A contribution to the mathematical biophysics of psychophysical discrimination II

  • H. D. Landahl


The properties of a neural mechanism previously discussed are given in more general form. It is shown that, under certain conditions, a psychophysical scale value is proportional to a difference between excitation factors at a synapse. More general relations are derived which hold among different variables in the two and three categories of judgment. An attempt is made to apply the results to the method of choices. Certain relations derived are compared with available experimental data.
