概括
货币和社会奖励任务激活类似的神经反应,通过奖励积极性 (RewP) 和脑波活动来衡量. 任务设计和奖励类型影响这些神经反应在不同任务中的相关性.
科学领域:
- 神经科学是一个神经科学.
- 认知心理学 认知心理学
- 社会神经科学是一种社会神经科学.
背景情况:
- 对奖励的神经反应通常使用货币任务来研究.
- 对社会奖励日益增长的兴趣需要修改任务设计.
- 了解任务设计和奖励类型的影响对于精神病理学研究至关重要.
研究的目的:
- 研究神经对金钱和社会奖励的反应.
- 为了比较不同奖励任务的脑电图 (EEG) 测量.
- 检查任务相似性对神经反应相关性的影响.
主要方法:
- 303名18岁的学生完成了一项货币门任务和两个社会任务 (社会门,岛屿逃生).
- 电脑电图 (EEG) 记录了奖励阳性 (RewP),三角形和活动.

01:24Reinforcement 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.

01:08Timing 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 factor...
