Trail making test
TMT part A (TMT-A) and part B (TMT-B) were performed to assess attention and executive function. Participants were asked to connect the numbers from 1 to 25 in TMT-A and to connect the numbers from 1 to 13 and the 12 Japanese letters alternatively in TMT-B as early as possible. The time taken to perform the test and the number of errors were assessed.
