Abstract：
Recent advances in the field of canine neuro-cognition allow for the non-invasive research of brain mechanisms in family dogs. Considering the striking similarities between dog\'s and human (infant)\'s socio-cognition at the behavioural level, both similarities and differences in neural background can be of particular relevance. The current study investigates brain responses of n = 17 family dogs to human and conspecific emotional vocalizations using a fully non-invasive event-related potential (ERP) paradigm. We found that similarly to humans, dogs show a differential ERP response depending on the species of the caller, demonstrated by a more positive ERP response to human vocalizations compared to dog vocalizations in a time window between 250 and 650 ms after stimulus onset. A later time window between 800 and 900 ms also revealed a valence-sensitive ERP response in interaction with the species of the caller. Our results are, to our knowledge, the first ERP evidence to show the species sensitivity of vocal neural processing in dogs along with indications of valence sensitive processes in later post-stimulus time periods.
摘要：
犬神经认知领域的最新进展允许对家庭犬的脑机制进行非侵入性研究。考虑到狗和人类（婴儿）在行为层面的社会认知之间的惊人相似性，神经背景的异同可以是特别相关的。当前的研究使用完全非侵入性事件相关电位（ERP）范式调查了n=17只家庭犬对人类和特定情绪发声的大脑反应。我们发现类似于人类，狗表现出不同的ERP反应，这取决于呼叫者的种类，在刺激发作后250至650ms的时间窗口内，与狗的发声相比，ERP对人类发声的反应更为积极。在800到900ms之间的稍后时间窗口也显示了与呼叫者物种相互作用的效价敏感的ERP响应。我们的结果是,根据我们的知识，第一个ERP证据显示了狗的声音神经处理的物种敏感性，以及刺激后后期的效价敏感过程的迹象。
