概括

干扰刺激可以帮助子选择更大的,延迟的奖励,而不是立即的奖励,通过作为条件刺激. 这种标志追踪行为有助于延迟满足,以获得更好的结果.

科学领域:

行为神经科学行为神经科学
动物认知动物的认知能力.

背景情况:

延迟折扣涉及选择立即较小的奖励而不是延迟更大的奖励.
干扰刺激可以通过作为条件刺激来促进选择更大的奖励.

研究的目的:

为了调查分心刺激是否与子一起在延迟折扣任务中充当条件刺激.
为了比较分心器在两个连续延迟折扣程序中的效果.

主要方法:

子被训练在两个连续的延迟折扣任务:仅红色和红绿色.
在一些试验中,分心刺激与初始较小的奖励提示同时呈现.
对分心器的反应没有被编程的后果.

主要成果:

两组子在分散注意力的刺激存在时,更频繁地等待更大的奖励.
与红绿组相比,只有红色组中的子表现出更长的等待时间.
结果支持分心因子作为受条件刺激的作用.

结论:

同时的分心刺激可以增强子的满足延迟.
干扰刺激可以作为条件刺激 (CS) 或更高阶条件刺激 (HOCS).
研究结果支持延迟折扣行为的信号跟踪假设.

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...
