摘要

先前的研究表明,当受到罕见目标气味的挑战时,犬类的搜索行为和表现会下降。本研究的目的是评估通过明确训练狗逐渐减少目标气味的时间表,是否可以在低目标气味流行率的情况下保持表现。在实验1中,9只对照犬以90%的目标患病率进行训练。九只实验犬以10%的增量逐渐降低的患病率进行训练,直到达到20%的患病率;85%的检测准确率。两组均在10%的目标气味流行率的操作环境中进行了测试。与对照犬相比,实验犬在操作环境中具有更高的准确性、命中率和更短的搜索延迟。在实验2中,23只操作犬被挑战,目标频率为10%,准确率为67%。然后,对照犬以90%的目标频率进行训练,而实验犬的目标频率从90%逐渐降低到20%。以10%、5%和0%的目标频率对这些狗进行再攻击。实验犬的表现优于对照犬(93%对82%的准确率),突出了对不常见目标进行明确训练的效果。

Part, III: Increasing odor detection performance after training with progressively leaner schedules of odor prevalence

Prior work has demonstrated canine search behavior and performance declines when challenged with infrequent target odors. The purpose of this study was to evaluate whether performance could be maintained in a low target odor prevalence context by explicitly training dogs through progressively leaner target odor schedules. In Experiment 1, nine control dogs were trained at 90% target prevalence rate. Nine experimental dogs were trained with progressively lower prevalence rates in 10% increments until reaching 20% prevalence with > 85% detection accuracy in the training context. Both groups were tested in the operational context at a 10% target odor prevalence. Experimental dogs had higher accuracy, hit percentage, and shorter search latency in the operational context compared with control dogs. In Experiment 2, twenty-three operational dogs were challenged with a target frequency of 10%, which resulted in 67% accuracy. Control dogs were then trained with 90% target frequency, whereas experimental dogs received a progressively decreasing target rate from 90% to 20%. The dogs were rechallenged with target frequencies of 10, 5, and 0%. Experimental dogs outperformed control dogs (93% vs. 82% accuracy) highlighting the effect of explicit training for infrequent targets.
