Behavioral performance during visuo‐spatial attention task
| Efficacious NS stimulation | Nonefficacious NS stimulation | * P value | |
|---|---|---|---|
| Mean (SD) percentage of correct responsesa | |||
| Active task | 93.1 (5.0) | 92.4 (6.8) | n.s. |
| Control task | 99.7 (0.6) | 99.0 (2.5) | n.s. |
| Mean (SD) RTs (ms)b | |||
| Active task | 600.5 (33.2) | 524.9 (121.2) | 0.01 |
| Control task | 455 (30) | 399 (63.8) | 0.01 |
*
Student's t‐test for paired samples. NS, neck suction; RTs, reaction times.
a
No significant difference in task performance was observed by comparing blocks under efficacious (−60 mm Hg) and nonefficacious (−10 mm Hg) neck suction (NS) stimulation regardless of the type of task (active or control).
b
RTs were significantly longer during efficacious as compared to nonefficacious NS simulation in both conditions, active and control task.
