概括

人们更多地探索具有不确定的结果的刺激,即使它会减慢他们的速度. 这种注意力探索是由学习和减少未来的不确定性驱动的,而不仅仅是即时的奖励.

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.
决策决策决策决策

背景情况:

之前的经验会影响个人如何优先考虑处理和采取行动的环境信息.
注意力优先级是由与过去经验相关的不确定性调节的.

研究的目的:

调查前经验中的不确定性如何影响注意力优先级.
为了确定个人是否探索与更高结果差异相关的刺激.

主要方法:

三个实验使用视觉搜索任务,参与者获得金钱奖励.
干扰刺激信号奖励结果具有不同程度的差异 (不确定性).
对分散注意力的冲动模式的行为分析,结果差异不同.

主要成果:

与较低的结果差异相比,参与者更有可能参加与高结果差异相关的分心因素.
这种效应无论预期价值或奖励大小如何,都会持续下去.
对高方差干扰物的注意偏差在所有实验条件中都是一致的.

结论:

来自预测错误的不确定性在引导注意力探索方面发挥着关键作用.
注意优先级是由通过学习来减少未来不确定性的潜力驱动的.
这表明了学习驱动的注意力机制,而不是仅仅是最大限度地提高当前的信息获取.

High-Level and Low-Level Awareness

Controlled processes in human consciousness represent high-alert mental states where individuals deliberately focus their attention on achieving specific goals. Controlled processes can be seen in situations like mastering new technology, where a person might become so absorbed that they ignore surrounding distractions. Such processes involve selective attention, requiring one to concentrate on particular elements of experience while disregarding others. These are governed by executive...
