进行了一项功能性磁共振成像（fMRI）研究，参与者进行了一系列复杂的心理计算，持续约2分钟。思维理性的自适应控制（ACT-R）模型[安德森，JR.人类的思想如何在物质宇宙中产生？纽约：牛津大学出版社，2007年]，成功地适应了乳酸菌的分布。该模型预测了与ACT-R理论中的模块相关的六个大脑区域的fMRI信号。该模型的预测证实了梭状回区域，反映了视觉模块，前额叶区域，反映了检索模块，前扣带回区域，反映了目标模块。此外，反映手动模块的运动区域的唯一显著偏差是预期的手部运动。相比之下，预测相对较差的顶叶区域，反映了想象模块和尾状核区域，反映了程序模块。这些穷人适合可能的解释进行了讨论。此外，还进行了探索性分析，以找到可能与模块预测相对应的区域。
A functional magnetic resonance imaging (fMRI) study was performed in which participants performed a complex series of mental calculations that spanned about 2 min. An Adaptive Control of Thought—Rational (ACT-R) model [Anderson, J. R. How can the human mind occur in the physical universe? New York: Oxford University Press, 2007] was developed that successfully fit the distribution of latencies. This model generated predictions for the fMRI signal in six brain regions that have been associated with modules in the ACT-R theory. The model’s predictions were confirmed for a fusiform region that reflects the visual module, for a prefrontal region that reflects the retrieval module, and for an anterior cingulate region that reflects the goal module. In addition, the only significant deviations to the motor region that reflects the manual module were anticipatory hand movements. In contrast, the predictions were relatively poor for a parietal region that reflects an imaginal module and for a caudate region that reflects the procedural module. Possible explanations of these poor fits are discussed. In addition, exploratory analyses were performed to find regions that might correspond to the predictions of the modules.
