概括

维护多个注意力模板允许特定的视觉搜索. 这项研究发现,持有两个模板与持有一个模板相比,不会降低特异性,表明强大的注意力控制.

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.
视觉感知视觉感知视觉感知

背景情况:

个人使用注意力模板来过感官信息.
以前的研究证实了同时持有多个模板的能力.
多个模板的表示质量和特异性仍然不清楚.

研究的目的:

为了确定是否保持两个注意力模板将表示质量限制在粗的信息上.
在多个模板活跃时,调查模板特异性的潜在下降.
探索视觉工作记忆在维持注意力模板特异性的作用.

主要方法:

使用空间暗示程序来评估注意力模板宽度.
参与者在不同的相似性条件下执行单目标和双目标色彩搜索任务.
模板特异性直接比较单模板和双模板维护条件.

主要成果:

在高相似性搜索期间,在单个和双重目标条件下观察到特定的模板维护.
在单个和双重目标搜索之间,没有发现模板特异性的显著差异.
模板特异性被证明取决于对视觉工作记忆的访问.

结论:

即使同时持有两个模板,注意力模板的特异性也保持不变.
双模板维护不需要降低表示精度.
注意模板的特异性依赖于视觉工作记忆的完整性.

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...
