概括
不相关的感官信息对决策产生不同的影响,具体取决于它的模式和任务. 听觉分心影响早期的感官处理,而视觉分心影响后来的决策阶段.
科学领域:
- 认知神经科学 认知神经科学
- 感官处理 感官处理
- 决策 - 决策 - 决策 - 决策
背景情况:
- 大脑将多感官信息整合到行为中,但不相关刺激对目标导向决策的影响仍然不太清楚.
- 了解不同的感官模式在决策过程中如何相互作用,对于解释认知过程至关重要.
研究的目的:
- 调查跨模和内模任务无关信息对视觉和听觉分类决策的影响.

The Availability Heuristic
6.0K
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):

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.

Cause and Effect

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?
