Cognitive control is thought to be necessary for forgiveness processes.
To examine this correlation, highly impulsive participants, who often fail to inhibit feelings of revenge, received activating theta burst stimulation (TBS) of a classical cognitive control region of the brain, the right dorsolateral prefrontal cortex (rDLPFC). For testing forgiveness ability participants received verum TBS versus sham TBS in a randomized, double-blinded, within-subjects design. In both sessions, they first learned that there are fair and unfair opponents in an ultimatum game, and subsequently played a dictator game with reversed roles with the option to revenge or forgive the opponents from the previous game.
Contrary to our hypothesis, activating TBS did not increase forgiving behavior toward unfair opponents. However, it increased the generosity toward previously fair opponents.
As an explanation it is discussed that the TBS can only affect "cold" emotions such as greed, but not the "hot" emotions such as anger.
认知控制被认为是宽恕过程所必需的。
为了检验这种相关性，那些经常无法抑制报复感的高度冲动参与者接受了经典认知控制区域——右侧背外侧前额叶皮层（rDLPFC）的激活θ突发刺激（TBS）。为了测试宽恕能力，参与者在随机、双盲、自身对照设计中接受了真 TBS 与假 TBS。在这两个阶段，他们首先了解到在最后通牒博弈中有公平和不公平的对手，然后与之前的游戏中扮演相反角色的对手进行独裁者游戏，并可以选择报复或原谅他们。
与我们的假设相反，激活 TBS 并没有增加对不公平对手的宽恕行为。然而，它增加了对以前公平对手的慷慨程度。
作为一种解释，有人认为 TBS 只能影响“冷”情绪，如贪婪，而不能影响“热”情绪，如愤怒。
