Abstract

Promoting sustainable diets is consistently documented to be beneficial to health, the environment, and long-term food security. There remains limited understanding of the effects of activating the goal of sustainable diets for achieving co-benefits on sustainable food choices and the potential mechanisms. This study was a pre-registered online randomized controlled trial combined with eye tracking to compare the effects of three priming interventions: health-benefit priming (HP), environment-benefit priming (EP), and combined-benefit priming (CoP), on sustainable food choice. Sustainable food choices were assessed by a simulated online shopping task. Participants' eye movement data were tracked while they were choosing foods during simulated online shopping. Participants' executive function (EF), environmental values, health values, and social orientation values were also measured. The results showed a significant difference in sustainable food choices among the four groups, with CoP showing a significant increase compared to the control. The eye-tracking data revealed that the attention to sustainable foods with an eco-friendly logo mediated the association between priming and participants’ sustainable food choices. Furthermore, priming with the co-benefits of sustainable diets can be more effective for participants with greater delay discounting to increase their sustainable food choices. These findings suggest that priming with co-benefits of sustainable diets can be a promising strategy to support more sustainable food choices particularly for consumers with more difficulty in delaying their immediate awards.

测试健康益处、环境益处和共同益处引物对促进可持续食品选择的影响及其心理机制：结合眼动仪的随机对照试验

有资料表明，提倡可持续膳食有利于健康、环境和长期粮食安全。人们对激活可持续膳食目标以实现可持续食品选择共同利益的效果以及潜在机制的了解仍然有限。本研究是一项预先登记的在线随机对照试验，结合眼动追踪技术，比较了三种诱导干预措施对可持续食品选择的影响：健康益处诱导（HP）、环境益处诱导（EP）和综合益处诱导（CoP）。可持续食品选择通过模拟在线购物任务进行评估。在模拟网上购物过程中，对参与者选择食品时的眼动数据进行跟踪。此外，还测量了参与者的执行功能（EF）、环境价值观、健康价值观和社会导向价值观。结果显示，四组参与者在可持续食品选择方面存在显著差异，其中 CoP 比对照组显著增加。眼动跟踪数据显示，对带有环保标志的可持续食品的关注在诱导与参与者的可持续食品选择之间起到了中介作用。此外，以可持续饮食的共同益处为引子，对于延迟折扣较高的参与者来说，能更有效地增加他们对可持续食品的选择。这些研究结果表明，以可持续饮食的共同益处为引子是一种很有前景的策略，可以支持更多的可持续食品选择，尤其是对于那些更难延迟即时奖励的消费者。

期刊介绍： The Journal of Environmental Psychology is the premier journal in the field, serving individuals in a wide range of disciplines who have an interest in the scientific study of the transactions and interrelationships between people and their surroundings (including built, social, natural and virtual environments, the use and abuse of nature and natural resources, and sustainability-related behavior). The journal publishes internationally contributed empirical studies and reviews of research on these topics that advance new insights. As an important forum for the field, the journal publishes some of the most influential papers in the discipline that reflect the scientific development of environmental psychology. Contributions on theoretical, methodological, and practical aspects of all human-environment interactions are welcome, along with innovative or interdisciplinary approaches that have a psychological emphasis. Research areas include: •Psychological and behavioral aspects of people and nature •Cognitive mapping, spatial cognition and wayfinding •Ecological consequences of human actions •Theories of place, place attachment, and place identity •Environmental risks and hazards: perception, behavior, and management •Perception and evaluation of buildings and natural landscapes •Effects of physical and natural settings on human cognition and health •Theories of proenvironmental behavior, norms, attitudes, and personality •Psychology of sustainability and climate change •Psychological aspects of resource management and crises •Social use of space: crowding, privacy, territoriality, personal space •Design of, and experiences related to, the physical aspects of workplaces, schools, residences, public buildings and public space
