Oral Perception: II. Mandibular Kinesthesia Normative difference limen (DL) data for mandibular kinesthesia are reported. Following a constant stimuli paradigm, measures of the magnitude of change in mandibular positioning that are necessary for the perception of such changes by 30 normal subjects were determined.

Normative difference limen (DL) data for mandibular kinesthesia are reported. Following a constant stimuli paradigm, measures of the magnitude of change in mandibular positioning that are necessary for the perception of such changes by 30 normal subjects were determined. Results indicate that, for the range of oral apertures studied, the absolute DL values are relatively independent of the degree of mouth opening. This finding is interpreted to indicate that, as the size of the oral aperture increases, proportionately smaller changes in mandibular positioning are required for judgment of differences.
