Trail Making Test J Lite 1.3

The Trail Making Test (TMT) serves as a valuable neuropsychological assessment tool that evaluates visual attention and the capacity for task switching.

In Part A of the test, the participant is required to connect the numbers 1 through 25 in ascending order as swiftly as possible.

Part B introduces an additional layer of complexity, requiring the participant to alternate between the numbers 1 to 13 and the letters A to L in ascending order (i.e., 1-A-2-B-3-C, etc.).

The results from both Part A and Part B are quantified by measuring the total time taken to complete each task, along with the number of errors made. Notably, higher scores indicate greater cognitive impairment.

A general benchmark for performance is as follows:

• Part A: Completion time for most participants is around 90 seconds.
• Part B: Completion time for most participants is approximately 3 minutes.
