Feedback Inhibition00:46

Feedback Inhibition

44.1K
Biochemical reactions are occurring constantly in cells, converting starting substances to different products, usually with the help of enzymes that speed the reactions. Without enzymes, it would take far too long for most reactions to occur to be useful to the cell!

Confirmation Biases01:31

Confirmation Biases

6.0K
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?

Framing Effects03:26

Framing Effects

7.8K
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...

Subliminal Perception01:15

Subliminal Perception

1.1K
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...

Halo Effect01:27

Halo Effect

806
The halo effect is a cognitive bias in which an individual's overall impression influences judgments about their specific traits. This psychological phenomenon leads people to associate positive characteristics with those they perceive as generally good and negative characteristics with those they view as bad. This effect is particularly influential in social perception, professional evaluations, and decision-making processes.The Psychological Basis of the Halo EffectThe halo effect is rooted...

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.
  • 视觉感知 视觉感知 视觉感知

背景情况:

  • 众所周知,否定陈述与肯定陈述相比,需要更大的认知处理努力.
  • 适应重复的否定可能会发生,这可能会随着时间的推移减轻处理需求.
  • 否定对视觉处理和适应程度的具体影响仍然是需要研究的领域.

研究的目的:

  • 调查否定是否阻碍视觉处理.
  • 为了确定连续重复否定是否会减轻它们对视觉处理的影响.
  • 量化评估注意力能力及其在否定和断言条件下的分布.

主要方法:

  • 利用视觉注意力 (TVA) 的正式理论来测量注意力容量和分布.
  • 采用时间顺序判断 (TOJ) 范式,使用二进制否定.
  • 进行了三项实验,以否定和断言指令评估性能.

主要成果:

  • 否定的指令在认知上要求很高,导致整体注意力能力的减少.
  • 注意力能力逐渐恢复,但与断言相比,即使在经过大量的重复之后,也停滞在较低的水平上.
  • 否定导致注意力在目标和参考刺激之间均分配,而断言则将注意力转移到目标.

结论:

  • 否定给人带来了相当大的认知负载,减少了可用于视觉任务的可用处理资源.
  • 否定的重复提供了有限的适应性,无法恢复注意力能力到断言水平.
  • 了解由否定与断言引起的注意力转移对于优化各种环境中的信息处理至关重要.
