Consumers' Emotional Reaction to Sustainability Cue

This will be a randomized control trial (RCT) to examine whether the three priming interventions (health priming, environmental sustainability priming, and co-benefits priming) work to change consumers' sustainable food choice through their effects on changing consumers' emotional reaction when seeing foods with cues of environmental sustainability, which will be indicated by measuring consumers' facial expression, eye movement and pupil dilation.
