男性和女性的不同，他们的皮层下诱发反应的声音。对于许多诱发反应的措施，性别差异是由一个更快的发展下降的男性听觉处理。使用频率跟随反应（FFR），诱发电位，主要反映中脑处理的刺激功能，性别差异被确定在响应的时间包络的讲话。男性与女性的反应较晚和较小的模式与跟踪语言发展和阅读能力的三个反应特征中的两个一致。因此，在这里我们分析了皮层下反应的一致性，这是语言能力的第三个显著特征。此外，虽然包络主要是低频响应，但在谐波编码中观察到最大的性别差异。为了更好地理解这些性别差异，我们将这些发现扩展到时间精细结构反应，这是偏向于高频信息。使用相同的516名参与者，如前所述，我们分析了性别对反应一致性和时间精细结构编码的影响，如减频后反应所示。我们发现，虽然男性和女性没有不同的反应一致性，有一个年龄对这一措施的影响。此外，虽然男性仍然表现出更快的谐波编码下降，幅度和宽度的性别差异较小的时间精细结构响应相比，信封的反应。这些结果表明，性别差异是不同的，至少部分，从差异的基础语言能力和发展的性别差异反映皮层下听觉处理的时间包络和声音的精细结构的差异。
Males and females differ in their subcortical evoked responses to sound. For many evoked response measures, the sex difference is driven by a faster developmental decline of auditory processing in males. Using the frequency-following response (FFR), an evoked potential that reflects predominately midbrain processing of stimulus features, sex differences were identified in the response to the temporal envelope of speech. The pattern of later and smaller responses in males versus females is consistent with two of the three response features that track with language development and reading abilities. Therefore, here we analyzed subcortical response consistency, the third distinguishing feature of language ability. Furthermore, though the envelope is primarily a low-frequency response, the greatest sex differences were observed in harmonics encoding. To better understand these sex differences, we extended these findings to the temporal fine structure response, which is biased to high-frequency information. Using the same 516 participants as previously reported, we analyzed the effect of sex across development on response consistency and the encoding of temporal fine structure, as indexed by the subtracted frequency-following response. We found that while males and females did not differ on response consistency, there was an effect of age on this measure. Moreover, while males still showed a faster decline in harmonic encoding, the magnitude and breadth of the sex differences were smaller in the temporal fine structure response compared to the envelope response. These results suggest that sex differences are distinct, at least in part, from the differences that underlie language abilities and that developmental sex differences reflect subcortical auditory processing differences of both the temporal envelope and fine structure of sounds.
