Title
Effects of Object Size and Viewing Distance on Duration Perception
 
Abstract
Although accurate time perception is necessary to properly respond to the environment, it was discovered that non-temporal features also affect time perception. Previous studies have identified various factors that affect time perception, but there was no attempt to directly investigate the possible effects of the distance between participants and the stimuli on time perception. The current study examined the effects of viewing distance on time perception, by considering the retinal, physical, and perceived size of the stimuli. The viewing distance had no effect when either the physical size or the perceived size of the stimulus was the same. Viewing distance was found only to have an effect when the retinal size of the stimulus was the same. This effect might be a size effect rather than a distance effect because as the viewing distance increases the size should also increase to maintain the retinal size. These results imply that temporal perceptual constancy is preserved irrespective of the viewing distance, when distance information is not limited.
