Study on stimulus concentrations for better identification after cross-adaptation and selective adaptation in a chemical sensory experiment. Results suggest 1mM and 5mM concentrations yield optimal identification.

Frank et al, 2010 CS 10-069 Supplementary Figure 1. Experiment 1--Concentration of Adapt-Test Stimuli Unmatched in Concentration and Identification of Test Stimuli. (A) After cross-adaptation and self-adaptation, single compounds were better identified if the adapt stimulus concentration was 1 mM or the test stimulus concentration was 5 mM. (B) After selective adaptation, extra and ambient mixture-components were better identified when the extra and adapt (continuing ambient) stimulus concentration was 5 mM. Means ( sem) are plotted.
