某些问题对正常人的头脑来说是天生困难的。然而，矛盾的是，对于那些有着不同寻常头脑的人来说，这些都是毫不费力的。我们发现，非侵入性脑刺激的非典型协议能够解决以前无法解决的问题。上个世纪的大多数研究发现，没有参与者能解决9点问题--我们证实了这一事实。但在10分钟的右侧经颅直流电刺激（tDCS）中，超过40%的参与者这样做了。具体来说，尽管没有参与者在刺激前或假刺激下解决了这个极其困难的问题，但33名参与者中有14名在左前颞叶的阴极刺激和右前颞叶的阳极刺激下解决了这个问题。这一发现表明，我们的刺激范式可能有助于减轻认知偏见，或者处理更广泛的任务，尽管看似简单，但由于我们的认知构成而非常困难。(C)2012爱思唯尔爱尔兰有限公司保留所有权利。
Certain problems are inherently difficult for the normal human mind. Yet paradoxically they can be effortless for those with an unusual mind. We discovered that an atypical protocol for non-invasive brain stimulation enabled the solution of a problem that was previously unsolvable. The majority of studies over the last century find that no participants can solve the nine-dot problem - a fact we confirmed. But with 10 min of right lateralising transcranial direct current stimulation (tDCS), more than 40% of participants did so. Specifically, whereas no participant solved this extremely difficult problem before stimulation or with sham stimulation, 14 out of 33 participants did so with cathodal stimulation of the left anterior temporal lobe together with anodal stimulation of the right anterior temporal lobe. This finding suggests that our stimulation paradigm might be helpful for mitigating cognitive biases or dealing with a broader class of tasks that, although deceptively simple, are nonetheless extremely difficult due to our cognitive makeup.
