The psychophysical method of magnitude production was used to obtain suprathreshold sensation magnitude functions at three frequencies (100 Hz, 250 Hz, 400 Hz) from the anterior midline portion of the tongue of 10 adult subjects. Results showed the slopes of the curves generated to be frequency dependent. The shallowest curve was obtained for the frequency of 250 Hz, with somewhat steeper curves being derived for the frequencies of 100 Hz and 400 Hz. An explanation of the frequency effect is attempted in terms of the possible neural receptor units involved in lingual suprathreshold vibrotactile stimulation.
