背景情况:
- 果幼虫是研究先天性和简单的学习行为的一个有价值的模型,因为它们的神经元数量减少了.
- 幼虫大脑的电子显微镜重建揭示了以前没有特征的突触连接,特别是在体中.
- 了解这些神经回路对于理解昆虫的关联性学习至关重要.
研究的目的:
- 在更复杂的学习任务中调查Drosophila幼虫的认知能力.
- 为了确定幼虫是否表现出有条件的抑制,感官预先调节和二次调节.
- 探索幼虫和成年Drosophila之间的学习能力差异的潜在原因.
主要方法:
- 在Drosophila幼虫上进行了行为实验,使用三个不同的学习任务.
- 这些任务旨在评估比以前研究的更复杂的认知能力.

Real-World Application of Classical Conditioning
545
Classical conditioning not only includes the initial pairing of stimuli but also extends to more complex forms, such as higher-order conditioning. Higher-order conditioning involves creating associations beyond the primary conditioned stimulus, resulting in a chain of conditioned responses.
Higher-order, or second-order, conditioning occurs when a neutral stimulus becomes associated with an already established conditioned stimulus through repeated pairings. For instance, if a dog has been...

Instinctive Drift
208
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...
