Trail Making Test (TMT)

This is an example of a Trail Making Test (Partington & Leiter, 1949), a computerized measure of working memory capacity. Try to connect the circles as quickly as possible in sequential order. BUT: Switch between numbers and letters (e.g., 1 - A - 2 - B - 3 - C, etc.).


The script requires the javascript library jQuery licensed under the MIT and GPL.


I cannot offer any support for the implementation or adaption of the script.
