 Many scientists today think this is a synesthetic cross-modal association between the shape of the object and the phonemic inflection that the word makes when forming the word in the mouth.A similar “bouba” and “Kiki” food-word association study tested the synesthetic cross-modal associations of words and food tastes in neurologically normal participants.It was found that the participants could pick out certain abstract clues from the different foods tasted and associate them in a significant manner to meaningless non-words.
