Presaccadic attention effects in all tested eccentricities. (A) Target contrast as a function of cue-target relation for each stimulus eccentricity: Towards and Away conditions are shown in red and gray, respectively. The black dot on each boxplot represents the median and the whiskers represent the upper and lower value. The colored clouds represent the density distribution given by the dots, which represent subjects’ performance individually. (B) Presaccadic perceptual gain (Towards-Away) across all eccentricities. Colored clouds represent the density distribution given by the dots separately for each eccentricity. The Bayes factor (BF₀₁ = 22.691) indicates strong evidence in favor of the null hypothesis, suggesting no meaningful effect of saccade amplitude on contrast sensitivity.
