Unique Electroencephalography (EEG) Markers of Habit Behaviors in Obsessive-Compulsive Disorder (OCD)
Sponsor: Shanghai Mental Health Center
Summary
This study focuses on explaining the occurrence and development of compulsive behaviors from habit hypothesis. Investigators will study both OCD patients and healthy individuals using Hardwick's forced-response time task(2019), the habit Go/No-Go task, and the Intra-Extra Dimensional Set Shift task. Investigators aim to explore the cognitive abilities and differences between OCD patients and healthy controls in these three tasks. Control variables will include participants' levels of anxiety, depression, and stress, as well as sense of incompleteness and intolerance of uncertainty levels. By examining the differences in habit formation and expression abilities between OCD patients and healthy controls, and exploring the specific brain electroencephalographic activity processes in OCD patients, investigators hope to reveal the abnormal neural activity in habit-related circuits in OCD patients. This could provide new insights for the diagnosis and treatment of OCD.

habit formation training
Participants need to perform habit formation exercises for 4 consecutive days. During the exercises, participants will see a picture stimulus and need to learn the corresponding key press. Each day, participants will spend 30 minutes on the training.
