Wolff N, et al. - In view of the assumption that cognitive flexibility can, in certain cases, be useful to reinstate some form of rigid, repetitive behavior characterizing obsessive–compulsive disorder (OCD), researchers tested if, under such circumstances, cognitive flexibility is better in OCD patients than controls. Compared to controls, cognitive flexibility can be better in OCD. This could be observed in situations where superior abilities in the reactivation of repeating mental sets and difficulties to process new ones coincide. Intensified inhibitory control mechanisms may accomplish this. The results challenge the view on OCD, since OCD is not generally associated with cognitive inflexibility.
