The perception of temporal regularities is essential to synchronize to music and dance. Here, we explore the detection of isochrony in two mammal species. We trained rats (Rattus norvegicus) and humans (Homo sapiens) to discriminate sound sequences with regular intervals from sound sequences with irregular intervals using a go/no-go paradigm. We used four different tempi in the training sessions and two new tempi in the tests. We found that both rats and humans responded more to the novel regular test sequences than to the novel irregular test sequences. Differently from previous studies with birds, rats seem to have focused on the relative duration of the sounds, which means that they paid attention to global features defining the regularity of the sequences. In sum, this study suggests that detecting temporal regularities in sequences of sounds may have ancient evolutionary roots and could rely on timing mechanisms present in distantly related mammals.

区分大鼠（Rattus norvegicus）和人类（Homo sapiens）的时间规律。

时间规律的感知对于同步音乐和舞蹈至关重要。在这里，我们探讨了两种哺乳动物物种的等时性检测。我们训练了大鼠（Rattus norvegicus）和人类（Homo sapiens），使用go / no-go范式区分规则间隔的声音序列与不规则间隔的声音序列。我们在训练中使用了四种不同的节奏，在测试中使用了两种新的节奏。我们发现，大鼠和人类对新颖的常规测试序列的反应比对新颖的不规则测试序列的反应更大。与先前对鸟类的研究不同，大鼠似乎专注于声音的相对持续时间，这意味着它们关注定义序列规律性的整体特征。总共，这项研究表明，检测声音序列中的时间规律性可能具有古老的进化根源，并且可能依赖于远缘哺乳动物中存在的计时机制。（PsycINFO数据库记录（c）2019 APA，保留所有权利）。
