The CTMT evaluates aspects of executive function with five visual search and sequencing tasks dependent on attention, concentration, resistance to distraction, and cognitive flexibility (set shifting). It can be used by neuropsychologists, occupational therapists, speech-language professionals, physical therapists, and clinical, school, and pediatric psychologists to evaluate frontal-lobe deficits and impairment of psychomotor speed, visual search and sequencing, attention, and set shifting. The tasks require numbers or letters to be connected in a specified sequence; scores reflect the time taken for completion. The test was standardized on a nationally representative sample of 1,664 persons. Reliability coefficients are high (0.90 or higher) for both individual subtests and the composite score.
Administration and Scoring
The CTMT is individually administered, and typically can be completed and scored in less than 20 minutes. Results are reported as T-scores and percentile ranks.
