The VSAT consists of four visual cancellation tasks that require the respondent to cross out letters and symbols that are identical to a target. 

  • Yields an overall attention score and provides separate scores for left- and right-side performance to assess visual field defects, unilateral spatial neglect, or syndromes that affect the perception of portions of the visual space.
  • Test-retest reliability over an average of 2 months is .95. The test correctly differentiated 84% to 86% of normal and brain-damaged subjects in validation and cross-validation samples. Sensitivity ranged from .78 to .88 and specificity ranged from .86 to .87.
  • Normative data are provided by age group.
