The objective of this study was to develop a framework for investigating the roles of neural coding and cognition in speech perception.
N1 and P3 auditory evoked potentials, QuickSIN speech understanding scores, and the Digit Symbol Coding cognitive test results were used to test the accuracy of either a compensatory processing model or serial processing model.
The current dataset demonstrated that neither the compensatory nor the serial processing model were well supported. An additive processing model may best represent the relationships in these data.
With the outcome measures used in this study, it is apparent that an additive processing model, where exogenous neural coding and higher order cognition contribute independently, best describes the effects of neural coding and cognition on speech perception. Further testing with additional outcome measures and a larger number of subjects is needed to confirm and further clarify the relationships between these processing domains.
本研究旨在构建一个框架，以探究神经编码和认知在言语感知中的作用。
采用 N1 和 P3 听觉诱发电位、QuickSIN 言语理解评分和数字符号编码认知测验结果，以检验补偿处理模型或序列处理模型的准确性。
当前数据集表明，补偿处理模型和序列处理模型都没有得到很好的支持。相加处理模型可能最能代表这些数据中的关系。
使用本研究中的测量指标，显然，一个相加处理模型，其中外源性神经编码和更高阶认知独立贡献，最能描述神经编码和认知对言语感知的影响。需要进一步的测试，使用额外的测量指标和更多的受试者，以确认并进一步阐明这些处理领域之间的关系。
