概括
被训练来寻找猎的便的保护侦测犬有时会对其他动物保持警. 一个灭绝协议有效地减少了这些虚假警报,提高了特异性,而不会失去目标检测能力.
科学领域:
- 保护生物学 保护生物学
- 动物行为 动物行为
- 狗狗的行为和训练
背景情况:
- 侦察犬对于保护工作至关重要,但保持它们对目标物种的特异性是具有挑战性的.
- 探测犬的虚假警报可能会危及保护计划,特别是当目标很少或很难识别时.
- 在训练有素的侦察犬中纠正已确定的虚假警报的方法上存在有限的研究.
研究的目的:
- 评估基于灭绝的差异增强协议在减少两只保护检测犬的虚假警报中的有效性.
- 为了确定在训练期间经常表现出虚假警报的狗中是否可以恢复目标特异性.
- 记录作战侦察犬的训练过程和结果.
主要方法:
- 一个案例研究涉及两只受过训练来检测猎便的保护犬,在肯尼亚桑布鲁县进行.
- 实施了灭绝协议,涉及对虚假警报 (对和子便) 不提供增援.
- 训练会被录制并编码,以量化真实警报,虚假警报,错误和正确的解雇.
主要成果:
- 两只狗最初表现出"灭绝爆发",虚假警报增加,随后数量和持续时间显著下降.
- 在四个培训课程内,错误警报被大幅减少,对猎便的特异性得到了维持.
- 这些狗的准确性有所提高,在剩余的训练计划中,错误警报的数量减少.
结论:
- 灭绝协议,结合强化所需的行为,是有效的减少虚假警报在操作检测狗.
- 这项研究强调了系统训练,记录保存和检测犬样品处理协议的重要性.
- 这项研究是首次记录使用灭绝协议来解决保护侦测犬的虚假警报.

Generalization, Discrimination, and Extinction
355
Generalization, discrimination, and extinction are key concepts in operant conditioning that influence how behaviors are learned and maintained.
Generalization occurs when a behavior reinforced in one context is performed in similar situations. For instance, a student who studies diligently for calculus and receives excellent grades might apply the same study habits to psychology and history, expecting similar results. Generalization shows how learning in one setting can influence behavior in...

Principles of Classical Conditioning
399
Classical conditioning, as described by Ivan Pavlov, is a foundational concept in associative learning, where a neutral stimulus becomes capable of eliciting a conditioned response through association with an unconditioned stimulus. The process of acquisition, where this learning occurs, and the subsequent phenomena of contiguity, contingency, generalization, discrimination, extinction, and spontaneous recovery are crucial for a comprehensive understanding of classical conditioning.
