Saccadic curvature

(A and B) Curvature time course as a function of DSOA (SMART analysis⁵⁹) for optimal (red) versus non-optimal (pink) features (A), and for high-luminance (blue) versus low-luminance (cyan) features (B). Shaded areas around the curves: 95% confidence interval. Colorful shaded rectangles: time intervals with significantly different curvature induced by high-salient versus low-salient distractors (p < 0.01; light-red: optimal versus non-optimal features; light-blue: high versus low-luminance features). Solid parts of lines: time windows (ms) with curvature significantly different from zero (p < 0.01; baseline versus non-optimal features: [−336, −247] ms, [−229, −169] ms, [−146, −93] ms; baseline versus optimal features: [−302, −176] ms, [−145, −92] ms, [−72, −43] ms; baseline versus low-luminance features: [−340, −336] ms, [−285, −248] ms, [−214, −166] ms, [−134, −102] ms; baseline versus high-luminance features: [−340, −33] ms, [−298, −174] ms, [−147, −90] ms, [−70, −57] ms). Dashed parts of lines: curvature compatible with zero.

(C) Experimental condition - Average trajectories. Left panel: saccades with DSOA between −267 ms and −204 ms showing deviation away from the distractor; right panel: saccades with DSOA between −111 ms and −102 ms showing deviation toward the distractor.

(D) Luminance-control condition - Average trajectories. Left panel: saccades with DSOA between −248 ms and −217 ms showing deviation away from the distractor; right panel: saccades with DSOA between −154 ms and −125 ms showing deviation toward the distractor. Errors are SE across participants.
