Attentional blink and putative noninvasive dopamine markers: Two experiments to consolidate possible associations.

Adaptive behavioral control involves a balance between top-down persistence and flexible updating of goals under changing demands. According to the metacontrol state model (MSM), this balance emerges from the interaction between the frontal and the striatal dopaminergic system. The attentional blink (AB) task has been argued to tap into the interaction between persistence and flexibility, as it reflects overpersistence-the too-exclusive allocation of attentional resources to the processing of the first of two consecutive targets.
