概括
人们高估了他们对随机事件的控制,这种偏见与奖励预期,预测错误和动机中大脑活动的改变有关. 这项研究揭示了控制错觉如何影响我们的奖励系统动态.
科学领域:
- 神经科学是一个神经科学.
- 行为经济学是一种行为经济学.
- 认知心理学 认知心理学
背景情况:
- 控制错觉是一种认知偏见,个人高估了他们对随机事件的影响.
- 这种偏见可能导致不准确的奖励概率估计,影响决策.
- 了解这种偏见的神经支对于解释人类在不确定的环境中的行为至关重要.
研究的目的:
- 研究控制错觉如何调节大脑的奖励系统.
- 探索与这种行为偏见相关的神经动态.
- 通过奖励系统的改变,提供对控制错觉的机制性理解.
主要方法:
- 参与者执行了一项行为任务,涉及随机结果的选择.

Diencephalon: Thalamus and Information Relay
1.5K
The thalamus, often called “the gateway to the cerebral cortex,” is vital in processing and directing sensory and motor signals throughout the brain. Almost all inputs destined for the cerebral cortex, except for olfactory signals, are relayed through the thalamus. The thalamus is a sophisticated relay station, channeling information from various brain regions to the cerebral cortex, as well as a filter, prioritizing certain signals over others based on current physiological...

Timing and Consequences on Behavior
84
In operant conditioning, the timing of reinforcement is crucial. For animals like rats and cats, immediate reinforcement (within a few seconds) is much more effective than delayed reinforcement. For example, a food reward for a rat needs to follow within 30 seconds of pressing a bar to be effective.
Humans, however, can respond to delayed reinforcers. We often make decisions between immediate small rewards and delayed larger rewards. This ability to delay gratification is a significant...
