概括
自参照效应 (SRE) 可能不是来自早期的注意力提升. 相反,对自我关联项目的谨慎决策值可能解释记忆优势,这表明决策层面的因素是关键.
科学领域:
- 认知心理学 认知心理学
- 神经科学是一个神经科学.
背景情况:
- 自参照效应 (SRE) 增强了对自我关联刺激的记忆.
- 以前的理论提出SRE是由早期视觉处理中的注意力提升驱动的,就像自我注意网络 (SAN).
- 这表明自我相关性应该克服因退化的刺激引起的记忆缺陷.
研究的目的:
- 调查SAN提出的注意力增强是否发生在编码或检索过程中.
- 测试是否自我相关性在视觉退化刺激中对抗记忆障碍.
- 探索SRE背后的决策机制.
主要方法:
- 两项实验使用计算机化购物任务,对自己和他人拥有的物品进行分类.
- 实验1在编码时操纵低对比度;实验2在检索时操纵低对比度.
- 一个分层线性弹道积累器模型分析了内存性能.
主要成果:
- 无论是编码还是检索,低对比度操纵都没有产生行为SRE.
- 源内存准确度对于自有和其他自有对象是相同的.
- 该模型显示了自有物体的谨慎决策值.
结论:
- SRE可能受到决策层面的因素的影响,而不仅仅是早期的注意力过程.
- 对自我关联项目的谨慎决策值可能会解释记忆优势.
- 决策层面的因素可能比以前认为的在SRE中发挥更重要的作用.

Hindsight Biases
3.4K
Hindsight bias leads you to believe that the event you just experienced was predictable, even though it really wasn’t. In other words, you knew all along that things would turn out the way they did. Can you relate this to the phrase "Hindsight is 20/20" now?

Implicit Memories
63
Implicit memories, also known as non-declarative memories, are long-term memories that function outside of conscious awareness. These memories influence behavior and skills without explicit knowledge. This type of memory is evident in tasks like playing tennis, snowboarding, and texting. Implicit memory has three subsystems: procedural memory, conditioning, and priming. This type of memory is essential in various activities, from everyday tasks to specialized skills.

Self-Schemas
30.8K
In general, a schema is a mental construct consisting of a cluster or collection of related concepts (Bartlett, 1932). There are many different types of schemata, and they all have one thing in common: schemata are a method of organizing information that allows the brain to work more efficiently. When a schema is activated, the brain makes immediate assumptions about the person or object being observed.

Reason and Intuition
6.3K
The human brain processes information for decision-making using one of two routes: an intuitive system and a rational system (Epstein, 1994; popularized by Kahneman, 2011 as System 1 and System 2, respectively). The intuitive system is quick, impulsive, and operates with minimal effort, relying on emotions or habits to provide cues for what to do next, while the rational system is logical, analytical, deliberate, and methodical. Research in neuropsychology suggests that the...

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.

Stereotypes, Prejudice, and Discrimination
89.8K
Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...
