Table 3.
Detailed list of all standard deviations (SDs) in the saccade parameters, both between subjects (interindividual) and within subjects (intra-individual)
| Eye Movement Parameter | Interindividual SD | Intra-Individual SD | ||
|---|---|---|---|---|
| ELII | ESC | ELII | ESC | |
| Saccade amplitude | 0.40° | 1.34° | 0.89° | 1.13° |
| Saccade mean velocity | 18.27°/s | 30.56°/s | 33.82°/s | 37.74°/s |
| Saccade peak velocity | 35.37°/s | 57.33°/s | 55.44°/s | 58.17°/s |
| Absolute fixation error | 0.33° | 1.20° | 0.24° | 0.31° |
| Smooth-pursuit gain | 0.07 | 0.20 | 0.07 | 0.19 |
Although there were huge differences in the interindividual SDs between the two systems, these differences were markedly smaller for the intra-individual SDs
