概括
这项研究表明,老鼠的回避行为重新出现,这是以前在负增强行为中未见过的现象. 这一发现提供了一种新的动物模型,用于理解和潜在地治疗避免和逃跑行为中复发的情况.
科学领域:
- 行为心理学 行为心理学
- 动物行为 动物行为
- 强化学习是一种强化学习.
背景情况:
- 复苏是灭绝的行为在替代行为的强化减少时的回归.
- 之前的研究主要集中在积极强化行为的复苏上.
- 逃避和逃跑行为,通常是负面强化,在临床环境中很常见,但这些行为的复苏在动物模型中仍然未被研究.
研究的目的:
- 通过使用动物模型,提供第一个证明负增强行为复苏的示例.
- 建立一个实验模型来研究回避行为的复苏.
- 扩展行为复发的基础研究,超越积极强化范式.
主要方法:

主要成果:
- 所有受试者都表现出最初灭的回避行为的复苏.
- 几只老鼠表现出持久而强大的复苏效应.
- 这项研究成功地模拟了负面强化行为的复苏.

Reinforcement
804
Positive and negative reinforcement are key concepts in operant conditioning, a learning process where the consequences of a behavior affect the likelihood of that behavior being repeated.
Positive reinforcement occurs when a behavior is followed by the presentation of a rewarding stimulus, increasing the frequency of that behavior. For example:

Instinctive Drift
614
Instinctive drift refers to the tendency of animals to revert to their innate behaviors despite repeated reinforcement. Breland and Breland demonstrated this concept in an experiment with a raccoon. The raccoon was trained to pick up two coins and place them in a container in exchange for food. Initially, the raccoon learned to associate the coins with food, making them a conditioned stimulus or a substitute for food. However, over time, the raccoon became less willing to put the coins into the...

Timing and Consequences on Behavior
343
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...

Punishment
830
Negative reinforcement and punishment are often confused but serve distinct functions in behavior modification. Reinforcement, whether positive or negative, increases the likelihood of a desired behavior, while punishment decreases it.
Punishment can be positive or negative. Positive punishment involves adding an undesirable stimulus, such as scolding, to decrease a behavior. Negative punishment involves removing a desirable stimulus, such as taking away a favorite toy, to decrease behavior....
