The Trail-Making Test (TMT) is a measure of visual scanning, complex attention, psychomotor speed, and mental flexibility. The TMT is an adaptation of John E. Partington's Test of Distributed Attribution, which was originally developed in 1938 to assess intellectual function. It was later renamed Partington's Pathways Test and was used to examine the effects of opiate use on brain function (Partington & Leiter, 1949). Subsequently, it was incorporated into the Army Individual Test Battery in 1944, where it received its current name. It was incorporated into the Halstead-Reitan Neuropsychological Test Battery (HRNB) with minor modifications, and it remains one of the most frequently used neuropsychological tests in research and clinical practice (Rabin, Barr, & Burton, 2005).
