Abstract The two variants of the Trail Making Test (TMT) are the vertical layout TMT, which has been reported to be a part of the Halstead-Reitan Battery and horizontal layout TMT created by Kashima et al. However, the results of the two vary widely and no detailed discussion has been offered for the variations. For this study, the two kinds of TMT were conducted with healthy young subjects, by comparing the time each one of them required to complete the tests. The results revealed that the time required by the horizontal layout TMT was extended relative to the vertical layout TMT, with no difference in the time required between Part A and Part B. The time required for Part B was extended on the vertical layout TMT. While the investigation was conducted by dividing the results by the length of the line drawn until the completion of the TMT, the time required was still extended for the horizontal layout TMT relative to the vertical layout TMT. The line drawn on the vertical layout TMT followed a circular trajectory; hence, it seems that the fact that the line on the horizontal layout TMT overlapped randomly suggests that the visual search became more difficult, leading to an extension of the time required.
