[Press Release] Neural Correlates of Belief-Bias Syllogistic Reasoning

In research conducted in the CARLS, Takeo Tsujii, associate professor of Keio University's Graduate School of Human Relations, and Shigeru Watanabe, professor of Keio University's Faculty of Letters and Graduate School of Human Relations, examined the neural correlates of dual-task effect in belief-bias syllogistic reasoning, using near-infrared spectroscopy (NIRS). They found that the high-load secondary task decreased right inferior frontal cortex (IFC) activity during incongruent trials. In addition, correlation analysis found subjects with enhanced right IFC activity could perform better in the incongruent reasoning trials, though subjects for whom right IFC activity was impaired by the secondary task could not maintain better reasoning performance. The study was published in Brain Research Journal (Vol. 1287, pp 118-125).
