The "Linguameter": a device for investigating tongue-muscle control.
A device we call a Linguameter is described. It allows measurement of subjects' abilities to position their tongues at points in the horizontal plane. Results with a prototype are reported for three tasks. All subjects could reproduce, bisect, and transpose arbitrary intervals with a very high degree of accuracy. This highly accurate normal performance, coupled with the sensitivity of the device, may make it of interest in studies of the oral or other sensory-motor system's normal functioning, as well as in investigations of sensory-motor pathology.
