The mechanism of inhibition control in mathematical reasoning: a functional near-infrared spectroscopy study

Abstract

Background and objectives The ability to comprehend and engage in mathematical reasoning is a fundamental cognitive skill, central to problem-solving and critical thinking. However, the intricate cognitive processes underlying mathematical reasoning, particularly in relation to inhibitory control, have garnered increasing attention in recent research. While previous studies have explored this connection, there remains a need for a more comprehensive understanding of the interplay between inhibitory control and mathematical reasoning. This study explored the contribution of response inhibition and semantic inhibition to scientific reasoning by comparing the brain activation of the speeded-reasoning task of mathematical subdomain concepts with that of the Go/Nogo and Stroop tasks. Method Using functional near-infrared spectroscopy, oxygenated hemoglobin (oxy-Hb) was recorded in 28 subjects performing Go/Nogo tasks, Stroop tasks and speeded-reasoning tasks. The study was divided into two parts. In one part, subjects performed the Go/Nogo task and the Stroop task, and in the other part, subjects performed speeded-reasoning tasks. Results The results showed that the subjects had slower responses and lower accuracy when judging incongruent statements. The concentration of oxy-Hb in the brain region related to inhibition was increased. In addition, the oxy-Hb in reasoning incongruent nonmathematical statements was correlated to the Go/Nogo task, whereas the oxy-Hb in reasoning incongruent mathematical statements was correlated to the Stroop task. Conclusion This result supports the hypothesis that inhibitory control plays a role in the scientific reasoning of mathematical subdomain concepts, and both response inhibition and semantic inhibition are involved in suppressing the interference of mathematical misconceptions.
