A number of studies have pointed out that stuttering-like disfluencies could be the result of failures in central and linguistic processing. The goal of the present paper is to analyze if stuttering implies deficits in the lexical and phonological processing in visual word recognition. This study compares the performance of 28 children with and without stuttering in a standard lexical decision task in a transparent orthography: Spanish. Word frequency and syllable frequency were manipulated in the experimental words. Stutterers were found to be considerably slower (in their correct responses) and produced more errors than the non- stutterers (χ(1) = 36.63, p < .001, η2 = .60). There was also a facilitation effect of syllable frequency, restricted to low frequency words and only in the stutterers group (t1(10) = 3.67, p < .005; t2(36) = 3.10, p < .001). These outcomes appear to suggest that the decoding process of stutterers exhibits a deficit in the interface between the phonological-syllabic level and the word level.
多项研究指出，类似口吃的言语不流畅可能是中枢和语言处理出现故障的结果。本文的目的是分析口吃是否意味着在视觉单词识别中的词汇和语音处理存在缺陷。本研究比较了28名口吃儿童和非口吃儿童在一种透明正字法（西班牙语）的标准词汇判断任务中的表现。实验单词中对词频和音节频率进行了操控。结果发现，口吃者（在正确反应中）的速度明显较慢，且比非口吃者产生更多错误（χ(1) = 36.63，p <.001，η2 =.60）。音节频率也有促进作用，仅限于低频词且仅在口吃者组中出现（t1(10) = 3.67，p <.005；t2(36) = 3.10，p <.001）。这些结果似乎表明，口吃者的解码过程在音素 - 音节层面和单词层面之间的接口处存在缺陷。
