“…This finding appears to conflict with the data of Verrillo (1966Verrillo ( , 1968 but is consistent with some of the data of Fucci and his colleagues (e.g., Fucci & Petrosino, 1982;Hall, Fucci, & Arnst, 1972;Telage et al, 1972). One interesting feature of Verrillo's (1968) lingual data, however, is that the presence of a surround did not significantly decrease the sensitivity to high-frequency vibration.…”

Two experiments were carried out to investigate the effect of cooling on the sensitivity of the tongue to vibration. In the first experiment the temperature of the tongue was held at 36 0 , 28 0 , or 20 0 C while the thresholds for detecting 30-and 250-Hz vibrations were measured using a twoalternative forced-choice paradigm. Cooling the tongue to 20 0 reduced the sensitivity to 250-Hz vibration but did not disturb the sensitivity to 30-Hz vibration. The second experiment established that cooling continued to reduce the sensitivity to the 250-Hz stimulus even when intensity levels were raised to 30 dB SL. The results are discussed in relation to (1) which types of mechanoreceptors mediate the perception of vibration on the dorsal surface of the tongue, (2) the effect of a rigid surround on lingual vibrotactile sensitivity, and (3)the possible impact of temperature on perception of the mechanical characteristics of foods.Tactile information from the tongue is important for both the manipulation and the sensory assessment of ingested foods. In recognition of this fact and because of the presumed importance of tactile feedback from the tongue during speech production, a relatively large literature has developed on lingual mechanical sensitivity.

“…The initial focus concerned investigating psychophysical parameters involved in presenting the vibratory signal to the midline of the anterior lingual surface. Hall, Fucci, and Arnst (1972) found no differences between data obtained with either the method of limits or the method of adjustment. Differences between ascending and descending thresholds obtained with pulsed stimulation were also found to be insignificant.…”

Ascending lingual vibrotactile thresholds were obtained from the anterior midline of the tongue for 110 normal speaking adult Ss at 200 and 400 Hz. Two threshold criteria, one test trial and the median of three successive trials, were used at each frequency . The t test comparisons between testing modes showed no significant differences. Correlations between testing modes were high and suggested direct rank orderings of threshold values. These findings were discussed in terms of possible advantages of using the simpler procedure as a more practical approach for measuring oral tactile sensation with children.

“…Table 1 shows the vibrotactile thresholds in microns for normal-speaking and sibilant-defective children. The differential response to frequency was significant and conformed to earlier studies of adults (Fucci, Hall, & Arnst, 1972). A t each frequency, a t rest was performed between groups.…”

“…The stimi~lus and nieasurement units were essentially identical to those employed by Fucci and colleagiies (1972;Hall, Fucci, & Arnst, 1972;Fucci, Hall, & Weiner, 1971). The stimulus unit contained a sine wave generator, frequency counter, electronic switch, attenuator, amplifier, and shaker.…”

Vibrotactile Thresholds and Oral Stereognosis in Children

This investigation was designed to compare oral vibrotactile thresholds and oral form identification measurements on 10 normal-speaking children and 10 children with sibilant articulation defects. The two measures employed included the NIDR 20 oral stereognostic forms and tongue-tip vibrotactile thresholds at 50, 100, 200, 300, and 400 Hz. The results of oral stereognostic testing were not useful in predicting sensitivity to lingual vibrotactile stimuli for either normal-speaking or articulatory-defective Ss. Children with normal and defective articulation did not differ in their responses either to oral stereognosis or to vibrotactile stimulation. There were differences in vibrotactile thresholds at different frequencies for both groups.
