概括
更高的数学焦虑与更强的感知偏见有关,特别是中心倾向和串行依赖效应. 这些效应源于感官精度降低,而不是记忆,突出表明心理特征对感知的影响.
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.
- 感知 感知 感知 感知
背景情况:
- 感知依赖于将当前感官输入与先前知识相结合.
- 历史效应,如中心倾向和串行依赖,平滑噪音感官数据,但引入偏差.
- 这些动态感知过程的潜在机制和心理特征的影响还不太清楚.
研究的目的:
- 调查数学焦虑对视觉感知中的历史效应的影响.
- 用视觉数量任务比较不同程度的数学焦虑的人群中的序列依赖和中心倾向效应.
主要方法:
- 使用视觉数量任务来测量序列依赖和中心倾向效应.

41.9K
When we hold a stereotype about a person, we have expectations that he or she will fulfill that stereotype. A self-fulfilling prophecy is an expectation held by a person that alters his or her behavior in a way that tends to make it true. When we hold stereotypes about a person, we tend to treat the person according to our expectations. This treatment can influence the person to act according to our stereotypic expectations, thus confirming our stereotypic beliefs. Research by Rosenthal and...

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?

Visual agnosia is a condition characterized by the inability to recognize visually presented objects despite having normal vision. For instance, a person with visual agnosia can describe the shape and color of an object but cannot identify or name it. This impairment does not affect their visual field, acuity, color vision, brightness discrimination, language, or memory. An example of this condition in a social setting is someone at a dinner party asking for "that silver thing with a round...
