The Trails-X is an innovative take on the traditional trail-making task that includes additional executive function demands by requiring examinees to connect circles of alternating colors with no designated start or end point. Individually administered, the Trails-X offers nine trails that assess adaptive planning, coupled with psychomotor speed, cognitive flexibility, impulse control, flexible attention, and the ability to adapt to novel or changing situations. The examinee is asked to draw straight, nonoverlapping lines connecting circles of alternating colors and continue until all circles are connected. Individuals must work carefully to avoid crossing lines or being forced to discontinue before the task is complete. Examinees must plan their path and adapt while working as quickly as possible.
• Removes the requirement of numeracy and literacy as there is no need to be able to recognize letters or numbers, which makes this task language free and more culturally fair.
• Circles are yellow and blue, as they are colors that are least likely to be problematic for individuals who are colorblind.
