The study examined the perception of facial expressions of different emotional intensities in obsessive-compulsive disorder (OCD) subtypes. Results showed that the High Risk Assessment and Checking subtype was more sensitive in perceiving the emotions fear and happiness. This suggests that altered affective processing may underlie the clinical manifestation of OCD.
