Abstract
When the minimal discriminable increment of intensity Al is measured as a function of L. (i.e., I2[long dash]I1=[DELTA]I), the relative variation of [DELTA]I is constant (independent of I1). If, using the same manipulative procedure. I1 is detd. as a function of fixed AI (by I2[long dash]I1=[DELTA]I), the relative variation of unspecified1 is directly proportional to d log I/d log [DELTA]I, and is a complex function of I1. This result is uniquely predicted by the principle that the observed variation is due primarily to the fluctuating reactive capacity of the organism.This publication has 6 references indexed in Scilit:
