Comparative studies of cognitive and behavioral characteristics in dogs and cats

本研究探讨了狗和猫的行为/认知特征和驯化对其的影响。在行为特征及其遗传基础方面，我们发现雄激素受体的多态性与猫的社会性有关，就像在狗中一样。关于认知特征，已经显示了以下可能性：狗主要在左半球处理人类的声音;人类的目光接触在狗的品种之间存在差异;猫区分主人的声音和其他人的声音，主人声音的情感状态，自己的名字和其他单词，以及主人的注意力状态。为了阐明系统发育的变化，我们研究了狗和猫的近亲和其他驯化物种及其亲属。狼有打哈欠传染的能力。在狮子中，亲和行为维持了友好的关系，但它们并不和解。斑马的群体运动主要由成年个体领导。

This study investigates the behavioral/cognitive characteristics and effects of domestication on them in dogs and cats. About behavioral characteristics and its genetic basis, we have shown that the polymorphism in androgen receptor related to sociality in cats, as shown in dogs. About cognitive characteristics, the following possibilities have been shown: dogs mainly process human voices in left hemisphere; eye contact for humans differs among dog breeds; cats discriminate owner's voice from others' voices, emotional states of owner's voice, their own names from other words, and owners' attention states. To clarify the phylogenetic changes, we studied the close relatives of dogs and cats and the other domesticated species and its relatives. Wolves have the capacity to yawn contagiously. In lions, affiliative behavior maintains the amicable relationship, but they do not reconcile. Zebras' group moving is mainly led by adult individuals.
