概括

熊蜂表现出有限的自我控制,不一致地选择延迟的奖励而不是即时的奖励. 它们等待更好的结果的能力各不相同,为昆虫自我控制的进化提供了见解.

科学领域:

认知生态学认知生态学
动物行为动物行为

背景情况:

自制,或抵制即时的诱惑以获得未来的利益,与高级认知有关.
研究传统上侧重于大脑动物,需要研究各种物种,如昆虫,以获得进化见解.

研究的目的:

为了研究熊蜂 (Bombus terrestris) 延迟满足的能力.
探索自我控制的进化起源和生态驱动因素.

主要方法:

使用延迟维护任务,训练蜜蜂将鲜花的颜色与即时的小或延迟的大奖励联系起来.
蜜蜂经历了多重选择试验和最后的试验,无限期延长延迟.

主要成果:

熊蜂并不总是喜欢延迟的奖励而不是立即的奖励.
个人的等待时间是高度可变的,尽管有一小部分人表现出长时间的延迟.

结论:

熊蜂的自我控制似乎有限,可能受到生态因素或食策略的影响.
这些发现有助于理解不同物种自我控制的演变.

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...
