概括
认知控制受到环境的影响,任务相关刺激的具体和抽象特征调节控制调整. 这些调整影响的是控制的强度,而不是时间,优化了冲突下的决策.
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.
- 人类的行为 人类的行为
背景情况:
- 认知控制是由上下文指导的,但机制尚未完全理解.
- 以前的研究将一致序列效应 (CSE) 与任务刺激的重复感知特征联系起来.
- 目前尚不清楚抽象特征或与任务无关的刺激是否会影响控制调整.
研究的目的:
- 调查抽象刺激特征和与任务无关的刺激是否将认知控制调整置于背景.
- 检查具体和抽象特征在调制一致性序列效应 (CSE) 中的作用.
- 为了确定CSE调制是否反映了控制强度或时间的变化.
主要方法:
- 在一个混最小化的prime-probe任务中采用了一种新的上下文操纵.
- 实验操纵了分心器-目标模式的重复或变化 (例如. 1) 和跨模式强度 (Exp. 2). 2). 2). 2). 2). 2). 2). 2). 2). 2). 2). 2). 2). 2). 2). 2). 2). 2). 2). 2). 2). 2). 2). 2). 2). 2). 2).
- 进一步的实验 (Exp. 3-4) 从先前的信号或背景刺激中测试了上下文. 使用分布式 (三角形图) 分析.
主要成果:
- 对于上下文重复而不是Exps.的变化,观察到更大的CSE. 1 和 2. 这两种情况.
- 这表明,与任务相关的刺激的具体特征 (模式) 和抽象特征 (强度) 都将控制置于背景中.
- CSE没有受到与任务无关的上下文操纵的影响 (Exps. 3,4) 的情况.
结论:
- 与任务相关的,具体和抽象的刺激特征将认知控制调整置于背景.
- 与任务无关的刺激特征不会调节控制调整.
- 情境调节CSE反映了认知控制强度的调整,而不是时间调整,有助于在冲突下做出决定.

Perceptual Constancy
411
Perceptual constancy is the ability to recognize that objects remain consistent and unchanged even when their appearance varies due to changes in sensory input. There are four main types of perceptual constancy: size constancy, shape constancy, color constancy, and brightness constancy.
Size constancy is the recognition that an object remains the same size, even when its image on the retina changes. For instance, a bus is perceived to be large enough to carry people, even if it looks tiny from...

The Anchoring-and-Adjustment Heuristic
7.3K
In order to make good decisions, we use our knowledge and our reasoning. Often, this knowledge and reasoning is sound and solid. However, sometimes, we are swayed by biases or by others manipulating a situation. For example, let’s say you and three friends wanted to rent a house and had a combined target budget of $1,600. The realtor shows you only very run-down houses for $1,600 and then shows you a very nice house for $2,000. Might you ask each person to pay more in rent to get the...

Language and Cognition
354
Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

Cognitivism

Cognitive psychology emerged as a significant field in the mid-20th century. It focused on understanding humans' internal mental processes. This approach emphasizes how people perceive, remember, think, and solve problems—elements critical to human cognition.
Previously dominated by behaviorism, which prioritized observable behaviors and largely ignored mental processes, psychology transformed in the 1950s. Cognitive psychologists argue that understanding how we think and process...

Framing Effects

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...
