Social context affects the performance and outcomes of many animal behaviors, and mate choice is no exception. Davies et al. (2020) investigated evidence for and factors that moderate mate choice copying, a prevalent type of social influence on mate choice. This work expands on and complements our own meta-analysis (Jones and DuVal 2019) and, despite differences in analytical approaches, both studies confirmed that the phenomenon is robust and taxonomically widespread. Jones and DuVal (2019) found that females were 2.7 times more likely to mate with a male when they saw another female do so (or mate with a male of the same phenotype); Davies et al. (2020) reported a 2.83 increase in the presence of such social information in an expanded data set. Additionally, both studies detected a stronger copying effect in a sample of studies dominated by tests where females observed another female “choose” a male that they had rejected in a pretest trial (i.e., a reversal paradigm). We interpreted this finding as indicative of increased use of social information when favors “unattractive” individuals, while Davies et al. (2020) suggested that repeated testing could affect aspects of choosiness. An intriguing additional possibility is that females may change their choice “irrationally” in repeat testing (Lea and Ryan 2015). Future studies with reversal designs could test this by not exposing control females to the choice of a model female, then assessing whether their mate choices change across subsequent trails.

我将拥有她所拥有的:Davies等人的评论

社会环境会影响许多动物行为的表现和结果,伴侣的选择也不例外。Davies等。(2020)研究了适度的配偶选择复制的证据和因素,配偶选择复制是一种对配偶选择的社会影响的普遍类型。这项工作是对我们自己的荟萃分析的补充和补充(Jones and DuVal 2019),尽管分析方法存在差异,但两项研究均证实该现象是稳健的并且在分类学上广泛存在。琼斯和杜瓦尔(Jones and DuVal,2019)发现,与另一只雌性交配(或与相同表型的雄性交配)时,雌性与雄性交配的可能性是2.7倍 Davies等。(2020年)报道,在扩展的数据集中,此类社交信息的存在增加了2.83个。另外,两项研究均在以测试为主的研究样本中发现了较强的复制效果,其中女性观察到另一位女性“选择”了在预测试中被拒绝的男性(即逆转范例)。我们认为这一发现表明,当偏爱“缺乏吸引力”的个人时,社交信息的使用增加了,而Davies等人则认为。(2020)建议重复测试可能会影响选择的方面。另一个有趣的可能性是,女性在重复测试中可能会“非理性地”改变他们的选择(Lea和Ryan 2015)。未来采用逆向设计的研究可以通过不让对照雌性暴露于模型雌性的选择,然后评估其配偶选择是否在随后的试验中发生变化来测试这一点。逆向范例)。我们认为这一发现表明,当偏爱“缺乏吸引力”的个人时,社交信息的使用增加了,而Davies等人则认为。(2020)建议重复测试可能会影响选择的方面。另一个有趣的可能性是,女性在重复测试中可能会“非理性地”改变他们的选择(Lea和Ryan 2015)。未来采用逆向设计的研究可以通过不让对照雌性暴露于模型雌性的选择,然后评估其配偶选择是否在随后的试验中发生变化来测试这一点。逆向范例)。我们认为这一发现表明,当偏爱“缺乏吸引力”的个人时,社交信息的使用增加了,而Davies等人则认为。(2020)建议重复测试可能会影响选择的方面。另一个有趣的可能性是,女性在重复测试中可能会“非理性地”改变他们的选择(Lea和Ryan 2015)。未来采用逆向设计的研究可以通过不让对照雌性暴露于模型雌性的选择,然后评估其配偶选择是否在随后的试验中发生变化来测试这一点。另一个有趣的可能性是,女性在重复测试中可能会“非理性地”改变他们的选择(Lea和Ryan 2015)。未来采用逆向设计的研究可以通过不让对照雌性暴露于模型雌性的选择,然后评估其配偶选择是否在随后的试验中发生变化来测试这一点。另一个有趣的可能性是,女性在重复测试中可能会“非理性地”改变他们的选择(Lea和Ryan 2015)。未来采用逆向设计的研究可以通过不让对照雌性暴露于模型雌性的选择,然后评估其配偶选择是否在随后的试验中发生变化来测试这一点。
