Mental illness is frequently characterised by negative alterations in thought patterns. In depression, pessimistic biases lead to negative interpretations. In anxiety disorders, the future is thought to be dangerous. In paranoid states, intentions of others are bad. These thought biases appear to be intimately related to emotional biases. Indeed, a very powerful emotion regulation technique is to alter the contents of thoughts. However, the relationship between thoughts and emotions, and the neurobiological determinants of this mutual relationship remain incompletely understood. In this talk, I will discuss a number of mostly behavioural studies examining this relationship, starting with how affective reactions influence internal decisions about what to think about. These studies identified reactive aversive inhibition as influencing not only external decisions, but also internal decisions about which aspect of a plan to pursue. In order to gain a more detailed algorithmic view on the influence of affective information on thought processes than is possible with behaviour, I will then describe a more recent study using MEG decoding to examine how biases in representations during choice relate to individual differences. Finally, I will close by attempting to integrate these findings within a theoretical proposal assigning emotions a resource-rational role in cognitive processes.

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 (CEST). 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.
