概括
当搜索策略已知时,视觉注意力可以抑制无关紧要的突出项目. 然而,由特定显示类型引发的单元搜索模式,即使在许多项目中,也防止了这种抑制.
科学领域:
- 认知心理学 认知心理学
- 视觉注意力研究 视觉注意力研究
- 人类的感知 人类的感知
背景情况:
- 注意力被吸引到突出的视觉刺激.
- 不相关突出物品的已知特征可以被抑制,从而促进搜索.
- 之前的研究讨论了分散注意力的突出性和显示密度对注意力的影响.
研究的目的:
- 调查搜索策略是否会影响在更大的集大小中抑制无关紧要的分心因素.
- 为了测试单元搜索模式的假设,与特征搜索模式不同,减弱分心抑制.
- 在视觉搜索中协调关于分心器突出和设置大小的相互矛盾的发现.
主要方法:
- 使用了两种类型的搜索显示器:重复非目标 (R-NT) 显示器促进单元搜索和异质非目标显示器促进功能搜索.
- 实验操纵了显示类型及其在块中的比例,以影响参与者采用的搜索策略.
- 测量了反应时间和准确性,以评估注意力捕捉和分心抑制.
主要成果:
- 干扰因子抑制发生在异质显示中,但在单独呈现时,在R-NT显示中没有发生.
- 当R-NT显示占多数时,这两种显示类型的抑制都减弱了.
- 当异质显示器占多数时,在两个显示器类型中都观察到抑制.
结论:
- 在大型集大小中抑制无关突出的分心因素的能力取决于所采用的搜索策略.
- 鼓励单元搜索的显示器可以防止干扰因子抑制,无论设置大小如何.
- 搜索策略,而不仅仅是显示密度,是理解注意力控制和分心抑制的关键因素.

Enzymes
80.4K
Inside living organisms, enzymes act as catalysts for many biochemical reactions involved in cellular metabolism. The role of enzymes is to reduce the activation energies of biochemical reactions by forming complexes with its substrates. The lowering of activation energies favor an increase in the rates of biochemical reactions.
Enzyme deficiencies can often translate into life-threatening diseases. For example, a genetic abnormality resulting in the deficiency of the enzyme G6PD...

Feedback Inhibition

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!

Enzyme Inhibition
77.8K
Inhibitors are molecules that reduce enzyme activity by binding to the enzyme. In a normally functioning cell, enzymes are regulated by a variety of inhibitors. Drugs and other toxins can also inhibit enzymes. Some inhibitors bind to the enzyme’s active site, while others inhibit enzymatic activity by binding to other sites on the protein structure.

Subliminal Perception
233
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...
