The Test of Variables of Attention (T.O.V.A.; R. A. Leark, T. R. Dupuy, L. M. Greenberg, C. L. Corman, _ C. L. Kindeschi, 1996) is a continuous performance test used widely to help diagnose @entity71 ( @entity71 ) in both hearing and deaf @entity1 . The T.O.V.A. previously has been normed only on the hearing population. The T.O.V.A. performance of 38 prelingually and severely-to-profoundly deaf young adults and 34 hearing young adults who did not have @entity71 was examined in this study. Deaf and hearing @entity1 did not differ on the T.O.V.A. omission variables. However, deaf @entity1 had significantly lower d' scores than hearing @entity1 , indicating reduced perceptual sensitivity to the distinction between target and distractor stimuli. Consistent with the existing literature on attentional reorganization in the deaf population, this result was interpreted as indicating a @entity2319 -related reduction in attention to centrally presented stimuli. Deaf @entity1 also showed 2 to 3 times more commission errors than hearing @entity1 and displayed a higher incidence of anticipatory errors. These results suggest a @entity2319 -related increase in impulsivity at the time of response initiation. Beta score analysis confirmed that deaf @entity1 adopted an overall less conservative (more impulsive) response criterion that contributed to their total elevated commission errors. However, a portion of the commission errors was secondary to their reduced d', not to increased behavioral impulsivity. Separate factor analyses of the standard T.O.V.A. variables revealed highly similar factor structures for deaf and hearing @entity1 , indicating similar construct validity of the T.O.V.A. for both groups. The evidence for increased inattention and impulsivity in a non- @entity71 deaf sample are interpreted in the context of an adaptive attentional reorganization due to @entity2319 . Along with the factor analytic results, these considerations suggest that separate T.O.V.A. norms must be developed for the deaf population to avoid overdiagnosis of @entity71 in deaf individuals.

Deaf adults without XXXX display reduced perceptual sensitivity and elevated impulsivity on the Test of Variables of Attention (T.O.V.A.).
