About This Product
BY CECIL R. REYNOLDS, PHD
Based on time-tested techniques, the CTMT is a set of five standardized visual search and sequencing tasks that are heavily influenced by attention, concentration, resistance to distraction, and cognitive flexibility (or set-shifting). Because these tasks are linked to a wide range of neuropsychological deficits, the CTMT is one of the most clinically useful instruments you’ll find.
Trail-making requires the examinee to connect a series of stimuli (numbers or letters) in a specified order as fast as possible. In Trail 1, for example, he or she draws a line connecting the numbers 1 through 25 in order. Trail 2 presents the same task, but this time 29 distractors also appear on the page. Trails 3, 4, and 5 alter the basic task in other ways—by introducing irrelevant line drawings, for example, or presenting numbers as words rather than numerals. The score for each trail is the number of seconds required to complete the task. Individual trail scores are pooled to obtain a composite score.
The CTMT is extremely sensitive to neurological insult, disease, injury, and dysfunction, including the subtle neuropsychological problems often present in individuals with learning disabilities.
