It has been proposed that these cultural differences reflect the utilization of different processes, namely holistic processes by Easterners and analytical processes by Westerners. In the face processing literature, eye movement studies have revealed different fixation patterns for Easterners and Westerners that are congruent with a broader spread of attention by Easterners: compared with Westerners, Easterners tend to fixate more toward the center of the face even if they need the information provided by the eyes and mouth. Although this cultural difference could reflect an impact of culture on the visual mechanisms underlying face processing, this interpretation has been questioned by the finding that Easterners and Westerners do not differ on the location of their initial fixations, that is, those that have been shown as being sufficient for face recognition. Because a broader spread of attention is typically linked with the reduced sensitivity to higher spatial frequency, the present study directly compared the spatial frequency tuning of Easterners (Chinese) and Westerners (Canadians) in 2 face recognition tasks (Experiment 1 and 2), along with their general low-level sensitivity to spatial frequencies (Experiment 3). Consistent with our hypothesis, Chinese participants were tuned toward lower spatial frequencies than Canadians participants during the face recognition tasks, despite comparable low-level contrast sensitivity functions.
