Figure 11.

Correlation between the EEI of contrast sensitivity and (A) orientation gain (peak amplitude yielded the same result), (B) orientation bandwidth, (C) induced noise, and (D) constant noise. A positive EEI indicates the fovea being higher than the perifovea and vice versa. Greater positive/negative EEI indicates a larger fovea–perifovea difference. Markers are the median of EEI for each individual observer. The diagonal black line is the linear regression line. **p < 0.01, *p < 0.05, n.s., p > 0.1.
