概括

这项研究发现,额外的歧视训练在空间判断偏差测试 (JBT) 中没有改变狗的"乐观". 在JBT中的表现可能反映了学习历史,而不仅仅是福利.

科学领域:

动物行为和动物福利科学
在动物身上进行认知偏差测试.
狗的认知研究研究狗的认知研究

背景情况:

空间判断偏差测试 (JBT) 通过测量接近模糊位置的延迟来评估动物的乐观情绪.
越来越乐观的JBT有时与更好的动物福利有关.
然而,JBT的表现也可能受到动物之前的学习经验的影响.

研究的目的:

为了调查是否额外的歧视学习试验影响狗的"乐观",以JBT测量.
为了确定JBT的表现是否反映了学习历史,独立于福利.
检查特定的学习治疗对伴侣狗随后的JBT结果的影响.

主要方法:

16只伴侣狗完成了治疗前的JBT,学习治疗和治疗后的JBT.
在JBT期间,狗被暴露在有奖励的,没有奖励的和模糊的位置.
一个实验组 (n=8) 接受了歧视训练 (触摸一只特定的手),而一个控制组 (n=8) 接受了制试验以控制丧.

主要成果:

在实验组和对照组之间,在接近延迟变化到模两可的位置方面没有发现显著差异.
额外的歧视学习试验并没有改变狗在JBT中的"乐观"水平.
这表明,在这个JBT范式中的"乐观"并没有受到特定的学习治疗的影响.

结论:

该研究的结果表明,通过JBT测量的"乐观"可能不仅仅表明福利,而且可以受到学习历史的影响.
使用的特定的歧视学习任务并没有改变这项研究中的伴侣狗在JBT中的"乐观".
需要进一步的研究来解开学习历史和福利对动物认知偏差措施的影响.

Confirmation Biases

Confirmation Biases

The confirmation bias is the tendency to focus on information that confirms our existing beliefs and ignore information that is inconsistent with our expectations.
