Trail Making Test

Connect circles in order as fast as you can. Part A: numbers 1–25. Part B: alternate numbers and letters (1→A→2→B→…→13).

Trail Making is a timed visuomotor task. Part A is mostly speed; Part B adds set switching between numbers and letters. The B−A gap is often used as a rough index of switching cost — track it over time, not as a clinical cutoff.
