强调野生灵长类动物的文化风格的说法还没有得到实验证实。这是第一个关于文化风格在物种内传播的实验研究。呼叫回放影响了绒猴在回放时间之外增加联系。我们的研究结果表明,回放引发了文化风格的暂时转变。支持对行为率组间差异的文化解释。文化差异可以通过两种主要方式来概念化:这些差异既表现为行为形式上的文化特有的质的差异,也表现为普遍行为(文化风格)组合的表现上的量的差异。尽管在野生非人灵长类动物中观察到这两种类型,但定性文化的扩散已经被广泛地实验研究,而文化风格的种内传播仍然完全未被探索。在这里,我们调查了是否可以人工产生的非人灵长类动物(Callithrix jacchus)的文化风格的高隶属关系,通过每天播放同种隶属的电话模拟附近的友好的个人。我们发现,相对于无声播放,发声播放影响猴子在播放时间之外花更多的时间进行亲和行为。这种影响是特定于从属关系的,对其他类别的影响没有影响。在所有回放完成后,这种变化没有持续到观察的最后阶段。研究结果是一致的,通过发声播放影响的文化风格的临时转变,支持存在这种概念的文化在野生灵长类动物和听觉社会传染作为一个潜在的扩散机制。这里提出的方法将允许研究人员测试关于文化风格的文化传播的假设,以及在一系列背景和物种中的潜在过程。
HighlightsClaims of cultural style in wild primates have yet to be substantiated experimentally.This is the first experimental study of within-species diffusion of cultural style.Call playback influenced marmosets to increase affiliation outside playback hours.Our findings indicate that playback initiated a temporary shift in cultural style.Supports cultural interpretation of between-group variation in behaviour rates.Cultural variation can be conceptualized in two main ways: as culture-specific qualitative differences in behavioural form, and also as quantitative variation in performance of constellations of universal behaviours (cultural style). Despite observation of both types in wild nonhuman primates, diffusion of qualitative culture has been scrutinized extensively experimentally while within-species transmission of cultural style has remained entirely unexplored. Here we investigated whether a cultural style of high affiliation could be artificially generated in a nonhuman primate (Callithrix jacchus), by daily playback of conspecific affiliative calls simulating nearby amicable individuals. We found that vocalization playback influenced monkeys to spend more time in affiliative behaviours outside playback hours, relative to silent playback. The effect was specific to affiliation, with no impact on other categories of affect. This change did not persist into the final phase of observation after all playbacks were complete. Findings are consistent with a temporary shift in cultural style effected through vocalization playback, supporting existence of this conception of culture in wild primates and indicating auditory social contagion as a potential diffusion mechanism. The method presented here will allow researchers to test hypotheses concerning cultural transmission of cultural style, and the underlying processes, across a range of contexts and species.
