Test system for language production and comprehension disorders assisted by analyzing and discriminating brain active information

1.同时记录正常人和精神分裂症患者的句子语音和言语相关电位数据，并将言语数据应用于两分检测任务中，测量ANSEs、反应时和诱发电位。识别出句子语音的关键点，包括辅音爆发的起始时间、语音的起止/偏移时间和共振峰的转换，用于语音和EEG之间的交叉相关分析。3.句子语音的光盘文件以及通过在两个不同但具有相同句法结构的不同句子之间互换短语、单词、音节等在不同水平上产生语境影响的视觉文本材料。用于编辑和呈现视觉文本数据的图形显示器被附加到具有上述程序的在线测量和处理脑电系统，以使得能够在图形显示器上编辑句子语音数据以及呈现视觉文本刺激。在辅助系统中增加了图形显示的可选帧记忆，用于分析和识别大脑活动信息，将系统性能扩展到非语言和语言认知数据处理。该系统用于正常人和精神病人，特别是有语言产生和理解障碍的精神分裂症患者的临床实验，通过听觉和视觉呈现来检查言语和非言语任务中的临床问题。通过临床诊断实验，完成了测试语言产生和理解障碍的辅助系统，并将系统获得的数据与文件中过去的数据进行了比较。进一步的临床实验需要更高的认知任务，并从脑理论的角度对系统进行评估。

1. Data of sentence speech and the speech-related potentials were recorded simul- taneously for normals as well as schizophrenics to apply verbal data on dichotic detection tasks in which ansers, reaction times and evoked potentials were measur- ed.2. Some critical points on the sentence speech including initiations of consonant bursts, voice onset/offset times and formant transitions were identified for cross- correlational analysis between speech and the EEGs.3.Disk files of sentence speech as well as visual text materials with context effects at various levels made by interchanging phrases, words, syllables, etc. between two different sentences but with the same syntactiv structure.4. The graphic display for editing as well as presenting visual text data was attached to the on-line system of measuring and processing EEGs with the above pro- grams to make it possible to edit sentence speech data on the graphic display as well as to present visual text stimuli.5. The opptional frame memory for the graphic display was added to the assist system for analyzing and discriminating brain active information for exphanding the system performance up to nonverbal as well as verbal congnitive data processing.6. The system was used in clinical experiments on normals as well as psychiatric patients, especially schizophrenics with language production and comprehension dis- orders to check clinical problems in verbal and nonverbal tasks by auditory as well as visual presentation.7. The assist system for testing language production and comprehension disorders was completed through clinical diagnostic experiments in which the data obtained by the system were compared with the past data in the files.Further clinical experiments with more higher cognitive tgasks are necessary as well as some system evaluation from the viewpoint of brain theory.
