Statistical distractor learning modulates perceptual sensitivity.

ABSTRACT: The present study used perceptual sensitivity (d') to determine the spatial distribution of attention in displays in which participants have learned to suppress a location that is most likely to contain a distractor. Participants had to indicate whether a horizontal or a vertical line, which was shown only briefly before it was masked, was present within a target shape. Critically, the target shape could be accompanied by a singleton distractor color, which when present appeared with a high probability at one display location. The results show that perceptual sensitivity was reduced for locations likely to contain a distractor, as d' was lower for this location than for all other locations in the display. We also found that the presence of an irrelevant color singleton reduced the gain for
