项目摘要

This report describes basic research being conducted to develop an objective test for verbal cognitive functions with event-related potentials in communication handicapped persons, with special focus placed on severely and profoundly handicapped persons.The following three points were clarified by two studies carried out in the first year. (1) Various ERP components under passive task can be measured and highly applied. (2) The selection condition for the meaningful and the nonsense verbal was clarified in the examination of verbal cognition under passive task. (3) The difference between meaningful and the nonsense verbal was reflected on the N100 - LPC components of ERP.The difference was particularly pronounced in components after P300.On the basis of these results, the following points were clarified from research conducted on normal persons and on severely and profoundly handicapped persons in the second year. In normal persons it was found that N400 did not appear in meaningful verbal, but that P300 and LPC did.Conversely, P300 and LPC did not appear in the nonsense verbal, but N400 did. In addition, when severely and profoundly handicapped persons were classified into a good verbal understanding ability group and a poor ability group, it was clarified in the good ability group that N400 did not appear in meaningful verbal, but that P300 and LPC did, just as was demonstrated by normal persons; and that N400, which appeared in normal persons, did not appear in nonsense verbal. On the other hand, a distinct ERP component was not obtained in the poor ability group.These study results suggest that the verbal cognitive function can be objectively viewed in severely handicapped persons and other such people who have extremely limited means of communication by observing the behavior of N100, P200, P300, N400, and LPC components of ERP.

本报告介绍了为开发一种客观的语言认知功能测试而进行的基础研究，该测试使用了事件相关电位，特别关注了严重和深度残疾人。(1)被动任务下的各种ERP组件可以测量，并且具有高度的应用性。(2)在被动任务下的言语认知测试中阐明了有意义言语和无意义言语的选择条件。(3)有意义言语和无意义言语之间的差异反映在ERP的N100-LPC成分上，这种差异在P300以后的成分上尤为明显。根据这些结果，从第二年对正常人和严重和深度残疾人的研究中阐明了以下几点。正常人有意义言语中N400不出现，而P300和LPC出现，无意义言语中P300和LPC不出现，而N400出现。此外，当严重和深度残疾的人被分为一个良好的语言理解能力组和一个穷人的能力组，它是明确的，在良好的能力组中，N400没有出现在有意义的言语，但P300和LPC，就像正常人所证明的;和N400，出现在正常人，没有出现在无意义的言语。这些研究结果表明，通过观察ERP的N100、P200、P300、N400和LPC成分的行为，可以客观地观察严重残疾人和其他交流手段极其有限的人的言语认知功能。
