Abstract
Accurate time perception is crucial in peripheral vision especially for the spatial perception during actions. To investigate the dynamics of time perception in peripheral vision, parvocellular-biased and magnocellular-biased flashes were presented at different eccentricities (0-48 degrees ) in an interflash interval discrimination task. Results showed an increase in time compression with eccentricity for both stimuli (magnocellular-biased and parvocellular-biased flashes). Nevertheless, when stimulus visibility was 'equalized' across the visual field, the increase in time compression was only found for magnocellular-biased stimuli. Thus, we suggest that the magnocellular pathway accounts for time underestimation. Moreover, its increase with eccentricity could be an inherent property of the magnocellular system more than a result of a decrease in stimulus visibility.
