概括
期待高的感知负载,而不是动机,有助于排除分散注意力的因素. 这一发现对于理解复杂环境中的注意力和认知控制至关重要.
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.
- 注意力研究研究研究
背景情况:
- 干扰因素往往会吸引注意力,干扰任务.
- 感知上复杂的任务可能会减少分心干扰,但机制仍在争论中 (感知负载与主动控制).
研究的目的:
- 调查感知负载,主动控制和奖励动机在分心干扰中的作用.
- 检查负载和奖励的预期如何影响注意力设置和分散注意力的排除.
主要方法:
- 三个实验使用视觉搜索任务,具有不同的感知负载 (高,低,中等).
- 附带的任务不相关的分心器呈现.
- 在每个试验之前,线索表明了预期的感知负载和潜在的奖励.
主要成果:
- 注意力设置和感知负载的预期交互影响分散干扰的干扰.
- 干扰只有在高负载预期和高负载先后出现时才会减少.
- 奖励动机并没有调节干扰干扰,但在一个实验中改善了整体表现.
结论:
- 成功的分心排除依赖于对高感知负载的期望,而不是仅仅是动机或负载.
- 主动控制,特别是预测高负载,是管理注意力设置和忽略分心的关键.

Factors Affecting Perception
1.6K
Perception is influenced by perceptual set, context, motivation, and emotion. Perceptual set, or perceptual expectancy, refers to the tendency to perceive things in a particular way, influenced by previous experiences and expectations. This phenomenon affects the interpretation of stimuli, creating a set of mental tendencies and assumptions that impact sensory perceptions of sound, taste, touch, and sight.

Framing Effects
7.4K
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...

Schemas
11.6K
A schema is a mental construct consisting of a cluster or collection of related concepts (Bartlett, 1932). There are many different types of schemata, and they all have one thing in common: schemata are a method of organizing information that allows the brain to work more efficiently. When a schema is activated, the brain makes immediate assumptions about the person or object being observed.
