Test of Variables of Attention
Pronunciation: TOH-vah
Also written as: TOVA — Test of Variables of Attention
A computerized continuous performance test that measures sustained attention, impulsivity, and response variability.
Full Definition
The Test of Variables of Attention (TOVA) is a computerized continuous performance test designed to assess attention-related variables including sustained attention, response time variability, commission errors (impulsivity), and omission errors (inattention). The test requires participants to respond to target stimuli while inhibiting responses to non-target stimuli over a 21.6-minute period. The TOVA provides objective, quantitative measures that are compared to age and gender-matched normative data, yielding standard scores and confidence intervals. It is commonly used in ADHD assessment, monitoring medication effects, and evaluating attention deficits following brain injury. The test's standardized administration and scoring procedures make it valuable for research and clinical practice, though it should be interpreted within the context of comprehensive neuropsychological evaluation.
