简要总结
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.

结局指标
主要结局
Participants' choice of sustainable foods
时间窗: Immediately after they are exposed to priming manipulation
Measure name: Participants' food choice for sustainable food Measure tool: E-prime Measure process: During the computerized task, participants will examine a series of food products. Subsequently participants will be directed to simulated webpage for online shopping with all the foods they have examined available and they are required to buy three products they like most with the available budget provided. Measure units: Participants' actual food choice, whether they prefer choosing more sustainable food.
Participants' facial expression
时间窗: Immediately after they are exposed to priming manipulation
Measure name: Participants' facial expression measured by pupil diameters Measure tool: E-prime with Tobii Pro eye trackers Measure units: Pupil diameters will be used to compare difference when participants view the less or more sustainable foods. The larger pupillary variations is an indicator of interest in the products.
Participants' eye movement data
时间窗: Immediately after they are exposed to priming manipulation
Measure name: Participants' eye movement data Measure tool: E-prime with Tobii Pro eye trackers Measure units: Count frequency of looking at the environmentally friendly logo for each food category. Greater number indicates greater degree of attention and interest.
次要结局
- Social orientation value(Immediately after they complete the computerized task with priming manipulation)
- Pro-environmental values(Immediately after they complete the computerized task with priming manipulation)
