Subject: Re: auditory training for the blind From: John Neuhoff <jneuhoff(at)WOOSTER.EDU> Date: Tue, 31 May 2005 21:36:13 -0400 http://www.intellireach.comThere has been some work on echolocation. The basic problem for mobility trainers seems to be that there are huge individual differences in the ability to echolocate. Some people do it amazingly well, (one case study examined the ability of a blind 11-year-old boy to ride a bicycle while avoiding obstacles (McCarty & Worchel, 1954)) .Others never really get it even with massive amount of training. It's also been quite difficult to find a predictor of echolocation performance. The experimental work began in the 1940's with several very thoroguh experiments by Dallenbach & colleagues. Larry Rosenblum and Dan Ashmead have done some work recently in this area. For reviews see: Neuhoff, J. G. (2004). Auditory motion and localization. In J.G. Neuhoff (Ed.) Ecological Psychoacoustics.
