Auditory tactile synesthesia test12/4/2023 That movie just happens to be quite "noisy" to the synesthetes and was a great screening tool. Having that specific example made it easy to find more people. "I queried a few hundred people and three more individuals turned up," she says. Intrigued, Saenz began to look for other individuals with the same ability, using the original movie seen by the student as a test. Out of the blue, one of the students asked, "Does anyone else hear something when you look at that?" After talking to him further, I realized that his experience had all the characteristics of a synesthesia: an automatic sensory cross-activation that he had experienced all of his life," says Saenz.Ī search of the synesthesia literature revealed that auditory synesthesia-of any kind-had never been reported. "As part of the experiment, a moving display was running on my computer screen with dots rapidly expanding out, somewhat like the opening scene of Star Wars. "While I was running an experiment at the Caltech Brain Imaging Center, a group of students happened to pass by on a tour, and I volunteered to explain what I was doing," explains Saenz, who, along with Christof Koch, the Lois and Victor Troendle Professor of Cognitive and Behavioral Biology at Caltech and professor of computation and neural systems, reports the finding in the August 5 issue of the journal Current Biology. Saenz has to say about how it was discovered. To describe it, it's funner to read what Dr. Now two researchers at Caltech, Melissa Saenz (Who I know! I know someone who discovered something really cool!) and Christof Koch, have identified a new form of synesthesia, auditory synesthesia. For example, grapheme-color synesthesia is where numbers or letters appear to those observing to be shaded or tinged with different colors. Synesthesia, you probably know, is an effect wherein the stimulation of one sense causes automatic sensations in another sense. A very cool discovery out of Caltech: auditory synesthesia.
