Summed magnitude values of horizontal and vertical contour projections compared with oblique angles in the four different settings analyzed
| Type of scene | Orientation | Mean ± SEM, ×1000 | P value |
|---|---|---|---|
| Indoor | Cardinal | 33.6 ± 1.70 | <0.0001 |
| Oblique | 15.5 ± 7.59 | ||
| Total | 49.16 ± 1.23 | ||
| Outdoor | Cardinal | 46.2 ± 1.95 | <0.0001 |
| Oblique | 31.2 ± 1.55 | ||
| Total | 77.49 ± 1.75 | ||
| Natural | Cardinal | 60.7 ± 1.21 | <0.0001 |
| Oblique | 53.6 ± 1.03 | ||
| Total | 114.41 ± 1.1 |
The statistical significance of the differences between the representations of contours in the cardinal axes vs. oblique angles is based on paired t tests.
