Study Summary
The study will use transcranial magnetic stimulation (TMS) to investigate the causal role of different brain regions during visual perception. TMS is a well-established technique used by hundreds of labs in the world. The risks associated with the technique are well understood and can be minimized by strict adherence to established safety guidelines. In the proposed study, the investigators will use TMS to specifically address the topic of how metacognitive evaluation is supported by the two prefrontal areas: the dorsolateral prefrontal cortex (DLPFC) and the anterior prefrontal cortex (aPFC). The data will be collected from healthy adults and will ultimately deepen the investigator's understanding of the mechanisms behind the normal processes related to confidence generation and metacognition.
Primary Outcome
The average confidence difference for each delay condition and the 0 ms condition for each group (DLPFC or vertex). Confidence was self-reported together with the decision on a 4-point scale with the minimum score being one (not confident at all) and the highest score being four (very confident). The range of the scale is 1 (not confident at all) to 4 (very confident).
