Last week, I posted about auditory illusions featured on New Scientist's Web site. In the discussion following the post, several readers commented on the pioneering work in this area by UC San Diego psychology professor Diana Deutsch. She's been researching auditory illusions for decades and even curated two CDs of examples, "Musical Illusions and Paradoxes" and "Phantom Words and Other Curiosities." Deutsch's research page provides samples of some of those illusions. From her site:
Here we describe and illustrate some of Deutsch’s musical illusions and paradoxes. They show that people can differ strikingly in the way they hear very simple musical patterns. These disagreements do not reflect variations in musical ability or training. Even the finest musicians, on listening to the stereo illusions described here, may disagree completely as to whether a high tone is being played to their right ear or to their left. And the most expert musicians, on listening to the tritone paradox, can engage in long arguments as to whether a pattern of only two tones is moving up or down in pitch.
How do we explain these striking perceptual discrepancies? In the case of the stereo illusions, disagreements tend to arise between righthanders and lefthanders, indicating that they reflect variations in brain organization. In contrast, the way the tritone paradox is perceived varies with the geographical region in which listener grew up, so differences here are related to the languages or dialects to which people are exposed.
The illusions and paradoxes described here lead us to wonder what other curiosities of music perception might exist that have not yet been discovered. But using the principles that generate these illusions, we can now produce music that sounds radically different from one listener to another, and even from one audience to another.
This gadget does exactly as promised: it looks like a thumbdrive (sort of) and fries the circuitry of any computer it’s plugged into. It’s made from camera flash parts, is charged with a standard AA battery, and delivers a 300V zap of DC destruction to the port for all your USB-murdering needs. Note that this […]
The Cobham catalog, exposed by The Intercept, features countless pages of surveillance gadgets sold to U.S. police to spy on American citizens: tiny black boxes with a big interest in you. In the creepily bland feature lists and nerdy product names is a whisper of a dark future; perhaps darker than anyone can imagine.
This image depicts the most commonly-found stylesheet colors on the web’s top sites—Paul Hebert did an amazing amount of analysis and this is just one of the intriguing visualizations he came up with. Most of these are obvious staples, especially HTML red and blue, though it’s interesting how far the blue “cluster” is from the […]
