With regard to whether we can "process" more than one acoustical signal
simultaneously, the discussion should take account of a couple of early
demonstrations that people can listen for more than one frequency at
the same time, as though they were paying attention to two separate
auditory "filters" tuned to attend to each. The relatively small loss
in detectability in such a case corresponds to the added "noise" in the
alternative channel while both are attended. The data are incompatible
with any model involving time-switching between channels: Green, D.M. (1961) JASA , 33 897-903 and Creelman, C.D. (1960) JASA, 32, 805-810. Doug Creelman -- C. Douglas Creelman 416-690-9407 (phone & fax) 9 Fernwood Park Ave. creelman@xxxxxxxxxxxxxxxxx Toronto, ON Canada M4E 3E8 |
