双侧对称的显著性随着对称轴的方向而变化。垂直对称是最突出的，其次是水平和倾斜方向。我们测试了不同年龄组的对称性检测，以确定这种中等水平的视觉任务的性能是否受到正常的，非病理性的老化。我们测试了40名参与者，并分析了年龄组和对称方向（垂直，水平和45度倾斜）的结果。所有参与者都有垂直对称检测优势，其中垂直对称的灵敏度最高，其次是水平对称，然后是斜对称。两个较年轻的年龄组（19-39岁和40-60岁）对对称性的敏感性没有差异，但61-70岁的年龄组显着下降，71-80岁的年龄组再次下降。这种与年龄相关的对称性敏感性差异并没有反映在偏倚的测量中，其中没有作为年龄函数的差异。
The salience of bilateral symmetry varies as a function of the orientation of the symmetry axis. Vertical symmetry is most salient, followed by horizontal and then oblique orientations. We tested symmetry detection in different age groups to determine whether performance of this intermediate-level visual task is affected by normal, nonpathological aging. We tested forty participants and analyzed the results with respect to age group and symmetry orientation (vertical, horizontal, and 45 degree oblique). There was a vertical symmetry detection advantage for all participants, where sensitivity was highest for vertical symmetry, followed by horizontal symmetry, and then the oblique symmetry. Sensitivity to symmetry did not differ for the two younger age groups (aged 19-39 and 40-60), but declined significantly for the group aged 61-70, and declined again for the oldest group aged 71-80. This age-related difference in sensitivity to symmetry was not reflected in a measure of bias, where there were no differences as a function of age.
