概括

狗的连续负对比 (SNC) 显示出不一致的结果. 一些狗表现出SNC,而另一些则没有,质疑其用于评估犬的福利.

科学领域:

动物行为和动物福利
比较心理学比较心理学

背景情况:

连续负对比 (SNC) 是一种行为现象,在奖励值后,反应减少.
SNC受情绪状态的影响,并有可能进行动物福利评估.
以前对狗 (Canis lupus familiaris) 的SNC研究产生了不一致的结果.

研究的目的:

调查SNC对于评估狗的情绪状态的适用性.
为了评估SNC在不同狗种群 (实验室,庇护所,拥有的) 的一致性.

主要方法:

在实验室,庇护所和拥有的狗中测试了奖励值反应 (每组n=12).
使用了一个拼图玩具任务,高价值和低价值的奖励轮换.
评估任务完成时间,所消耗的奖励和拼图操作.

主要成果:

收容所的狗和三只自己拥有的狗在奖励值 (SNC) 后表现下降 (移除的较少,吃的奖励较少,任务时间较长).
实验室狗和九只自有狗在奖励值后没有表现出响应减少.
在狗种群内和跨种群中观察到SNC表现的显著不一致.

结论:

在狗中SNC的不一致的表现引起了人们对其可靠性在评估犬的福利的担忧.
在它在福利评估中得到广泛应用之前,需要进一步的研究来了解影响狗狗SNC的因素.
