DIANA DEUTSCH is a professor of psychology at the University of California, San Diego. She is internationally known for the musical illusions and paradoxes that she discovered: octave illusion, the scale illusion, the glissando illusion, the tritone paradox, the cambiata illusion, the phantom words illusion and the speech-to-song illusion, among others. She also explores memory for music, and how we relate the sounds of music and speech to each other. In addition she studies absolute pitch - why some people possess it, and why it is so rare.
