Stuck in the loop: Classification of Ritualized Motor Patterns in OCD and Controls

Research output: Contribution to conferencePoster

According to several behavioral and cognitive and behavioral ritual theories, individual and collective rituals can function as reliable signals. Rituals are characterized by a set of perceptually accessible motor features (i.e., stereotypy, repetitions, insertion of irrelevant acts) that has specific perceptual and cognitive effects. One possible effect is facilitation of bottom up classification. This has previously been supported by simulations of a human-like perceptual system and circumstantial experimental evidence. In this study we wanted to test the clinical relevance of these insights for Obsessive Compulsive Disorder (OCD). Although OCD is characterized by an excessive amount of motor rituals, diagnosis of OCD relies heavily upon psychological evaluation of the patient’s subjective report of the severity of recurrent thoughts and repetitive behaviors. While this diagnostic method is essential to the treatment of patients suffering from OCD, automated classification tools based on everyday motor patterns has the potential of increasing diagnostic accuracy and flexibility.
