Comparing Concurrent Choice and Demand Curve Procedures as Assessments of Reinforcer Value

Abstract

The current study tested both of these preference measures using the same subjects (Sprague Dawley rats) who could earn two reinforcer types: Ensure liquid diet and grain pellets. Results from this study can provide further evidence as to whether the results of these preference measures align, and can advance our understanding of the factors that influence the valuation of a commodity.
