Exploring the Neural Basis of Fast and Slow Logic

Résumé

Dual-process theories characterize thinking as an interaction between intuitive and deliberate thought processes. For instance, logical reasoning is assumed to require effortful deliberate thinking. In recent years, however, a number of findings obtained with new behavioral paradigms have questioned the traditional dual-process characterization. A key observation is that people can process logical principles intuitively without deliberation. However, the nature of this newly discovered fast logical reasoning is not clear. Indeed, its neural basis has not been explored. We thus aim to address this shortcoming in a functional magnetic resonance imaging (fMRI) study. Using the bat-and-ball task, we contrasted fast (intuitive) and slow (deliberate) trials to investigate whether intuitive and deliberate processes recruit different brain areas. Two groups of participants (Correct and Incorrect, based on a behavioral pretest) solved bat-and-ball problems while in an fMRI scanner. Half of the trials were slow trials in which participants got 20s to deliberate. The other half were fast trials in which they only had 5s to think and needed to rely on intuitive processing. A short training intervention mid-study also explained the correct solution strategy to participants. Our main goal is to identify the unique neural basis of correct intuitive reasoning for the first time. We present preliminary results of the intervention suggesting that the Anterior Cingulate Cortex (ACC) is involved in intuitive processing.
