Clinical assessments of individuals with @entity131 ( @entity131 ) typically report attentional difficulties, with distractibility prominent among these complaints. However, laboratory-based measures have often failed to find disproportionate distraction among @entity1 with @entity131 , as compared to control @entity1 . In this experiment, we tested 21 @entity1 hospitalized for rehabilitation following recent @entity131 and 21 demographically comparable control subjects on a visual reaction time go-no-go task in which the target was preceded or followed by a brightly colored moving visual stimulus, appearing above the target location. Early distractors actually served as warning stimuli, improving accuracy and speed for both @entity1 groups. Distractors occurring at or shortly after the time of target presentation had no significant impact on accuracy or response bias in either group, but did produce slowing of @entity138 that was significantly greater for @entity1 than for controls. The distractor that produced maximal slowing occurred 100 ms after the presentation of the target or foil. Repeated testing sessions led to reduction in the impact of the distractor and loss of the group difference in @entity138 impact. The degree of @entity138 slowing induced by distraction was modestly related to injury severity, as measured by the current score on the Disability Rating Scale, and the time until the @entity1 first followed verbal commands. There was also a trend of greater @entity138 slowing among individuals with focal orbitofrontal lesions, as assessed on neuroimaging studies. These results document a greater susceptibility to extraneous @entity227 among @entity1 with @entity131 in comparison to controls. The fact that this difference appears only in the @entity138 domain, and is greatest when the distractor follows the target, suggests that the primary impact of visual distractors is on response preparation and execution rather than target detection.
