Re: perecption of durational variability

Title: Re: perecption of durational variability
Dear Volker:

I believe you are referring to the finding that Weber's law, which holds approximately (though not precisely) for duration discrimination, breaks down at short durations, typically between 200 and 300 ms. A good review of findings on this topic is provided in

Friberg, A., & Sundberg, J. (1995). Time discrimination in a monotonic, isochronous sequence. Journal of the Acoustical Society of America, 98, 2524-2531.


Dear list-members,

I am looking for research on a very specific topic:

I seem to remember that there is evidence for the hypothesis that listeners' ability to discriminate between the duration of two stimuli decreases with proportionally decreasing overall duration of the stimuli (i.e. increasing rate of the stimuli).

I have spent hours and hours today looking for this and found millions of influential factors on the perception of duration but not this. Does anybody have an idea where to look for?

Thanks in advance and best wishes,
