Absolute taste thresholds for salt and sweetness were determined by a combination of ascending‐series and rating‐scale methods: for salt a value only very slightly under previous quoted figures was obtained, for sugar a value of .002 p/p was obtained. The results also permitted a scaling of each taste description on the rating‐scales in terms of both j.n.d's above threshold and solution concentrations. Previous workers have doubted whether there is one single absolute threshold for taste: the present r…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute of Drug Abuse of the National Institutes of Health.
