I'm doing a preliminary research on auditory sensory memory, especially differences due to distictive neural pathways as compared to the olfactory sense neural pathway.

As you know, some of the fundamental psychophysical testing procedures used in auditory testing today have been originally tested and honed for/with the olfactory senses (see for example: ' Sensory Evaluation Techniques').

However, the current neurological research shows a distinct pathway for smell/taste as compared to hearing. The coupling with sight and hearing appears to be more tighter than with the olfactory senses.

I would be interested in any tips for references from the fields of neurology, psychophysics or psychoacoustics that deal with these issues and try to address these in the test methodologies used currently for auditory testing.

As a teaser, I'll point you to an interesting MMN research article that suggests that guided attention can enhance auditory perception, but has no measurable effect on the long term auditory memory as currently tested for single stimulus detection tasks. I think this poses interesting questions for some of the testing auditory methodologies used, especially considering the time intervals, and affirmation of correct answers in auditory discrimination tests. There are other similarly interesting research articles, mainly from the field of neurology.

Does Auditory memory depend on Attention?, L.Demany, S. Clément, C. Semal. Journal of the Acoustical Society of America, 109, 686-700. 2001

It depends. If your ability to hear differences diminishes as you do more repetitions, is because you or your auditory system gets tired. In my experience, when that happens, if I rest a little bit, I can detect differences again. In my experience, it also depends on how tired I (or my auditory system) is on that moment/day. Being stressed doesn't usually help, either.

Anyway, I think there's people here who has more experience in ABXing and could give their experience on these matters.
