我们使用功能性磁共振成像（fMRI）比较了参与者在有和没有欧拉图的三段论解决任务中的表现和大脑激活变化。我们的实验表明，当欧拉图存在时，（i）在任务中的反应时间显着短于那些在通常的推理任务，仅包括句子，和（ii）激活的幅度在左额中回（近BA 10），左下PFC（近BA 47），左背PFC（BA 6）减少。结果（i）提供了证据，即使被试在推理任务中处理句子和图表信息时，也会发生认知卸载。结果（ii）表明，复杂的推理过程可以用简单的图表操作来代替。有人认为，认知细节，没有完全指定的行为研究可以突出使用神经科学的方法。
We compared participant performance and brain activation changes during a syllogism-solving task with and without Euler diagrams, using functional magnetic resonance imaging (fMRI). Our experiment showed that when Euler diagrams were present, (i) response times in the task were significantly shorter than those in the usual reasoning task comprising only sentences, and (ii) the magnitude of activation in the left middle frontal gyrus (near BA 10), left inferior PFC (near BA 47), and left dorsal PFC (BA 6) was reduced. Result (i) provides evidence for the occurrence of cognitive offloading even when participants handle information of both sentences and diagrams in reasoning tasks. Result (ii) suggests that complex processes of inferences can be replaced by simple diagram manipulation. It is argued that cognitive details that are not fully specified by behavioral studies can be made salient using neuroscientific methods.
