Primary objective: To examine the role of selective attention and visual perception in medicating inattentional blindness in a severe traumatic brain injured sample. Research design: Cross-sectional design with age and education matched control sample. Methods and procedures: Twenty participants with severe traumatic brain injury (n =10) and matched controls (n=10) completed a series of tests of focused attention (Stroop test), divided attention (Trail Making Test), visual perception (Visual Object and Space Perception Battery) and two tasks of inattentional blindness. Main outcomes and results: Th e group with severe TBI were significantly slower on the Stroop test and TMT and displayed significantly elevated Stroop interference and TMT ratio scores. On the inattentional blindness tasks, fewer TBI participants identified a distracting stimulus. Conclu sion: The results indicate severe TBI is associated with deficits to focused and divided attention with the finding of a potentially more debilitating impairment arising from reduced distractibility following severe TBI. © 2006 Taylor & Francis.
