An Apparatus and Method for Rigorously Controlling Amount of Reward and Amount of Consummatory Activity

Abstract

This paper outlines shortcomings of studies using food pellets of varying size or number as a technique for quantifying and varying amount of reward and/or amount of consummatory activity. An apparatus, utilizing a “drinkometer” circuit in conjunction with a stepping relay, is described. It presents fluid incentives and yields a high degree of precision and control of various parameters of reward, including consummatory activity.
