【摘要】：行为人的意图动机是我们对日常行为的对错做出判断的重要依据。以往研究表明,左右侧颞顶联合区(TPJ)都可能与信念意图的整合加工能力相关,尤其是近年来越来越多的神经刺激研究为TPJ区域与心理状态归因能力之间的因果关系提供了证据。然而,这些研究在实验任务的选取,实验设计的优化,实验结论的稳健性上仍然有改进的空间。基于此,本研究开展了两个在设计上互相补充的实验。实验中被试的TPJ区域会接受一段时间的经颅直流电刺激,并完成一系列的道德判断任务,任务是由意图和结果,以及负性和中性2×2双变量构成的4种条件的故事:无伤人、伤人未遂、意外伤人和伤人成功,被试要对故事主角的行为做出谴责程度的道德判断。结合道德判断的谴责程度和决策时间数据发现,当人们在处理信念意图信息时,左右侧TPJ区域可能是协同互动、共同发挥作用的。在激活右侧TPJ并限制左侧TPJ的情况下,人们对负性结果的谴责程度变高,人们变得更加依赖于行为结果做出道德判断;而在限制右侧TPJ并激活左侧TPJ的情况下,人们对负性意图的谴责程度变高,人们变得更加依赖于行为者的动机做出道德判断。
[Abstract]:The intention motive of the perpetrator is an important basis for us to judge the right and wrong of our daily behavior. Previous studies have shown that both the left and right temporoparietal joint regions may be related to the ability of integrative processing of belief intention, especially in recent years, more and more neural stimulation studies have provided evidence for the causal relationship between the TPJ region and the mental state attribution ability. However, there is still room for improvement in the selection of experimental tasks, the optimization of experimental design and the robustness of experimental conclusions. Based on this, two complementary experiments were carried out in this study. In the experiment, the TPJ region was stimulated by transcranial direct current (TDC) for a period of time and completed a series of moral judgment tasks, which were composed of intention and result, as well as the story of four conditions of negative and neutral 2 脳 2 bivariate: no harm. Attempted, accidental, and successful, the subjects were asked to make a moral judgment of the extent to which the protagonist's actions were condemned. Combined with the condemnation degree of moral judgment and decision time data, it is found that when people deal with belief intention information, the left and right TPJ regions may interact and work together. In the case of activating the right TPJ and restricting the left TPJ, the degree of condemnation of the negative results increased, and people became more dependent on the results of behavior to make moral judgments, while in the case of restricting the right side of the TPJ and activating the left TPJ, Condemnation of negative intentions has increased, and people have become more dependent on the motivations of actors to make moral judgments.
