概括
延迟折扣没有预测实时酒精使用时存在负面后果. 然而,更的延迟折扣与自然环境中更高估计的血液酒精度有关,没有负面后果.
科学领域:
- 行为经济学是一种行为经济学.
- 药物成科学 药物成科学
- 神经科学是一个神经科学.
背景情况:
- 延迟折扣,即低未来奖励价值的倾向,与酒精使用障碍有关.
- 以前关于延迟折扣和酒精使用的研究依赖于实验室方法,但实际应用有限.
- 目前的研究研究了延迟折扣在自然环境中对实时酒精消费的预测能力.
研究的目的:
- 为了确定延迟折扣是否预测年轻成年人实时饮酒情况.
- 为了检查这种关系在存在和缺乏酒精消费的概率性的负面后果.
主要方法:
- 对206名年轻成年人 (45%为女性) 的数据进行二次分析,他们经常饮酒.
- 参与者在酒吧环境中自给饮酒之前完成了一个延迟折扣任务.
- 对于存在 (n=187) 或缺乏 (n=19) 概率性的负面后果 (例如,赔偿损失) 的程序有所不同.
主要成果:
- 在存在负面后果的情况下,延迟折扣没有显著预测估计的血液酒精度 (eBAC) 或饮料数量.
- 在没有概率性的负面后果的情况下,更急的延迟折扣与峰值eBAC有积极的关联.
结论:
- 与假设相反,延迟折扣没有预测负面后果的环境中的实时酒精使用情况.
- 初步证据表明,延迟折扣可能预测在缺乏负面后果的环境中使用酒精.
- 未来的研究应该探索如何折扣任务参数 (例如,结果类型,确定性,延迟) 影响酒精消费.

People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about...

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...
