Over the last decade, there has been increasing evidence for syllabic processing during visual word recognition. If syllabic effects prove to be independent from orthographic redundancy, this would seriously challenge the ability of current computational models to account for the processing of polysyllabic words. Three experiments are presented to disentangle effects of the frequency of syllabic units and orthographic segments in lexical decision. In Experiment 1 the authors obtained an inhibitory syllable frequency effect that was unaffected by the presence or absence of a bigram trough at the syllable boundary. In Experiments 2 and 3 an inhibitory effect of initial syllable frequency but a facilitative effect of initial bigram frequency emerged when manipulating 1 of the 2 measures and controlling for the other in Spanish words starting with consonant-vowel syllables. The authors conclude that effects of syllable frequency and letter-cluster frequency are independent and arise at different processing levels of visual word recognition. Results are discussed within the framework of an interactive activation model of visual word recognition.
在过去十年中，越来越多的证据表明在视觉单词识别过程中存在音节处理。如果音节效应被证明独立于正字法冗余，这将严重挑战当前计算模型解释多音节词处理的能力。本文呈现了三个实验，以厘清词汇判断中音节单位频率和正字法片段的影响。在实验1中，作者获得了一种抑制性的音节频率效应，该效应不受音节边界处是否存在双字母低谷的影响。在实验2和3中，当操纵这两种测量方法中的一种并控制另一种时，对于以辅音-元音音节开头的西班牙语单词，出现了初始音节频率的抑制效应和初始双字母频率的促进效应。作者得出结论，音节频率和字母簇频率的效应是独立的，并且出现在视觉单词识别的不同处理水平上。本文在视觉单词识别的交互式激活模型框架内讨论了研究结果。
