Instead we allowed the listener in a 2AFC task to respond "uncertain" when she couldn't be sure. Then we manipulated their criteria for using the uncertain response, through instructions, causing them to use it from 0-75% of the time. Treating the data as though from a 3 pt rating scale, d' was essentially independent of their use of the uncertain response. Watson, C.S., Kellogg, S.C., Kawanishi, D.T. and Lucas, P.A. (1973). The uncertain response in detection-oriented psychophysics. J. Exp. Psychol., 99, 180 185.

If I remember correctly this has been quite enthusiastically studied in the 70ies, in terms of implicit and explicit knowledge.

In the hands of Kawahara-san, STRAIGHT produces astoundingly good morphing.

So far I've found the following papers containing such duration dependencies: Hanna, Thomas E. "Discrimination of reproducible noise as a function of bandwidth and duration" Perception and Psychophysics, 1984, 36 (5), p. 409-416 Heller, Laurie M and Trahiotis, Constantine "The discrimination of samples of noise in monotic, diotic, and dichotic conditions" Journal of the Acoustical Society of America, 1995, 97 (6), p. 3775-3781 Fallon, Suzan M. "Discriminability of bursts of reproducible noise" Dissertation - Indiana University, 1998 All publications with noiselike stimuli, and especially Gaussian noise, that measured discrimination ability as a function of time are very much appreciated.
