Effects of Attention upon sensitivity as a Function of Eccentricity. (A) Output of linear models for the data of Experiment 1 quantifying the region by ring effects. Separate models of the same form were computed for the white and yellow stimuli. The symbol face colors indicate the stimulus color (legend below). “+” Indicate significant differences at p < 0.05 for the linear models. (B) Output of a linear mixed-effects models for the white and yellow stimuli of Experiment 2. ‘*’ Indicate significance for the mixed-effects models. (C) Mixed effects model outputs for the Blue and Yellow stimuli of Experiment 3. The ordinate ranges are the same for B and C. The cyan line in B gives the simple model: White = Yellow + Blue, where the Yellow data are those of (B) (for 23 subjects) and the Blue data are from (C). The cyan line is a reasonable match for the white data of (B).
