概括
练习自我控制会放大奖励反应能力,由一个更大的神经标志物称为奖励积极性 (RewP) 表示. 这种效应是普遍的,适用于个人和慈善奖励.
科学领域:
- 神经科学是一个神经科学.
- 心理学 心理学 心理学
- 认知科学 认知科学
背景情况:
- 奖励反应性假设表明,自我控制是厌恶的,导致增加寻求奖励的行为,以恢复积极的基线.
- 努力的自我控制以前与更高的奖励反应能力有关.
研究的目的:
- 为了研究练习自我控制是否会增强奖励反应的神经标记,奖励积极性 (RewP).
- 为了检查这种增强是否不同于享乐 (个人) 和eudaimonic (慈善) 奖励.
主要方法:
- 114名参与者完成了一项Stroop任务,涉及需要自我控制的条件 (不一致的试验) 和不一致的条件 (一致的试验).
- 脑电图 (EEG) 记录了神经活动,特别是奖励积极性 (RewP) 在获得快乐或eudaimonic奖励的机会期间.
- 参与者有机会为自己 (享乐) 或慈善机构 (eudaimonic) 赢得钱.
主要成果:
- 在自我控制运动后观察到更大的RewP,与没有自我控制运动时相比.
- 与会者在享乐奖励方面表现出显著更大的 RewP,与eudaimonic奖励相比.
- 在RewP上没有发现自我控制条件和奖励类型之间的相互作用,这表明域一般效应.
结论:
- 这些发现支持奖励响应性假设,通过证明一种神经生理机制,自我控制增加奖励响应性.
- 自制增强了奖励积极性 (RewP) 以一种不特定于奖励类型 (享乐或eudaimonic) 的方式.
- 这项研究为了解自我控制如何影响奖励处理和动机提供了神经基础.

Self-Discrepancy Theory
18.3K
One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

Stress prevention and management are crucial for maintaining well-being and building resilience. Techniques to manage stress include cultivating qualities like conscientiousness, a sense of personal control, and self-efficacy. Each of these traits significantly reduces stress and promotes healthier lifestyle choices and outcomes.

Timing and Consequences on Behavior
77
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...

Self-Presentation: Self-Monitoring and Self-Handicapping
38.8K
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...

Optimal Arousal Theory
124
The optimal arousal theory suggests that performance is maximized when an individual experiences a moderate level of arousal. This theory is closely tied to the Yerkes-Dodson law, which illustrates an inverted U-shaped relationship between arousal and performance. The law, formulated by psychologists Robert Yerkes and John Dodson, implies an ideal arousal level for optimal performance, and deviations from this level can lead to declines in effectiveness.

Incentive Theory: Pull Theory of Motivation
357
Incentive theory, or the "pull theory" of motivation, suggests that external rewards primarily drive behavior. Individuals are motivated to engage in activities when they anticipate a desirable outcome. This is why people often work hard for promotions or study intensively to achieve high grades. These incentives can be tangible, physical rewards such as money or promotions, or intangible, non-physical rewards like praise and social recognition.
