概括
注意力被不确定的奖励所吸引,即使学习是不必要的. 这种不确定性调制的注意力捕获 (UMAC) 是由预测错误驱动的,而不是明确的指令,这表明隐含的学习机制.
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.
- 决策 决策 决策 决策
背景情况:
- 关注优先级受奖励不确定性的影响.
- 与可变奖励相关的刺激比具有可预测结果的刺激更容易引起注意.
- 这挑战了那些认为认知主要减少不确定性的理论.
研究的目的:
- 调查是否不确定性调制的注意力捕获 (UMAC) 服务于学习的注意力.
- 确定明确指令或预测错误是否驱动UMAC.
- 澄清学习在对不确定的刺激的注意力优先排序中的作用.
主要方法:
- 两个实验检查了明确指令对奖励预测错误对UMAC的影响.
- 实验1:用明确的指令否定学习需求来评估UMAC.
- 实验2:用奖励反来评估UMAC,但没有明确的指令.
主要成果:
- 明确的指令并没有减少UMAC效应,表明它不仅仅是学习的战略关注.
- UMAC并非仅由指令生成,这突显了奖励反的作用.
- 对UMAC来说,对预测错误的直接经验至关重要.
结论:
- UMAC不仅仅是一个战略性的注意力学习过程.
- 研究结果表明,UMAC可能是隐式运行或反映注意力系统来检测经历的不确定性.

The Anchoring-and-Adjustment Heuristic

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...

High-Level and Low-Level Awareness
247
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...

Reason and Intuition
6.4K
The human brain processes information for decision-making using one of two routes: an intuitive system and a rational system (Epstein, 1994; popularized by Kahneman, 2011 as System 1 and System 2, respectively). The intuitive system is quick, impulsive, and operates with minimal effort, relying on emotions or habits to provide cues for what to do next, while the rational system is logical, analytical, deliberate, and methodical. Research in neuropsychology suggests that the...

The Availability Heuristic

A heuristic is a general problem-solving framework (Tversky & Kahneman, 1974). You can think of these as mental shortcuts that are used to solve problems. Different types of heuristics are used in different types of situations, and the impulse to use a heuristic occurs when one of five conditions is met (Pratkanis, 1989):
