Purpose: : The aim of the study was to determine whether the relative contribution of low vs high spatial frequencies in natural scene perception depended on subjects’ age.

Methods: : Subjects’ instructions were to name verbally the category of the scene displayed. Four scene categories were considered: indoor, landscape, city and highway. Four different test images were generated for each scene category: non-filtered, high-pass filtered, low-pass filtered and hybrid images. Hybrid images were constituted by the low spatial frequencies of one scene and the high spatial frequencies of another scene (Schyns, Oliva, 1994, Psychological Science, 195-200). Images were displayed for 30 ms. Thirty two young adults (aged between 22 and 45; Group1) and 31 adults (aged between 45 and 70; Group2) participated in the study. The 24 test images were displayed 3 times for each subject.

Results: : Proportions of correct responses of both groups were compared. Results showed that Group1 and Group2 performed at the same level for non-filtered, high-pass filtered and low-pass filtered images. However, when low and high spatial frequencies were displayed simultaneously in hybrid images, Group2 exhibited a preference for low spatial frequencies significantly higher than Group1 (p=0.0346).
