发展性面容失认症的研究经常表明，发展性面容失认症对人脸加工的影响与非人脸物体加工不同。然而，很少有人考虑这种情况是否与其他形式的知觉或感觉运动障碍有关。共病在其他发育障碍（如阅读障碍）的理论中发挥了作用，但对发育性面容失认症的研究往往集中在视觉识别障碍的性质上，尽管有证据表明广泛的神经异常可能影响其他感觉运动系统。我们研究了12名发展性面孔失认症的受试者与一组听觉测试评估音高和节奏的处理，以及语音感知和识别。总体而言，三名受试者在细音高辨别方面受损，患病率为25%，高于一般人群中估计的4%的先天性失乐症患病率。这是一种选择性缺陷，因为所有12名受试者的节律感知均未受影响。此外，两个prosopagnosic主题受损的音高歧视有完整的语音感知和识别，而其余九个主题中有两个受损的语音识别，但完整的音高感知。这些结果表明，在一些科目与发展性面容失认症，面孔识别缺陷是不是一个孤立的障碍，但与其他领域的缺陷，如听觉感知。这些缺陷可能形成一个更广泛的综合征的一部分，这可能是由于分布在不同的大脑网络的微结构异常，可能有一个共同的主题，右半球的优势。
Studies of developmental prosopagnosia have often shown that developmental prosopagnosia differentially affects human face processing over non-face object processing. However, little consideration has been given to whether this condition is associated with perceptual or sensorimotor impairments in other modalities. Comorbidities have played a role in theories of other developmental disorders such as dyslexia, but studies of developmental prosopagnosia have often focused on the nature of the visual recognition impairment despite evidence for widespread neural anomalies that might affect other sensorimotor systems. We studied 12 subjects with developmental prosopagnosia with a battery of auditory tests evaluating pitch and rhythm processing as well as voice perception and recognition. Overall, three subjects were impaired in fine pitch discrimination, a prevalence of 25% that is higher than the estimated 4% prevalence of congenital amusia in the general population. This was a selective deficit, as rhythm perception was unaffected in all 12 subjects. Furthermore, two of the three prosopagnosic subjects who were impaired in pitch discrimination had intact voice perception and recognition, while two of the remaining nine subjects had impaired voice recognition but intact pitch perception. These results indicate that, in some subjects with developmental prosopagnosia, the face recognition deficit is not an isolated impairment but is associated with deficits in other domains, such as auditory perception. These deficits may form part of a broader syndrome which could be due to distributed microstructural anomalies in various brain networks, possibly with a common theme of right hemispheric predominance.
