The Trail Making Test (TMT) is a ubiquitous neuropsychological test used to assess cognitive functioning across a breadth of cognitive domains (visual attention1, 2, speed of processing3, mental flexibility1, executive function4 and motor skills3, 5), and originated as a screening tool used by clinicians to differentiate between healthy and cognitively impaired patients6.


The TMT is divided into two path tracing tasks where the participant connects a series of nodes in their correct ascending order as quickly as possible. Task A (TMT A) consists of 25 nodes with increasing integers only, while task B (TMT B) alternates between ascending integers and letters.
