This study aims to clarify disfluency loci in a neurogenic stuttering group and to examine how the characteristics are different from a developmental stuttering group. For the study, spoken language samples were collected from 11 adults with developmental stuttering and 11 adults with neurogenic stuttering in the course of speaking tasks including reading, monologue and conversation. Using the collected samples, disfluency characteristics of the two groups were to be investigated by analyzing adaptation effect, consistency effect and frequency of disfluency occurrence according to word position, which are related to the occurrence loci of disfluency. Results of this study were as follows: First, while the neurogenic stuttering group did not show any adaptation effect, the developmental stuttering group showed the adaptation effect that the percent of disfluency word reducing as they read the same materials repeatedly. Second, there was no meaningful difference of consistency effect between the two stuttering groups. Third, the neurogenic stuttering group showed more disfluency frequency in final sounds among the word position compared to the developmental stuttering group.

Speech and language functions are highly cognitive and human-specific features. The underlying causes of normal speech and language function are believed to reside in the human brain. Developmental persistent stuttering, a speech and language disorder, has been regarded as the most challenging disorder in determining genetic causes because of the high percentage of spontaneous recovery in stutters. This mysterious characteristic hinders speech pathologists from discriminating recovered stutters from completely normal individuals. Over the last several decades, several genetic approaches have been used to identify the genetic causes of stuttering, and remarkable progress has been made in genome-wide linkage analysis followed by gene sequencing. So far, four genes, namely GNPTAB, GNPTG, NAGPA, and AP4E1, are known to cause stuttering. Furthermore, thegeneration of mouse models of stuttering and morphometry analysis has created new ways for researchers to identify brain regions that participate in human speech function and to understand the neuropathology of stuttering. In this review, we aimed to investigate previous progress, challenges, and future perspectives in understanding the genetics and neuropathology underlying persistent developmental stuttering.

본 연구는 부모의 게슈탈트적 언어중재를 통한 유창성장애인의 유창성 개선에 미치는 영향을 알아보기 위해 실시하였다. 부모의 게슈탈트적 언어중재 과정은 유창성장애인의 말더듬 행동에 대한 이해, 자각, 변화, 적응 그리고 유지단계로 실시하였다. 연구 대상은 신경학적 손상이나 다른 언어 및 발달 장애가 없는 유창성장애인 6명(여성 2명, 남성 4명)으로 하였다. 연구의 결과는 다음과 같다. 부모의 게슈탈트적 언어중재 후 유창성장애인의 말더듬 빈도는 감소하였다. 대상자 모두 비정상적인 유창성 중 단어부분 반복이 치료 전에는 가장 많이 빈도를 나타내었으나 치료 후에는 가장 적은 빈도를 나타내어 개선을 보였다. 그러므로 부모의 게슈탈트적 언어중재는 유창성장애인의 말더듬 빈도를 감소시키며 행동을 긍정적 방향으로 개선시키데 효과가 있었다.

In the process of speech therapy, fluency is acquired and speech rate increases in the process when the behavioral modification strategy, inducing speech fluency by making speech rate slower intentionally in an early stage, is applied. Therefore, the purpose of this study was to investigate the pause characteristics in slowed speech intentionally of treated stutterer. In this study, 10 developmental stutterers who had well established fluency in speech were involved. We had collected each 200 syllables sample of intentionally much slowed speech and a little slowed one in reading task. To measure the features of pause, total frequency of pauses, total durations of pauses, average duration of pauses and proportions of pause were investigated. The findings were as follows: Both the total durations and total frequency of pauses of much slowed speech were higher than that of a little slowed one. However, both the average duration and proportions of pauses of much slowed speech were not significantly higher than that of a little slowed one.

45명의 틱 증상을 보인 아동들의 임상적 양상을 검토하였고 형제순위별로 나눠 비교하였다. 성비는 14:1로 남자가 압도적으로 많았고 형제순위로는 맏이가 46.7%, 막내가 33.3%. 외동아 15.6%, 쌍생아 4.4%로 맏이가 많았다. 기질성 시사소견은 37.8%에서, 초기발달 이상은 71.1%, 가족관계의 이상이 89.9%에서 보였고 동반 증상들로는 주의력결핍 과잉운동장애 46.7%, 강박장애 17.7%, 격려불안은 24.4%, 범불안, 수면불안은 17.8%, 신체화 증상 및 아뇨가 각각 13.3%, 말더듬 8.9% 외에 분뇨, 우울증 등을 보여 총 84.4%에서 최소한 하나 이상의 동반된 문제를 가졌다. 형제별로 나눠 특징을 비교했을 때 발병 시기에서 현저한 차이를 보였는데 막내 유형은 입학과 연관된 시기에 발병율이 의미있게 높았다.(p<0.01) 쌍생아의 경우는 저 출생체중아가 환아였다. 이들 소견을 종합해볼 때 틱 및 뚜렛 장애의 발현에는 선천적 기질적 요인뿐 아니라 상당한 환경적인 요인이 작용한다고 보겠다.
