abstract = {Selective visual attention requires an efficient
coordination between top–down and bottom–up attention
control mechanisms. This study investigated the behavioral
and neural effects of top–down focused spatial attention
on the coding of highly salient distractors and their
tendency to capture attention. Combining spatial cueing with
an irrelevant distractor paradigm revealed bottom–up based
attentional capture only when attention was distributed
across the whole search display, including the distractor
location. Top–down focusing spatial attention on the
target location abolished attentional capture of a salient
distractor outside the current attentional focus. Functional
data indicated that the missing capture effect was not based
on diminished bottom–up salience signals at unattended
distractor locations. Irrespectively of whether salient
distractors occurred at attended or unattended locations,
their presence enhanced BOLD signals at their respective
spatial representation in early visual areas as well as in
inferior frontal, superior parietal, and medial parietal
cortex. Importantly, activity in these regions reflected the
presence of a salient distractor rather than attentional
capture per se. Moreover, successfully inhibiting
attentional capture of a salient distractor at an unattended
location further increased neural responses in medial
parietal regions known to be involved in controlling spatial
attentional shifts. Consequently, data provide evidence that
top–down focused spatial attention prevents automatic
attentional capture by supporting attentional control
processes counteracting a spatial bias toward a salient
distractor.},
