）的情况下。这两个实验都表明，对乙酰氨基酚减少了决策的痛苦，这表现在认知失调带来的态度变化较小，以及出售个人物品时的售价较低。(C)2014爱思唯尔公司All rights reserved.
Psychological and behavioral economic theories have shown that people often make irrational and suboptimal decisions. To describe certain decisions, people often use words related to pain ("hurt," "painful"). Neuroscientific evidence suggests common overlap between systems involved in physical pain and decision-making. Yet no prior studies have explored whether a pharmacological intervention aimed at reducing physical pain could reduce the pain of decision-making. The current investigation filled this gap by assigning participants to consume the physical painkiller acetaminophen or placebo and then exposing them to situations known to produce cognitive dissonance (Experiment 1) or loss aversion (Experiment 2). Both experiments showed that acetaminophen reduced the pain of decision-making, as indicated by lower attitude change that accompanies cognitive dissonance and lower selling prices when selling personal possessions.
