Two hypotheses were tested using a novel individual differences approach, which identifies rate-limiting brain regions, that is, brain regions in which variations in neural activity predict variations in behavioral performance. The first hypothesis is that the rate-limiting regions that support the production of lies about oneself (self-related) are partially distinct from those underlying the production of lies about other individuals (other-related). The second hypothesis is that a cingulate-insular-prefrontal network found to be rate-limiting for interference tasks is involved in both types of lies. The results confirmed both hypotheses and supported the utility of this individual differences approach in the study of deception in particular, as well in the study of complex cognitive phenomena more generally.
我们使用一种新颖的个体差异方法对两个假设进行了检验，该方法能够识别限速脑区，即神经活动的变化可预测行为表现变化的脑区。第一个假设是，支持编造关于自己的谎言（自我相关）的限速脑区与支持编造关于他人的谎言（他人相关）的限速脑区部分不同。第二个假设是，一个被发现对干扰任务具有限速作用的扣带回-脑岛-前额叶网络参与了这两种类型的谎言编造。结果证实了这两个假设，并支持了这种个体差异方法在欺骗研究中，特别是在更广泛的复杂认知现象研究中的效用。
