| Annotation | Bilateral symmetry is where one half of a pattern is a mirror reflection of the other half. In this Canadian study, the authors tested symmetry detection in different age groups: 10 young adults (aged 19-39); 10 middle-aged (40-60); 8 young-old (61-70); and 9 old-old (71-80). The aim was to determine whether performance of this intermediate-level visual task is affected by normal, non-pathological ageing. Results were analysed with respect to age group and symmetry (vertical, horizontal, and 45 degree oblique). There was a vertical symmetry advantage for all participants, where sensitivity was highest for vertical symmetry, and then the oblique symmetry. Sensitivity to symmetry did not differ for the two younger age groups, but declined significantly for the 61-70 group, and again for the oldest old group. 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. (RH). |
