感覚の時間的優位性（TDS）
TDS, a sensory method recording the most attention-grabbing dominant attribute at each moment over time. It is distinct from a time course of intensity.

Reading the bitterness
Temporal dominance of sensations (TDS) is a sensory method in which respondents continuously select the sensation drawing the most attention from the moment food enters the mouth until the sensations fade. In a study using strawberries, participants selected the most salient option among taste, aroma, and mouthfeel from first contact until sensation ended, recording the times selected as a line. It follows which of several sensations takes the leading role over time, rather than how strong an individual sensation such as bitterness remains throughout.
This measures something different from the time-intensity method, which continuously scores the strength of one sensation. Even if bitterness has a high proportion of selections at a given point in TDS, that indicates it was most salient then; it does not directly show bitterness intensity itself, pleasantness, or how long intensity stayed high. It has also been pointed out that a sensation selected as most salient need not always be the most intense.
The framework has also been applied to beverages. A study of 9 beers named its analysis from consumption through before and after swallowing the Flavor Life Cycle and showed dominant flavors changing around swallowing. This is not a new independent scale, but a framework for one analysis using TDS; the account has been checked only at abstract level.

Scope: An evaluation method that follows a person from taking food into the mouth until the sensation fades
Note: This is not a method that records the intensity of multiple sensations, such as sweetness and bitterness, at the same time.
