概括
在模拟环境中",默认+"推动减少了食二氧化碳排放,但效果不是持久的. 这两种干预措施都没有增强消费者对可持续消费的责任.
科学领域:
- 环境心理学
- 行为经济学
- 可持续的粮食系统
背景情况:
- 全球粮食系统对温室气体排放做出了重大贡献,需要改变饮食以缓解气候变化.
- 推动影响选择,但也引起了人们对自主权和持续变革的担忧;推动的目标是提高消费者的能力.
- 关于推动与促进的比较研究,特别是关于消费者对可持续消费的责任 (CRSC) 的研究,是有限的.
研究的目的:
- 为了比较"默认+"推进和"信息+"推进在减少食物选择的碳足迹方面的有效性.
- 研究消费者对可持续消费的责任 (CRSC) 作为干预效应的调解者.
- 评估推动和促进可持续食物选择的持续性.
主要方法:
- 一个混合设计的实验与664德国消费者在模拟的食品交付设置.
- 三个条件:一个"默认+"的推动力,一个"信息+"的推动力,和一个对照组.
- 通过两个调查波 (干预和后续) 收集的数据测量假设的餐饮选择和二氧化碳足迹.
主要成果:
- 与对照组相比,推动干预显著降低了与餐饮相关的二氧化碳排放.
- 推动干预对二氧化碳排放的影响较小且不太一致.
- 在随访中,这两种干预都没有显示持久的效果,并且这两种干预都没有显著增加CRSC.
结论:
- 虽然推动可以减少即时的碳足迹,但它们可能不会促进长期的可持续消费或增强消费者的责任.
- 在这种情况下,促进干预的效果似乎不如减少排放的推动力.
- 未来的干预措施应考虑直接培养消费者对可持续食品选择的责任.

Persuasion Strategies
39.6K
Researchers have tested many persuasion strategies, including the foot-in-the door and the door-in-the-face techniques, in a variety of contexts. Ultimately, the principles are effective in selling products and changing people’s attitude, ideas, and behaviors (Cialdini & Goldstein, 2004).

Confirmation Biases
7.2K
The confirmation bias is the tendency to focus on information that confirms our existing beliefs and ignore information that is inconsistent with our expectations. For example, if you think that your professor is not very nice, you notice all of the instances of rude behavior exhibited by the professor while ignoring the countless pleasant interactions he is involved in on a daily basis. Have you ever fallen prey to the confirmation bias, either as the source or target of such bias?

Regulation of Food Intake
350
Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...

Self-Discrepancy Theory

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

Drive-Reduction Theory: Push Theory of Motivation
555
Clark Hull's drive-reduction theory, introduced in the 1940s and 1950s and often termed the "push theory" of motivation, provides a framework for understanding how biological and learned drives influence behavior. Hull suggested that motivation originates from the need to alleviate physiological tension caused by unmet biological necessities. The theory proposes that when a basic need, such as hunger or sleep, goes unfulfilled, it creates an internal imbalance. This imbalance, or...

Framing Effects
7.5K
Information is everywhere and its presentation—such as how and when items are presented—can impact our perceptions and decisions surrounding the info. This broad concept umbrellas framing effects—influences that occur due to the way information is framed in its appearance, whether it’s purely the order or the specific wording of a message. Let’s take a look at numerous ways in which two versions of something can objectively say the same thing, yet we respond in...
