It is often assumed that the promise of a monetary bonus improves cognitive control. We show that in fact appetitive motivation can also impair cognitive control, depending on baseline levels of dopamine synthesis capacity in the striatum. These data demonstrate not only that appetitive motivation can have paradoxical detrimental effects for cognitive control, but also provide a mechanistic account of these effects.
