Moving Through Time
Thinking of the past or future causes us to sway backward or forward
Although we can't technically travel through time (yet), when we think of the past or the future we engage in a sort of mental time travel. This uniquely human ability to psychologically travel through time arguably sets us apart from other species. Researchers have recently looked at how mental time travel is represented in the sensorimotor systems that regulate human movement. It turns out our perceptions of space and time are tightly coupled.
These findings reported online in Psychological Science, a journal of the Association for Psychological Science, suggest that chronesthesia may be grounded in processes that link spatial and temporal metaphors (e.g., future= forward, past= backward) to our systems of perception and action. "The embodiment of time and space yields an overt behavioral marker of an otherwise invisible mental operation," explains Miles and colleagues.
