LUTZ, Fla., March 21, 2017 /PRNewswire/ -- The new Reynolds Interference Task (RIT), the latest test from popular author Cecil R. Reynolds, PhD, evaluates complex processing speed and general neuropsychological integrity. It is ideal for measuring the effects of traumatic brain injury, stroke, dementia, Alzheimer's disease, and brain tumors quickly and comprehensively. It is also useful as a measure of attention and complex processing speed deficits and as a rapid means of measuring recovery from concussion.
Most existing measures of speeded processing are exceedingly simple in that they measure how quickly one can perform simple tasks that, given unlimited time, almost everyone would complete perfectly. The RIT adds a layer of cognitive processing difficulty—inhibition and attention-shifting—to simple tasks, which slows performance and requires extra mental effort, making the tasks more complex and thus more indicative of cognitive flexibility and selective attention.
"Mental speeded processing, also referred to as decision speed, can be a crucial contributor to the diagnostic process for a variety of disorders," stated R. Bob Smith III, PhD, PAR chairman and CEO. "The RIT's two subtests provide greater coverage, enhanced consistency, and more reliability than similar measures that feature a single subtest."
The RIT features two timed Stroop-style subtests, Object Interference and Color Interference, which combine to provide a Total Score. It was designed to provide continuity of measurement across a wide age range, making it appropriate for use with individuals ages 6 to 94 years. The subtests require minimal motor demand and can be administered in just 90 seconds.
