识别情感韵律（接受性韵律）的困难可能发生在右半球损伤（RHD）之后。并不是所有的个体都能自发地恢复识别情感韵律的能力，因此需要进行行为干预。然而，在这一临床人群中缺乏基于证据的接受性味觉减退治疗研究。本研究的目的是探讨一个明确的培训协议，针对成人RHD和接受性韵律的情感韵律识别。18名成年人接受由于急性风湿性心脏病的韵律识别情感之前和之后的短期培训课程，有针对性地提出了潜在的感知和概念过程。行为障碍和病变特征进行了调查，可能影响培训效果。情感韵律识别在训练后得到改善，并且识别准确率对于伪句子与真实句子更高。知觉缺陷与最后的梗死相关，概念缺陷与额叶梗死相关，而知觉-概念缺陷的组合与颞顶和皮质下梗死相关。几个右半球腹侧流区域和途径沿着与额叶和顶叶低灌注预测训练效果。外显声学韵律情感训练提高情感韵律识别，但它可能不适合每个人。在进行韵律训练时，应考虑语言环境和损伤位置等因素。
Difficulty recognizing affective prosody (receptive aprosodia) can occur following right hemisphere damage (RHD). Not all individuals spontaneously recover their ability to recognize affective prosody, warranting behavioral intervention. However, there is a dearth of evidence-based receptive aprosodia treatment research in this clinical population. The purpose of the current study was to investigate an explicit training protocol targeting affective prosody recognition in adults with RHD and receptive aprosodia. Eighteen adults with receptive aprosodia due to acute RHD completed affective prosody recognition before and after a short training session that targeted proposed underlying perceptual and conceptual processes. Behavioral impairment and lesion characteristics were investigated as possible influences on training effectiveness. Affective prosody recognition improved following training, and recognition accuracy was higher for pseudo- vs. real-word sentences. Perceptual deficits were associated with the most posterior infarcts, conceptual deficits were associated with frontal infarcts, and a combination of perceptual-conceptual deficits were related to temporoparietal and subcortical infarcts. Several right hemisphere ventral stream regions and pathways along with frontal and parietal hypoperfusion predicted training effectiveness. Explicit acoustic-prosodic-emotion training improves affective prosody recognition, but it may not be appropriate for everyone. Factors such as linguistic context and lesion location should be considered when planning prosody training.
