概括
面部表情的统计规律性会影响我们如何感知情绪. 我们的研究表明,可预测性,特别是从局部线索,指导组合编码缺失的情感表达.
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.
- 计算机视觉 计算机视觉
背景情况:
- 人类利用集合编码来有效地从动态面部表情中解释情绪状态.
- 统计规律对感知缺失的面部表情的影响仍未得到充分研究.
研究的目的:
- 调查面部表情时间序列中的统计规律如何影响缺失表情的感知平均值.
- 确定本地和全球规律是否对集体编码产生不同影响.
主要方法:
- 实验1a/1b:通过改变缺少的面部表情的位置来操纵局部规律 (中性-厌恶/快乐).
- 实验2:通过在一个区块内保持一致的情绪方向来引入全球规律,以预测早期缺失的表达.
- 测量整体估计,以评估可预测性对感知平均值的影响.
主要成果:
- 当局规律性提供了足够的可预测性 (例如,晚期位置的缺失表情) 时,整体估计偏向于呈现和缺失面部的平均值.
- 添加全球规律性线索并没有增强早期缺失表达式对集合估计的影响,正如假设的那样.
- 研究结果表明,不同层次的预测编码可能对平均时间排序的面部表情产生不同的影响.
结论:
- 从局部统计规律得出的可预测性显著影响了缺少项目的时间顺序的面部表情的感知平均值.
- 在面部表情的预测编码中,与局部规律相比,全球规律可能会产生质量上不同的影响.
- 未来的研究应该探索层次预测编码对集体感知的细微贡献.

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?

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...

01:31Confirmation Biases
5.4K
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?

01:53Cause and Effect

While variables are sometimes correlated because one does cause the other, it could also be that some other factor, a confounding variable, is actually causing the systematic movement in our variables of interest. For instance, as sales in ice cream increase, so does the overall rate of crime. Is it possible that indulging in your favorite flavor of ice cream could send you on a crime spree? Or, after committing crime do you think you might decide to treat yourself to a cone?

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...
