In recent years, there has been an increasing number of studies discussing the fundamental differences in perception between central and peripheral visual fields (form, color, and texture) (Baldwin et al., 2019; Cohen et al., 2020; Cohen et al., 2021). However, the results of prior studies on differences in time perception are contradictory (Long & Beaton, 1981; Kliegl & Huckauf, 2014; Bao et al., 2024). This study examines the differences in duration perception between the central and peripheral visual fields using static Gabors. In the experiment, two Gabor patches (10° of diameters, spatial frequency: 5cpd, 100 % contrast, with a randomized phase) were presented sequentially at two locations: the peripheral (10, 30, 50, 70°) and central (0°) visual field. Two standard stimulus durations (67/250ms) were consistently presented in the periphery, while the duration of the central Gabor was varied at nine steps. Participants were instructed to select which Gabor lasted longer. The results indicated that underestimation of duration occurred in the peripheral visual field. However, no significant differences in duration perception were observed between 10° and 70° for either standard duration. The fact that no significant differences in time perception were found in the 10 to 70° may suggest that time perception is relatively stable across different eccentricities, from the central to the periphery. This indicates that time perception may depend on a higher level of visual information processing stage.
