概括
突出的分心因素可能不会自动吸引注意力. 这项研究发现,早期的刺激被批评不那么突出,实际上更突出,挑战了刺激驱动的注意力理论.
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.
- 视觉注意力 视觉注意力
背景情况:
- 突出在注意力控制中的作用受到辩论,信号抑制假设表明突出刺激可以由上向下控制.
- 有批评说,之前的研究使用了弱突出的分心因子,质疑了关于注意力捕捉的研究结果的有效性.
- 缺乏共同的突出性衡量标准阻碍了对低突出性批评的评估.
研究的目的:
- 客观地测量和比较用于关键注意力控制研究中的分心因子的突出性.
- 测试分心器突出度的增加是否会导致注意力捕获,正如低突出度批评所预测的那样.
主要方法:
- 利用一种新的心理物理技术来量化和比较不同研究中的分心因子的突出性.
- 进行了后续实验,以调查观察到的突出差异的原因,并测试注意力捕捉预测.
主要成果:
- 令人惊的是,以前被认为是微弱突出的分心因子被发现比后来的研究中更突出.
- 确定了导致原始刺激的突出性更高的因素.
- 进一步增加显著性并没有像低显著性账户预测的那样引起注意.
结论:
- 这些发现挑战了那些仅依赖于自下而上的,刺激驱动的注意力控制理论的理论.
- 表明注意力捕捉不仅仅由刺激的突出性决定.
- 突出了注意力机制的复杂性,涉及刺激特性和控制过程之间的相互作用.

Subliminal Perception
247
Subliminal perception refers to the processing of sensory information that occurs below the level of conscious awareness. Researchers study subliminal perception by presenting a stimulus, such as a word or image, very quickly, typically around 50 milliseconds. This rapid presentation is often followed by another stimulus, such as a pattern of dots or lines, which blocks further mental processing of the initial stimulus. As a result, if participants cannot identify the initial stimulus better...

Confirmation Biases
5.5K
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?

Cause 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?

Stereotypes, Prejudice, and Discrimination

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...
