成人吃音者の吃音症状は統語的要因と音韻的要因の2つの言語的要因によって引き起こされることが分かっている．本研究では，音読時の行動学的指標である眼球運動と脳活動の指標であるEEGを利用し，成人吃音者と健常者の言語処理の言語認知過程（研究目的Ⅰ）と神経生理学過程（研究目的Ⅱ）を比較し，吃音の言語的要因を解明する．今年度は，中国人成人の吃音者と健常者を対象に，音読の行動学的実験を実施した．具体的には，言語処理の困難のない単純文と言語処理の困難がある複雑文（単語の音韻，字形，および語彙を制御した文）を作成し，音読実験を行った．眼球運動の指標を統計的に分析し，行動学的な解析が行った．研究目的Ⅰにおいて，以下の5つの結果と2つの推論を得た．結果①は，吃音者は簡単な文を音読する際に，健常者よりも長い読み時間が必要であり，その原因は，吃音者の注視点の持続時間が健常者よりも短い一方で注視回数が多いためである．結果②は，吃音者が単語の音節の長さが長くなると，注視の回数も有意に増加し，言語処理の負荷も増加する傾向がある．結果③は，同じ書き方で発音が異なる単語（同形異音語）を置き換えて作成した複雑な文の場合，その単語の言語処理には有意な差が見られなかった．結果④は，同じ発音で書き方が異なる単語（同音異形語）を置き換えて作成した複雑な文の場合，その単語の言語処理には有意な差が見られている．結果⑤は，同じ発音と書き方で意味が異なる単語（同音同形異義語）を置き換えて作成した複雑な文の場合，その単語の言語処理には有意な差が見られている．推論としては，①成人吃音者は健常者とは異なるリーディングストラテジーを使用している．②成人吃音者の言語処理において，文字の形と語彙の処理プロセスは，健常者と比較して有意に異なることがある．これらの結果を整理し，再検討を行い，成人吃音者の言語認知過程をモデル化する予定がある．

The cause of the symptoms in adults who eat music is due to the need for sound because of the need for speech. This study is related to the use of motor motor indicators, eye movements, eyeball movements, and EEG. For adults who eat sound, they learn the process of speech learning (purpose Ⅰ) the physiological process of speech (purpose Ⅱ), and the process of speech is compared, and those who eat sound should be understood. This year, Chinese adults listen to the sound, the normal, the normal, the sound and the kinesiology. The words are difficult to understand, the words are written, the words are written, the words are made, and the words are read. Eye movement refers to the statistical analysis of statistics and the analysis of kinetics. the purpose of the study is to compare the results in the following five years, and the results in the following five years have been successful. Those who listen to the sound do not listen to the sound, those who are healthy do not worry about the necessary time, the reason, and those who eat the note note that the normal person pays attention to the number of responses. As a result, at the end of the second day, those who listen to the sound will pay attention to the long-term performance of the sound, and note that the number of responses is intended to increase the number of responses. In the end, we made a copy of the text in the same way as the sound of the homophony. In result 4, we made a copy of the text in the same way as the sound of the homophone. In the end, the homonym means that the homophone means to make a copy of the text and to make a copy of the text. In the end, in the end, the homophones mean that the homophones mean that they are not allowed to make a copy of the text. 1. For adults who eat music, those who are healthy do not know what to do. For adults who eat music, they do not know what to say. For those who eat music, they do not know what to say. The words are written in the form of words, and the words are in the form of words. People who are normal are not interested in learning the meaning of music. The results of the results are sorted out, and then the results are sorted out, and then the adults are told that they know that the process is determined.
