概括
收益框架的信息比损失框架的信息更能激活腹中前额叶皮层 (VMPFC),特别是对于个人相关的结果. 在消息编码期间的VMPFC活动预测了行为和感知到的有效性.
科学领域:
- 神经科学是一个神经科学.
- 社会心理学 社会心理学
- 神经成像是一种神经成像.
背景情况:
- 在说服性信息编码期间,腹中前额叶皮层 (VMPFC) 的活动预测了行为.
- 了解神经对不同信息特征的反应对于优化说服至关重要.
- 目前存在关于特定信息特征如何影响大脑活动的知识差距.
研究的目的:
- 研究说服性信息框架的神经相关性 (获利与损失).
- 检查消息框架如何与调制VMPFC活动中的自我相关性相互作用.
- 探索VMPFC激活,感知消息有效性和行为之间的关系.
主要方法:
- 功能磁共振成像 (fMRI) 用于测量消息编码期间的VMPFC活动.
- 将大脑对收益框架与损失框架的说服性信息的反应进行比较.
- 在VMPFC激活,自我报告的消息有效性和行为结果之间的相关性分析.
主要成果:
- 与损失框架的消息相比,收益框架的消息引起了显著更大的VMPFC激活.
- 当信息涉及到直接经历的结果 (即与自身相关) 时,这种效应更为明显.
- 自我报告的消息有效性与VMPFC激活有积极的相关性,而获取框架的消息被认为更有效.
结论:

7.4K
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...

Persuasion is the process of changing our attitude toward something based on some kind of communication. Much of the persuasion we experience comes from outside forces. How do people convince others to change their attitudes, beliefs, and behaviors? What communications do you receive that attempt to persuade you to change your attitudes, beliefs, and behaviors?

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).

People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about...

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.

Charles Darwin proposed that facial expressions are an evolutionary adaptation for communication. He argued that these expressions are not influenced by culture but are universal across species. For example, a snarling expression with exposed teeth signals a threat in many animals, including humans. Darwin also suggested that displaying an emotion can intensify the feeling. Smiling, for example, could enhance one's sense of happiness. This idea laid the foundation for understanding the role...
