Interaction between stimuli with different taste qualities evaluated by reaction time.
The influence of adaptation to taste stimuli of 1 quality on tastants with other qualities was investigated by comparing the reaction time (RT) to a test solution after adapting-solution flow with the RT to the same test solution after water flow. Adapting solutions were strong concentrations of NaCl, HCl, QHCl, and sucrose; test solutions were the same compounds but in lower concentrations. Adaptation to sucrose significantly shortened RT to NaCl and HCl, and to a lesser degree to QHCl. A similar cross-enhancement was found in sucrose when other compounds served as adapting solutions, In all other taste combinations, only a cross-adaptation effect was observed. Results are discussed in relation to some adaptation phenomena, water taste data, and magnitude-estimation data.
