概括
位置初始化 (PoL) 显示注意力被主动引导到最近选择的位置. 然而,当任务期望发生变化时,这种效应会灵活地减少,这表明注意力不是固定的.
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:
- 注意力往往偏向于最近参观的地点.
- 这种原始位置 (PoL) 效应表明在选定的地点自动增强注意力.
- 现有的理论预测PoL是独立于任务上下文.
研究的目的:
- 调查任务上下文的变化是否会影响位置的初始化 (PoL).
- 为了确定注意力偏差是否受到任务期望的调制.
- 检查主动注意力指导的灵活性.
主要方法:
- 参与者进行了交叉搜索,搜索探头和探头试验,任务概率各不相同.
- 在重复和更改的任务环境中测量了Priming-of-location (PoL).
- 任务概率和预先任务信息被操纵来改变预期.
主要成果:
- 在最初的实验中,尽管任务上下文发生了变化,但位置初始化 (PoL) 仍然很强大.
- 当参与者预计任务变化时,PoL显著下降.
- 期望任务切换减少了主动注意偏差.
结论:
- 位置初始化 (PoL) 是一种主动但灵活的注意力机制.
- 关注的优先级不是严格固定,而是适应不断变化的任务需求和期望.

The Availability Heuristic
5.8K
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):

The Anchoring-and-Adjustment Heuristic
7.2K
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...

Confirmation 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?

Cause and Effect
10.8K
While variables are sometimes correlated because one does cause the other, it could also be that some other factor, a confounding variable, is actually causing the systematic movement in our variables of interest. For instance, as sales in ice cream increase, so does the overall rate of crime. Is it possible that indulging in your favorite flavor of ice cream could send you on a crime spree? Or, after committing crime do you think you might decide to treat yourself to a cone?

Serial Position Effect
102
The serial position effect is a cognitive phenomenon where individuals are more likely to recall the first and last items in a list compared to those in the middle. This effect is divided into the primacy effect and the recency effect. The primacy effect is observed when the initial items in a list are remembered better. This occurs because these items are rehearsed more frequently or receive more elaborative processing, allowing them to be encoded into long-term memory more effectively. For...

Framing Effects
7.3K
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...
