One of the tests that make up the NAB Attention Module, the NAB Numbers & Letters Test is now available as a brief stand-alone assessment. Administration is relatively short and straightforward, incorporating letter cancellation and counting tasks to evaluate deficits in attention. The four subtests were developed to measure seven aspects of attention: sustained attention, psychomotor speed, selective attention, divided attention, information processing speed, impulsivity and disinhibition. The detailed Record Form guides examiners through the measure, allowing optimal portability and flexibility in a variety of evaluation settings.

  • Equivalent, parallel forms allow for ease of retesting while reducing the likelihood of practice effects.
  • Developed with the entire Neuropsychological Assessment Battery on a large standardisation sample (1,448 individuals).
    Scoring Templates aid evaluators to quickly score the measure.
