Note. For each group, means were calculated for all bolus dwell times greater than zero. The percentage of participants within each age group who had a bolus dwell time greater than zero is provided in parentheses to the right of the bolus dwell time mean. The soy milk, cup condition was not acquired from participants to limit total volume consumed in one sitting.
