My personal solution to this problem is to misplace the headphones such that only one of them is placed over the ear. The other ear is free, and I get my dinner / hear the cat in the dust bin / ... It is true that this monaural (not binaural but mono) presentation could help for the same reason that Tim assumes to work in the binaural case: placing the image of the transmitted data outside the head. I always thought of it as being a mixture of a) less obstruction of the free ear, b) optimal BMLD situation. It is intruiging to assume it has to do with localisation. It would be nice to have precise data. All could be done with binaural recordings: adding a binaural target to a) true binaural distractor or b) normal "inside the head" stereo recordings. There should be two different tasks: A "perceptual" task, with the subject knowing exactly something is to come and the only task being to detect it correctly, and an "attentional" task with the subject having to spend some effort on the distractor stimulus (counting words would be enough?) and on the other hand react to some key word ("dinner") in the (ongoing but normally irrelevant) target stimulus. I would assume that the effect is mainly an attentional one, but I am not sure. - Christian Kaernbach McGill is running a new version of LISTSERV (1.8d on Windows NT).
