Detailed Description+

Assesses visuomotor processing speed and cognitive flexibility.
Often, the Trail Making Test is used as one of several measures for initial assessment of performance in several areas of brain functioning, including neuropsychological functions (attention, processing speed, visual scanning) and executive functions (working memory, inhibition, cognitive flexibility). While TMT A is associated primarily with basic functions such as visual attention, visual scanning, and processing speed (Bowie & Harvey, 2006), the higher-order executive cognitive functions such as working memory, inhibition, and cognitive flexibility are usually associated with the TMT B (Bowie & Harvey, 2006; Linás-Reglá et al., 2015; Spreen & Strauss, 1998).

Task+

The TMT-S represents a computerized, adapted version of the test which corrects for some of the deficits of its predecessor. In the first section of the test (part A), the task is to click on the numbers 1 to 25, which are spread out on the screen in a pseudo-randomized order, as quickly as possible in ascending order. In the second section of the test (part B), respondents must click on the numbers 1 to 13 and the letters A to L on the screen alternately and in ascending/alphabetical order as quickly as possible.

Scoring+

The TMT-S is scored on the basis of two main variables.

  • The variable Processing speed comprises the sum of the working times for all items in part A, with working time defined as the time between the correct selection of two successive numbers.
  • The variable Cognitive flexibility comprises the sum of the working times for all items in part B, with working time again defined as the time between the correct selection of two successive numbers.

The additional variables Difference B-A and Quotient B/A enable the individual’s cognitive performances to be compared with each other in a more nuanced assessment.
