When we make decisions without getting feedback, we have to rely on our own internal subjective estimate of decision accuracy. This estimate, often referred to as confidence or metacognitive accuracy, plays a vital role in helping us adapt our behavior effectively. Most current models of metacognitive accuracy don’t consider that people adjust their level of cautiousness when they make decisions. However, we have shown that the level of cautiousness acts as a confounder in current measures of metacognitive accuracy. Recently, we introduced a novel approach to measure metacognitive accuracy called the ‘v-ratio model’. Here, we use a dynamic evidence accumulation framework to measure metacognitive accuracy while taking into account one’s level of decision caution. During this postdoc, i will use this model to address important questions in the field of metacognition such as whether metacognition is domain-general, whether confidence judgements are under strategic control and the role of post-decisional evidence accumulation in the neural basis of confidence.
