Sourness impacts envy and jealousy in Chinese culture

In the present study, five experiments (N = 233) were designed to explore whether sourness as a sensory experience could implicitly impact social emotions of envy and jealousy in Chinese culture. Experiment 1 (n = 63) explored the implicit conceptual association between sourness words (vs. bitterness words) and envy/jealousy words. Experiment 2 (n = 70) and 3 (n = 20) examined the priming effects of imagined and tasted sourness (vs. bitterness and sweetness) on self-rated emotional intensity in envy- and jealousy-arousing situations, respectively. Experiment 4 (n = 40) and 5 (n = 40) further testified the priming effects of imagined and tasted sourness (vs. bitterness and sweetness) on self-rated emotional intensity in four types of social situations (i.e., envy, jealousy, sad and happy events), respectively. In the results, sourness was found as the only taste that not only conceptually associated with envy/jealousy, but also significantly primed envy/jealousy feelings. The possible mechanism underlying the association of sourness-envy/jealousy was discussed.
