Ok, we absolutely need to chat ... I'll email you off list.
 
And no, I have no formal training in psychoacoustics at all, but I enjoy reading in that field, and I hope to incorporate it into my
own research which is currently focused more on the haptics side of the house, purely as a function of funding, which I'm sure you
understand, *smile*. 

I'm currently working on my PhD in computer science.

Take care,
Sina

Sina,
  You are right up, or at least very close to my alley:). In fact, I am reading a paper right now on fusion of auditory stimuli,
somewhat in line with what you were noting about influences of sound on prior information/following, masking, and the like. I am a
psycholinguist in training, and love this stuff too. Psychoacoustics is incredibly fascinating as is spoken word processing, my more
specific area. I hope to do some work in the future with neuropsych (e.g., ERP or F-MRI). We have a couple of labs for doing both
though my work currently does not use these methods.

  Are you a psycholinguist or psychoacoustician...? I would love to chat.
Many thanks,
Christine

>> 2. Editing of graph data through the data table in the application.
>> 3. Sonification of the entire graph.

>> 5. Speech production of different points in the graph.
>> 6. Navigation from point to point via the use of the arrow keys.
