概括
当人们预见到分散注意力的因素时,他们变得更加警,而不是更少. 这种高度警觉或准备效应会影响早期的视觉处理,而不仅仅是运动反应.
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:
- 以前的研究表明,观察者可能会在分心出现之前抑制分心因素.
- 最近的发现表明,当预测干扰因素时,个人更警,类似于为任务相关的刺激做准备.
- 这种准备效应主要在加速点探测任务中观察到,其对其他认知过程的影响尚不清楚.
研究的目的:
- 为了调查预测分心因素时观察到的准备效应是否会影响早期的视觉过程.
- 为了确定这种制剂效果是否超出了发动机制剂.
- 通过使用内存编码任务而不是加速的点探测任务来检查准备效应的灵活性.
主要方法:
- 通过使用带有内存编码的变化检测任务进行了两个实验.
- 参与者在信息,分心或无显示块期间执行了变化检测任务.
- 通过在预期的展示时间内呈现信件来测试注意力,要求参与者回忆它们.
主要成果:
- 变更检测性能在信息显示器中最高,在分心显示器中最低.
- 当参与者预期信息或分散注意力的刺激时,信件回忆显著增加,这些预期条件之间没有显著差异.
- 这表明,为两种类型的刺激做准备同样可以增强早期视觉处理.
结论:
- 准备效应影响早期的视觉过程,超越了运动准备.

01:08Timing and Consequences on Behavior
71
In operant conditioning, the timing of reinforcement is crucial. For animals like rats and cats, immediate reinforcement (within a few seconds) is much more effective than delayed reinforcement. For example, a food reward for a rat needs to follow within 30 seconds of pressing a bar to be effective.
Humans, however, can respond to delayed reinforcers. We often make decisions between immediate small rewards and delayed larger rewards. This ability to delay gratification is a significant...

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?

Controlled processes in human consciousness represent high-alert mental states where individuals deliberately focus their attention on achieving specific goals. Controlled processes can be seen in situations like mastering new technology, where a person might become so absorbed that they ignore surrounding distractions. Such processes involve selective attention, requiring one to concentrate on particular elements of experience while disregarding others. These are governed by executive...

01:04Social Facilitation
31.7K
Not all intergroup interactions lead to negative outcomes. Sometimes, being in a group situation can improve performance. Social facilitation occurs when an individual performs better when an audience is watching than when the individual performs the behavior alone. This typically occurs when people are performing a task for which they are skilled.

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...

People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about...
