Dear list, Many thanks to all who replied to my query regarding JND for tactile frequency. A summary of responses is below. Ani Patel -------------------------------------------------------------------------------------------------------------------------------- Original query (Oct 23, 2014), from Aniruddh Patel (a.patel@xxxxxxxxx) -------------------------- Can anyone point me to papers which quantify the JND for frequency of silent vibrotactile stimulation? Ideally the data would show JND as a function of frequency over a range of tactile stimulation frequencies. Responses: From Sebastian Merchel
sebastian.merchel@xxxxxxxxxxxxx ------------------------------------------ You can find a review of tactile JNDFs at various body sites (e.g., finger, forearm, whole body) in the following paper: I just uploaded my PhD here: http://www.sebastianmerchel.de/publications.html (first publication from top). It contains a chapter with an extensive
comparison between the auditory and tactile modality. From Charlotte Reed cmreed@xxxxxxx ------------------------------------------------------------ Attached is a pdf that contains a relevant plot on this topic, taken from [page 3 and 4 of a] chapter in a book called “Tactile Aids for the Hearing Impaired.” Edited by I. R. Summers, Whurr Publishers, London, 1992. The chapter was written
by R. T. Verrillo and G. A. Gescheider and is Chapter 1, Perception via the sense of touch. The most relevant article to your inquiry is that of Goff (1967) for sinewave stimulation presented to the finger. That reference is Goff (1967).

The defining textbook answering all your questions (and several more) is the "Handbook of Human Vibration" by my estimated colleague Mike Griffin. http://books.google.co.uk/books/about/Handbook_of_Human_Vibration.html?id=tBaCHObL-XQC&redir_esc=y The correct answer to your question (frequency jnd) depends on several factors (frequency, amplitude, which part of the body you are measuring, which probe, whole body vibration vs fingertip, sitting, standing, lying, etc) From Brian FG Katz brian.katz@xxxxxxxx ------------------------------------------------------------------ We have done some recent studies in tactile sensitivity.
