The effect of subjective area size on time perception(Summary of Awarded Presentations at the 24th Annual Meeting)

抄録

The perceived duration of a stimulus is increased or decreased when its physical attributes, such as area size, differ from those of a comparison stimulus. We measured the perceived duration of a visual object with an invariant physical size, but whose apparent area size was altered by the Ebbinghaus illusion: a central circle surrounded by larger inducers appears smaller than a central circle of the same size surrounded by smaller inducers. The results showed that the perceived duration of apparently large circles was longer than that of apparently small circles, even though the actual area size remained invariant. We conclude that information about time perception is embedded in later visual processing systems.
