Abstract

One of the most important functions of cognitive control is to continuously adapt cognitive processes to changingand often conflicting demands of the environment.Dopamine (DA) has been suggested to play a key role in the signaling and resolution of such response conflict.Given that DA is found in high concentration in the retina, color vision discrimination has been suggested as an index of DA functioning and in particular blue-yellow color vision impairment (CVI) has been used to indicate a central hypodopaminergic state. We used color discrimination (indexed by the total color distance score; TCDS) to predict individual differences in the cognitive control of response conflict, as reflected by conflict-resolution efficiency in an auditory Simon task. As expected, participants showing better color discrimination were more efficient in resolving response conflict.Interestingly, participants showing a blue-yellow CVIwere associated withless efficiency in handling response conflict. Our findings indicate that color vision discrimination might represent a promising predictor of cognitive controlability in healthy individuals.
