Although sex differences have been observed in various cognitive domains, there has been little work examining sex differences in the cognition of music. We tested the prediction that women would be better than men at recognizing familiar melodies, since memories of specific melodies are likely to be learned (at least in part) by declarative memory, which shows female advantages. Participants were 24 men and 24 women, with half musicians and half non-musicians in each group. The two groups were matched on age, education, and various measures of musical training. Participants were presented with well-known and novel melodies, and were asked to indicate their recognition of familiar melodies as rapidly as possible. The women were significantly faster than the men in responding, with a large effect size. The female advantage held across musicians and non-musicians, and across melodies with and without commonly associated lyrics, as evidenced by an absence of interactions between sex and these factors. Additionally, the results did not seem to be explained by sex differences in response biases, or in basic motor processes as tested in a control task. Though caution is warranted given that this is the first study to examine sex differences in familiar melody recognition, the results are consistent with the hypothesis motivating our prediction, namely that declarative memory underlies knowledge about music (particularly about familiar melodies), and that the female advantage at declarative memory may thus lead to female advantages in music cognition (particularly at familiar melody recognition). Additionally, the findings argue against the view that female advantages at tasks involving verbal (or verbalizable) material are due solely to a sex difference specific to the verbal domain. Further, the results may help explain previously reported cognitive commonalities between music and language: since declarative memory also underlies language, such commonalities may be partly due to a common dependence on this memory system. More generally, because declarative memory is well studied at many levels, evidence that music cognition depends on this system may lead to a powerful research program generating a wide range of novel predictions for the neurocognition of music, potentially advancing the field.
尽管在各种认知领域都观察到了性别差异,但很少有研究考察音乐认知中的性别差异。我们检验了这样一种预测,即女性在识别熟悉旋律方面会比男性表现更好,因为特定旋律的记忆很可能(至少部分地)通过陈述性记忆来学习,而陈述性记忆显示出女性优势。参与者为24名男性和24名女性,每组中一半是音乐家,一半是非音乐家。两组在年龄、教育程度和各种音乐训练指标上相匹配。向参与者呈现知名旋律和新颖旋律,并要求他们尽快指出对熟悉旋律的识别。女性的反应明显比男性快,效应量很大。无论参与者是音乐家还是非音乐家,无论旋律有无常见的关联歌词,女性的优势都存在,这一点从性别与这些因素之间不存在交互作用可以证明。此外,结果似乎无法用反应偏差的性别差异或在控制任务中测试的基本运动过程来解释。鉴于这是第一项研究熟悉旋律识别中的性别差异的研究,所以需要谨慎对待,但结果与促使我们做出预测的假设一致,即陈述性记忆是音乐知识(特别是关于熟悉旋律的知识)的基础,因此陈述性记忆方面的女性优势可能导致女性在音乐认知方面的优势(特别是在熟悉旋律识别方面)。此外,这些发现反驳了一种观点,即女性在涉及言语(或可言语化)材料的任务中的优势仅仅归因于言语领域特有的性别差异。此外,这些结果可能有助于解释先前报道的音乐与语言之间的认知共性:由于陈述性记忆也是语言的基础,这种共性可能部分归因于对这个记忆系统的共同依赖。更一般地说,因为陈述性记忆在多个层面都得到了充分研究,音乐认知依赖于这个系统的证据可能会引发一个强大的研究项目,为音乐神经认知产生广泛的新预测,有可能推动该领域的发展。
