Poisson transduction of noise stimuli: some results of a computer simulation.

Abstract

A Monte‐Carlo procedure was used to simulate noise‐intensity discrimination. Poisson transduction (with compression) was modeled in both ’’energy‐summation’’ and ’’neural‐summation’’ versions. Penner’s analysis [J. Math. Psychol. 9, 286–293 (1972)] of these two mechanisms was confirmed. When noise energies are analyzed into one‐third octave bands before being mapped onto counts, Weber functions and bandwidth reciprocities depart slightly from those given by an energy detector.
