We experience the world through our senses, a constant torrent of sights, sounds, smells, and more. Our brains take these signals and process them, giving rise to our individual perceptions of the world. But sometimes our senses play tricks on us, notably in the case of perceptual illusions. Now, Caltech researchers have developed two new illusions that reveal how the senses can influence each other -- in particular, how sound can give rise to visual illusions. These illusions occur so quickly that they illustrate a phenomenon called postdiction (as opposed to prediction) in which a stimulus that occurs later can retroactively affect our perceptions of an earlier event. The Caltech work is among the first to show this kind of time-traveling illusion across multiple senses. [1]
Seeing what is not there. Because we heard something. Remembering of what was not there. Because we saw something. Living on what is not here. Because we die someday.
Fleeting moments. Ghostly presences.
Dancing on the border of existence.
Lift the veil of time.
And you will see.
They are all standing…
