概括

这项研究没有发现大脑活动表明奖励节能行为,如坐着. 然而,在行为上,人们更喜欢不那么努力的选择,支持尽量减少努力的理论.

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.
认知科学认知科学

背景情况:

了解决策的神经基础,特别是在能源支出方面,至关重要.
强化学习模型解释了奖励预测错误如何驱动行为重复.
尽量减少努力的理论提出一种偏好,要求较少的行动.

研究的目的:

为了调查能耗最小化的行为是否会引起与奖励相关的大脑活动.
通过强化学习来确定这种活动是否促进行为重复.
在节能背景下测试尽量减少努力 (TEMPA) 理论.

主要方法:

58名健康的成年人接受了脑电图 (EEG) 测试,在任务中,他们必须在坐着和站着/腰之间做出选择,以获得奖励.
量化了奖励积极性,这是由EEG衍生的奖励预测错误的衡量标准.
分析了行为选择和刺激选择概率.

主要成果:

脑电图奖励阳性试验成功区分了奖励与无奖励试验.
在坐着和站着/坐试验之间没有观察到奖励积极性的显著差异.
行为数据显示,随着时间的推移,人们更倾向于坐着,并且更有可能从站立转变为坐着,与尽量减少努力保持一致.

结论:

神经数据不支持这样的假设,即能量最小化本质上是有益的.
行为结果表明倾向于尽量减少努力,与TEMPA一致.
这些发现突出了神经奖励信号与基于努力的行为选择之间的分离.

关键词:

Reinforcement Schedules

Reinforcement Schedules

Positive reinforcement is a powerful method for teaching new behaviors to both animals and humans. B.F. Skinner demonstrated this with his experiments using rats in a Skinner box. When a rat pressed a lever, it received a food pellet. This immediate reward encouraged the rat to repeat the behavior. This method, where a reward follows every instance of the behavior, is known as continuous reinforcement. It is highly effective for establishing new behaviors quickly.
Once a behavior is learned,...

Timing and Consequences on Behavior

Timing and Consequences on Behavior

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...
