概括
人们学会将眼睛的运动指向视觉信息的区域, 这会影响信心,但不会影响准确性.
科学领域:
- 认知神经科学
- 视觉运动研究
- 决策科学
背景情况:
- 眼睛的方向受到情感奖励的影响.
- 非情感信息价值对眼运动决策的影响尚不清楚.
研究的目的:
- 调查是否信息价值,独立于情感线索,可以塑造眼睛运动的决定.
- 探索学习偏好,感知表现和元认知信心之间的关系.
主要方法:
- 参与者执行了一个感知判断任务,其中saccade目标的信息可用性是概率性的.
- 通过观察眼睛的方向偏好来测量隐性偏差.
- 记录了萨卡德延迟,峰值速度,感知精度和信心评级.
主要成果:
- 参与者形成了隐含的偏见,
- 对非首选区域的萨卡德延迟时间更长,反映了奖励学习模式.
- 感知精度和冲动峰值速度没有受到影响; 偏好的区域的信心更高.
结论:
- 信息价值可以隐式学习以指导眼动,类似于奖励学习.
- 主观信心可以与学习的偏好联系在一起,而不会改变感知表现.
- 视觉运动决策和感知后判断的信心是由信息价值所塑造的,

01:25Factors Affecting Perception
1.8K
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.

01:08The Availability Heuristic
6.4K
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):
