Re: Integration of ITD information

Dear list,
Is there any evidence for integration of interaural time difference
(ITD) information across frequency channels in ITD detection /
discrimination tasks? More specifically, are ITD JNDs lower for a
broadband stimulus compared to any narrowband stimulus within the
spectral range covered by the broadband stimulus?
Of course, I assume that the overall intensity is held constant.
I would appreciate any hint,
With best regards,
Bernhard Laback
That is an interesting question. I would recommend the following
papers; Anyone know of any other relevant ones?

Title: THE COMBINATION OF INTERAURAL INFORMATION ACROSS FREQUENCIES -
LATERALIZATION ON THE BASIS OF INTERAURAL DELAY
