Fig. 7. Removing the textured background does not affect saccade amplitude. (A) Plots of approach angle versus saccade angle (see Fig. 3) within a uniform background (black symbols). For comparison, the distributions of saccades in a textured background are replotted from Fig. 3 (gray symbols). In both cases, there are two clusters of saccades centered at ±90°. The r² values from regression lines fitted to each cluster were again small (r²<0.05, P<0.02 for both). (B) Probabilities of saccading left (blue) and right (red) within uniform and textured backgrounds. Probability distributions were found as described in Fig. 3. The probability of saccading in each direction was similar for flight within the uniform (solid lines) and textured (dashed lines) backgrounds.
