Are facial responses to taste stimulation and recognition of them supported by domain-specific or domain-general mechanism? We examined facial responses elicited by taste stimulation (sweet, salty, sour, and bitter). Solution of each taste was injected into the subjects' mouths and their facial responses were recorded. Next, the pictures or movies of the facial responses were presented to the subjects who were required to identify the taste stimuli on the confidence rating scale and to rate emotional tone of the facial expressions. The results of the experiments showed that the facial expression of sourness and bitterness were conspicuous and identified correctly. These findings together with the other relative findings were discussed in terms of the evolutional meanings and domain-specificity/generality.
