Factors influencing capacity to judge direction of tactile stimulus movement on the face

J Dent Res. 1979 Nov;58(11):2052-7. doi: 10.1177/00220345790580110301.


The influence of stimulus velocity and traverse length on a subject's ability to indicate direction of brush movement across perioral skin was determined using a forced-choice procedure. The data show that correct identification of brush direction increases with traverse length and is optimal for velocities between 3 and 25 cm/sec.
