Papers on exploration and model-free behaviour

I had the pleasure to co-author two papers that provide substantial new insight nto the mechanisms underlying cognition.

In a recent paper by Nitzan Shahar, he assesses the reliability of the famous ‘two-step task’ and describes how to improve the reliability of this test. This is critical if we want to adequately capture the functioning of multiple reasoning-systems in health and disorder.

In a second paper by Philipp Schwartenbeck, he uses computational modelling to describe to forms of goal-directed exploration. While one of them is to learn environmental contingencies, the other form helps determine in which state an agent is. These forms of goal-directed exploration thus serve different functions and are believed to be important contributors to decision making.
