Distributions of the motion coherence thresholds estimated for full-field translational (red), radial (green), and rotational (blue) optic flow patterns, for the younger (age: 18–30, n = 42, light colors) and older (age: 70–90, n = 42, dark colors) adults groups. Black dots represent group-level means. Error bars represent the associated 95 percent confidence intervals. Horizontal colored lines represent group-level medians. Circles provide the individual data points of the distributions. Note that they were slightly offset horizontally to improve their visibility. Stars indicate significantly different distributions (***p < 0.001).
