In-mouth air cavity (IMAC) volume at four time points after swallowing in the two experiments.

<p>In both experiments, the IMACs of the two subject groups were significantly different (ANOVA, SNK), although the groups were formed <i>a posteriori</i> in Experiment 1 and <i>a priori</i> on the basis of aroma release in Experiment 2. Note that the mean IMAC was similar in the two experiments.
