Subject: Re: Perception as memory From: "Richard M.

He interpreted his observations as =20 representing both a refinement of memory and an improvement of =20 perceptual ability. He asked whether listeners would be able to do =20 this with other sounds. If Kevin means to ask if listeners can use memory to separate a sound =20= into components, the answer is yes. For example, if listeners are =20 presented with a 1/3-octave band of noise for a few seconds followed =20 by broadband noise they can =93hear=94 the narrow band noise continue as = a =20 component for tens of seconds. A linguistic example of the use of =20 long-established memory to =93hear out=94 sounds in noise is afforded by = =20 phonemic restoration in which listeners =93perceive=94 missing phonemes = or =20 even entire syllables (e.g., the =93gis=94 in legislatures) that have = been =20 replaced by noise. Our lab has studied the use of memory to =93hear=94 =20= contextually appropriate sounds by segregating portions of another =20 sound using the rubric =93auditory induction.=94 Dick =93Without the senses there is no memory, and without memory there is no = =20 mind.=94 -Voltaire in his short essay =93Memory=92s Adventure=94 Richard M.
