Subject: temporal processing From: James Heron <J.Heron1(at)BRADFORD.AC.UK> Date: Tue, 11 Feb 2003 17:09:45 +0000I am a post-grad researcher working in the field of crossmodal interactions. Our lab is on reasonably sure ground with visual stimuli but a bit more ropey when it comes to the auditory stimuli... I have been searching for literature on the effects of the temporal structure of aduitory stimuli (gaussian white noise in our case) on temporal localization. It seems intuitive that if a sound stimuli's amplitude rises and falls in a gaussian envelope then increasing sigma (but keeping peak amplitude constant) would reduce the slaience of the peak (increasing the temporal spread) and make it harder to position in time. All the literature I can find seems to be on duration discrimination/gap detection rather than say, a temporal bisection paradigm. If anyone knows of any work in this area references would be greatly appreciated. I appreciate this is the type of email that might draw a "go find a library" type response but so far the library/ISI has let me down. I can't believe this hasn't been done before and it sound very basic.
