Patients with obsessive compulsive disorder (OCD) suffer from persistent intrusive thoughts (obsessions) and an urge to perform repetitive behaviours (compulsions) aimed at alleviating stress and anxiety. Obsessions can be thought of as a form of unhealthy “preoccupation”, which plays a key role not only in OCD, but also often in depression, anxiety and eating-related disorders.
The ventromedial prefrontal cortex (vmPFC) is crucial for effective valuation of important stimuli and our research has shown deficits in vmPFC functioning, specifically in regards to valuation in patients with OCD (Apergis-Schoute et al., 2017, 2018). This ultimately contributes to impaired performance on tasks that rely on external valuation. We hypothesize that specific preoccupations take up much of the vmPFC’s resources in OCD and other mental health disorders with strong preoccupying thoughts (Etkin et al., 2010).
The aim of the proposed project is to further our understanding of how preoccupation affects valuation in different anxiety-related patient groups. We will use a set of tasks investigating safety signals (CS-) – asking how much these patients can learn about stimuli that are safe. In addition, we believe that preoccupation interferes with everyday information processing and decision making - which we will test using a modified attentional task.
This project is aimed to tackle the dimension of preoccupation in anxiety related disorders that we believe burdens the vmPFC and interferes with everyday activities. We are looking for an enthusiastic PhD student who is invested in mental health research and is keen to be involved in paradigm design and computational modeling of data.
