Knowing our own minds: Metacognitive drivers of belief change
It is often assumed that resistance to changing one’s mind is due to social or motivational factors. The role of metacognitive capacities – knowing whether we are right or wrong – has received less attention.
In my talk I will present data from experiments that seek to understand the drivers of changes of mind about low-level perceptual decisions. These tasks allow us to characterise computations supporting the monitoring and revision of confidence in previous choices and delineate a prefrontal network engaged during simple changes of mind. By using psychophysical tricks to decouple confidence and performance, we further show that confidence in an initial decision acts to shape neural metrics of post-decisional processing.
I will examine how these processes account for variance in radical political views, and how metacognitive training may provide a route towards promoting belief flexibility.
