The perception of space and time are generally studied separately and thought of as separate and independent dimensions. However, recent research suggests that these attributes are tightly interlinked: event timing may be modality-specific and tightly linked with space. During saccadic eye movements, time becomes severely compressed, and can even appear to run backwards. Adaptation experiments further suggest that visual events of sub-second duration are timed by neural visual mechanisms with spatially circumscribed receptive fields, anchored in real-world rather than retinal coordinates. All these results sit nicely with recent evidence implicating parietal cortex with coding of both space and sub-second interval timing.
