CTMT

The CTMT is a set of five visual search and sequencing tasks that focus on attention, concentration, resistance to distraction, and cognitive flexibility (or set-shifting). Suitable for individuals between the ages of 11 and 74, it takes 5 to 12 minutes to complete. Scores are quickly calculated and converted to T-scores and percentile ranks.

Reliability of scores for each individual trail is high and the composite score has a reliability coefficient of .90 or higher at all ages. The CTMT is extremely sensitive to neurological insult, disease, injury, or dysfunction, including the subtle neuropsychological dysfunction often present in individuals with learning disabilities. The Examiner's Manual includes discussion of the test's theoretical and researched-based foundation, administration and scoring procedures, and more extensive reliability and validity data.
