Abstract

Reaction times and perceived intensities for NaCl solutions were measured in sixteen human adults. Stimulus delivery was by means of a circular piece of solution-soaked filter paper held with forceps. The reaction time (T) decreased and the perceived intensity (S) increased with increasing the concentration (C) of NaCl solution applied to a fixed (78.5 mm2) tongue area. The comprehensive relations among T, S and C can be expressed by the following formulae; T = a + b log( C C0), T = p + q log( S S0), and logS = mlogC + logn, where a, b, p, q, m, n = constants, and S0 indicates the perceived intensity at the threshold concentration (C0). Meanwhile, the reaction time decreased and the perceived intensity increased with increasing the stimulated area (A) under a fixed (1.0 M) concentration of NaCl solution. The relations among T, S and A can also be expressed by the following equations; T = a′ + b′ log( A A0), T = p′ + q′ log( S S0), and logS = m′logA + logn′, where a′, b′, p′, q′, m′, n′ = constants, and A0 indicates the threshold size of stimulated area.
