Dear Al and List, Repeating a recording of any clearly pronounced word produces illusory word= s or syllables that has been called the "verbal transformation effect." Go= ogling this term will produce a list of articles dealing with the effect, i= ncluding the link to "Warren Perception Lab - Auditory Demonstrations," whi= ch produces examples of both repeating diotic and dichotic stimuli. Incidentally, making the stimulus indistinct by the addition of noise redu= ces the rate at which illusory changes occur.
