概括

子通过长时间关注意想不到的奖励,表现出奖励预测错误. 青少年子对意想不到的奖励表现出高度的敏感性,反映了人类的发育模式.

科学领域:

认知科学认知科学
比较心理学比较心理学
神经科学是一个神经科学.

背景情况:

婴儿和动物更长时间地观察惊人的事件,表明预测和检测预测失败.

检查子中奖励预测灵敏度的寿命变化.

主要方法:

用于子开发了一种使用看时间反应的新型行为任务.
研究1:210只半自由放牧的子被测试了正误差,负误差和数控条件.
研究2: 363只子在整个生命周期中被评估对积极奖励预测错误的反应.

主要成果:

与预期的奖励相比,子更长时间地看着意想不到的大或小的奖励.
青少年子对意想不到的奖励表现出更强烈的反应.
在老化期间,在子中没有观察到奖励预测灵敏度的显著变化.

结论:

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...
