Scientists Create Touch-based Illusion: Mind Trick Yields New Insights On Perception

Anyone who has seen an optical illusion can recall the quirky moment when you realize that the image being perceived is different from objective reality. Now, a team of scientists from MIT, Harvard and McGill has designed a new illusion involving the sense of touch, which is helping to glean new insights into perception and how different senses--such as touch and sight--work together. Ambiguous visual images are fascinating because it is often difficult to imagine seeing them any other way--until something flips within the brain and the alternative perception is revealed. This phenomenon, known as perceptual rivalry, is of great interest to neuroscience.  ... we wanted to see whether similar illusions can occur in the tactile domain.  - read what they found on sciencedaily
