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.

Measuring planning depth by playing 4-in-a-row

Sebastiaan Van Opheusden

A hallmark of human intelligence is the ability to plan multiple steps into the future. Similarly, mental disorders have been theorized to be related to dysfunction in model-based reinforcement learning or sequential planning. Studying those relations requires an experimental paradigm that enables inferring an individual’s ability and depth of planning. I will introduce a novel paradigm based on a two-player board game: 4-in-a-row. Alongside this game, I will present a computational cognitive model that can predict human choices, response times and eye movements. To showcase the strength of the game and the model to understand planning in healthy adults, I will present evidence for increased planning depth with expertise in both laboratory and large-scale mobile data. Finally, I will discuss how this game may enable insight into mental disorders and aid computational psychiatry.
