Overview of the maximum improvement and optimal noise levels for the different experiments and different analysis
Experiment | Initial analysis | Control analysis | ||
---|---|---|---|---|
Optimal noise level mode | Maximum improvement (%, mean ± SE) | Optimal noise level mode | Maximum improvement (%, mean ± SE) | |
Subthreshold | ||||
Visual–noise | 60% of noise threshold | 15.67 ± 2.69 | 60% of noise threshold | 12.04 ± 2.83 |
tRNS–noise | 1 mA | 14.38 ± 2.41 | 1 mA | 11.07 ± 2.27 |
tRNS–control | 0 mA | 5 ± 2.01 | 0 mA | 2.45 ± 1.65 |
Suprathreshold | ||||
Visual–noise | 0% of noise threshold | 5.53 ± 1.78 | 30% of noise threshold | 3.71 ± 1.55 |
tRNS–noise | 0 mA | 7.34 ± 1.47 | 0 mA | 4.87 ± 1.18 |
tRNS–control | 1.5 mA | 4.44 ± 1.54 | 0 mA | 1.48 ± 0.89 |
The results of our additional analysis confirmed the results of our optimal noise level analysis even though the performance improvement observed for the optimal noise level is, as expected, smaller in our additional analysis.
