1604140155 A Theory on The Vision-based Mechanisms of Subjective Time Within The Context of The Neural and Psychological Models of Time Perception

Temporal processing is crucial for interval, duration and motion discrimination, as well as the ability to order events. Humans process temporal information over a large scale ranging from microseconds to daily circadian rhythms. The basic questions in the time perception literature include whether timing is centralized or distributed in the brain and whether different time scales or modalities (such as sensory or motor) are processed by different neural mechanisms. In this review, focus will be on visual timing in the millisecond range and the underlying temporal mechanisms.The classical model of a supramodal centralised clock, in which scaling between real and apparent time is accomplished by a change in the arousal level, has been challenged by our evidence, following Johnston et al. (2006), that the apparent duration can be manipulated in a local region of visual field by adaptation to motion or flicker and that the effects of temporal frequency adaptation on perceived duration and perceived temporal frequency are dissociable. The relationship between time, motion and space supports the idea that time is an attribute of a visual stimulus like any other low level features such as color or motion, which we suggest may imply a time pathway in the brain.
