Table 2.
Neuropsychological results (number of subjects) and Brunner-Munzel test statistics (max. z, z crit) over various TMT error scores.
| TMT error scores | no errors | 1 error | ≥2 errors | max. z | zcrit |
|---|---|---|---|---|---|
| TMT-A, sequencing errors (type C) | 26 | 2 | 2 | 2.425 | 3.452 |
| TMT-B, total errors | 9 | 8 | 13+ | 3.972∗ | 3.501 |
| TMT-B, shifting errors (type A) | 18 | 9 | 2 | 3.084 | 3.381 |
| TMT-B, shifting errors (type B) | 20 | 6 | 4 | 4.163∗ | 3.285 |
| TMT-B, shifting errors (type A + B) | 16 | 7 | 7 | 3.233∗ | 2.996 |
| TMT-B, sequencing errors (type C) | 28 | 2 | 0 | 3.154 | 3.154 |
| TMT-B, sequencing errors (type D) | 22 | 6 | 2 | 4.250∗ | 3.403 |
| TMT-B, sequencing errors (type C + D) | 20 | 8 | 2 | 3.724∗ | 3.285 |
Note: ∗ p < .05. +All patients who made two or more than two errors of either type on the TMT-B (i.e., TMT-B total errors) had frontal lesions in Stuss et al.'s [24] study.
