Bonn-Melbourne Seminar Series in Decision Making and Computational Psychiatry

Subjective confidence and changes-of-mind in human decision-making

Abstract

Subjective confidence judgements are built looking back at our decisions (i), but also impact our decision- making in turn (ii). (i) In a first series of empirical studies, I will consider that confidence can be computed across a number of hierarchical levels, from local confidence in a given decision to self-beliefs about our abilities on a given task up to global (trait) self-confidence. I will also show that local and task-based confidence differently map onto trait psychiatric symptoms that naturally fluctuate in the general population. (ii) In a second series of empirical studies, I will show how local confidence impacts change-of-mind decisions at short time scales. Behavioral, MEG and pupil data reveal that when participants are in control of the evidence sampled for deciding, they need more evidence against their current beliefs to change their mind, but change their mind with reduced confidence, and are more likely to confirm a change of mind on the next decision. Together these results characterise different forms of metacognitive confidence, and suggest that global components of metacognition, even more than local, may impact our behavior.

About the series:
The Bonn-Melbourne Seminar Series in Decision Making and Computational Psychiatry is part of the joint doctoral training and research collaboration at the intersection of decision neuroscience and computational psychiatry between the University of Bonn (spokesperson: Ulrich Ettinger) and the University of Melbourne (spokesperson: Carsten Murawski).

The online seminars take place on Thursdays at 9:00 am (CET)/7 pm (AEDT). Talks are 45 minutes long plus 15 minutes for questions and discussion. The target audience consists of students, PhD students, postdocs and researchers from both Bonn and Melbourne who have an interest in decision-making and computational psychiatry research.
