Ascending lingual vibrotactile thresholds at 250 Hz were obtained for four groups of normal-speaking adult subjects. Stimulus durations were varied for each respective group. Threshold values plotted as a function of stimulus duration indicated a temporal summation function occurring up to 200 msec. Findings are discussed in terms of underlying peripheral receptors and some implications for using summation measures as a basis for identifying oral sensory disorders.
