概括
学习的可信度没有影响通过快速定期视觉刺激 (FPVS) 测量的大脑反应,与基于外表的可信度不同. 这表明学习的印象与感知到的可信度被处理的方式不同.
科学领域:
- 认知神经科学 认知神经科学
- 社会心理学 社会心理学
- 神经科学是一个神经科学.
背景情况:
- 快速定期视觉刺激 (FPVS) 可以检测隐含的反应,以面对可信度.
- 人们很容易从脸上提取情感关联,这促使人们对学到的可信度进行调查.
研究的目的:
- 用FPVS. 调查学习的可信度是否会引起类似的脑电图 (EEG) 反应,就像使用FPVS. 感知面部可信度一样.
- 为了确定与行为学到的关联是否会影响神经对面部反应.
主要方法:
- 参与者在观看6赫兹的奇怪面孔序列时进行了EEG记录,每五张面孔 (1.2赫兹) 呈现一个奇怪面孔.
- 在EEG记录之前,面部与值得信赖或不值得信赖的行为有关.
- 在1.2Hz的奇特球响应及其波被分析在双边皮皮质上.
主要成果:
- 对于学到的与新鲜的面孔来说,观察到更强烈的奇怪反应,证实了学习.
- 与之前的研究一致,看起来不那么值得信赖的奇怪面孔引发了比看起来值得信赖的人更强烈的反应.
- 重要的是,学习到的可信度并没有显著地影响奇怪的反应.
结论:
- 对学习到的可信度的神经反应与以外表为基础的可信度引起的不同.
- 这些发现表明,学习与感知的社会印象有不同的处理途径.
- 需要进一步的研究来探索刺激和设计,有效地测量使用FPVS学习的印象.

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

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...

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?
