RIT™

Reynolds Interference Task™

Purpose: Measures complex processing speed

Format: Paper and pencil

Age range: 6 years to 94 years

Time: 5 minutes to administer and score

DETAILS:

The RIT is a Stroop-style test of complex processing speed that measures general neuropsychological integrity. It adds a layer of cognitive processing tasks—inhibition and attention-shifting—to simple tasks, which makes them more complex and thus more indicative of cognitive flexibility and selective attention.

The mental effort required for the RIT allows clinicians to measure the effects of TBI, stroke, brain insult or injury, dementia, Alzheimer's disease, and brain tumors. Alternately, the RIT can be used as a measure of attention and complex processing speed deficits and as a rapid means of measuring recovery from concussion.

Features and Benefits

  • Features two subtests that combine to provide a Total Correct Index, which offers greater coverage, enhanced consistency, and more reliability than a single subtest.

  • Includes reliable change scores and discrepancy scores with the Reynolds Intellectual Assessment Scales, Second Edition (RIAS-2), a trusted measure of intelligence.

  • Covers a wide age range (6-94 years) in one test.

  • Requires minimal motor demand.

  • Takes just five minutes to administer and score.
