音高辨别障碍与句法和音调加工有关。在实验1中，我们评估了先天性失音症是否与音乐语法外显加工受损有关。对谐音和旋律语境中语法规则或不规则词尾的一致性评级进行了检查。与对照组不同，音乐参与者在两种情况下都不能明确区分规则和不规则的结尾。然而，令人惊讶的是，同时操纵音高距离并不影响音乐的音乐语法加工，他们的音乐语法加工受损与他们的音高辨别阈值无关。在实验2中，我们使用探针-音调范式评估调性感知。与对照组相比，音乐组的调性等级恢复不那么明显，而失音症患者对调性敏感性的降低也与差的音高辨别无关。这些发现支持了这样一种观点，即音乐结构是由独立于音高辨别的认知和神经资源处理的，这些资源在先天性失音症患者的明确判断中受损。
pitch discrimination impairments were associated with syntax and tonality processing. In Experiment 1, we assessed whether congenital amusia is associated with impaired explicit processing of musical syntax. Congruity ratings were examined for syntactically regular or irregular endings in harmonic and melodic contexts. Unlike controls, amusic participants failed to explicitly distinguish regular from irregular endings in both contexts. Surprisingly, however, a concurrent manipulation of pitch distance did not affect the processing of musical syntax for amusics, and their impaired music-syntactic processing was uncorrelated with their pitch discrimination thresholds. In Experiment 2, we assessed tonality perception using a probe-tone paradigm. Recovery of the tonal hierarchy was less evident for the amusic group than for the control group, and this reduced sensitivity to tonality in amusia was also unrelated to poor pitch discrimination. These findings support the view that music structure is processed by cognitive and neural resources that operate independently of pitch discrimination, and that these resources are impaired in explicit judgments for individuals with congenital amusia.
