The Transcontinental Computational Psychiatry Workgroup (TCPW) organizes a monthly web-based meeting and a computational psychiatry satellite meeting with the Society of Biological Psychiatry. We hope to foster discussion and exchange between those involved in computational psychiatry—a rapidly growing, highly multidisciplinary field.

Videos of past meetings are here.

It has proved surprisingly hard to generalize from the rapid advances in our understanding of basic learning and decision making mechanisms to people?s real-life behavior. This is in part because the way such mechanisms manifest in real life depends on how they interact with other aspects of a person?s mental state and environmental circumstances. I will present recent work uncovering one such dynamical interaction, involving reward learning and mood: unexpected rewards affect mood and mood in turn affects responses to subsequent rewards. I will present behavioral and neuroimaging evidence for this two-way interaction, and develop a computational model that reveals its adaptive and maladaptive consequences: on one hand, it can ?correct? learning to account for global changes in the availability of reward in the environment; on the other hand, it might give rise to unstable oscillatory dynamics that result in emotional instability. I will introduce a novel smartphone-based experimental approach that allows directly studying how such real-life cognitive dynamics unfold over time.
