      abstract     = {Observers can learn locations where salient distractors
                      appear frequently to reduce potential interference—an
                      effect attributed to better suppression of distractors at
                      frequent locations. But how distractor suppression is
                      implemented in the visual cortex and within the
                      frontoparietal attention networks remains unclear. We used
                      fMRI and a regional distractor-location learning paradigm
                      with two types of distractors defined in either the same
                      (orientation) or a different (color) dimension to the target
                      to investigate this issue. fMRI results showed that BOLD
                      signals in early visual cortex were significantly reduced
                      for distractors (as well as targets) occurring at the
                      frequent versus rare locations, mirroring behavioral
                      patterns. This reduction was more robust with same-dimension
                      distractors. Crucially, behavioral interference was
                      correlated with distractor-evoked visual activity only for
                      same- (but not different-) dimension distractors. Moreover,
                      with different- (but not same-) dimension distractors, a
                      color-processing area within the fusiform gyrus was
                      activated more when a distractor was present in the rare
                      region versus being absent and more with a distractor in the
                      rare versus frequent locations. These results support
                      statistical learning of frequent distractor locations
                      involving regional suppression in early visual cortex and
                      point to differential neural mechanisms of distractor
                      handling with different- versus same-dimension distractors.},
