Eating Chocolate Ice Cream (05-20-20)

Xu and teammates conducted a multisensory analysis of how context influences impressions of chocolate ice cream eaten.  They determined that “When ice cream was consumed in the café, it was associated with . . . a sweet taste/flavour. When consumed in the university study area, it was correlated with . . . cocoa and milky flavours. Consumption at the city bus stop was correlated with . . . roasted and bitter tastes/flavours. The laboratory environment was only correlated with the attributes . . . creamy flavour. SC [skin conductance] was significantly increased in the university study area as compared to the laboratory, and HR [heart rate] was significantly decreased in the university study area environment as compared to the bus stop. . . .  The café soundscape had the highest sharpness, tonality, and fluctuation strength values as compared to the bus stop, university study area and laboratory environments. In addition, the bus stop soundscape had the highest roughness followed by café, laboratory and the university study area environments.”
