Trail Making Test (TMT; Reitan & Wolfson, 1986) A brief paper-and-pencil test involving numeric sequencing (Trail A) followed by alpha-numeric sequencing (Trail B) in original form. The Trail B was modified by using Chinese phonic symbols to substitute for English alphabet when applying to Chinese participants. Completed time and off-target errors on the tasks are oriented to the attentional components of sensory selection, response selection, and capacity/focus.
