We report a cross-cultural study designed to investigate crossmodal correspondences between a variety of visual features (11 colors, 15 shapes, and 2 textures) and the five basic taste terms (bitter, salty, sour, sweet, and umami). A total of 452 participants from China, India, Malaysia, and the USA viewed color patches, shapes, and textures online and had to choose the taste term that best matched the image and then rate their confidence in their choice. Across the four groups of participants, the results revealed a number of crossmodal correspondences between certain colors/shapes and bitter, sour, and sweet tastes. Crossmodal correspondences were also documented between the color white and smooth/rough textures on the one hand and the salt taste on the other. Cross-cultural differences were observed in the correspondences between certain colors, shapes, and one of the textures and the taste terms. The taste-patterns shown by the participants from the four countries tested in the present study are quite different from one another, and these differences cannot easily be attributed merely to whether a country is Eastern or Western. These findings therefore highlight the impact of cultural background on crossmodal correspondences. As such, they raise a number of interesting questions regarding the neural mechanisms underlying crossmodal correspondences.
We report a cross-cultural study designed to investigate whether the type of receptacle in which a coloured beverage is presented influences the colour-flavour associations that consumers make. Participants from the United States of America (USA) and China were shown photographs of red, green, yellow, blue, orange, brown, and clear liquids in a water glass, a wine glass, a cocktail glass, and a plastic cup. The two groups of participants exhibited different colour-flavour associations for the green, yellow, orange, and brown drinks when these were presented in the different receptacles, suggesting some interesting interactions between the receptacle, colour, and flavour. Cross-cultural differences were also observed in the colour-flavour associations for red and blue drinks that were independent of the type of container in which the drinks were presented. These findings highlight the existence of an interaction between contextual factors (the receptacle in which a drink is presented) and the cultural background of our participants (China versus the USA) in terms of colour-flavour associations. Such results raise interesting questions regarding the underlying mechanisms responsible for these effects.
