Abstract In Hebrew, as in other Semitic languages, most words are formed in a non-concatenated way, with a root morpheme embedded in a word-pattern morpheme consisting of only vowels or vowels plus consonants. Previous research on visual word recognition in Hebrew has revealed a robust morphological root-priming effect, with word recognition facilitated by the prior sub-perceptual presentation of the root morpheme, along with a less stable and more fragile word-pattern priming effect, particularly in the nominal system. These findings support the theory that morphological principles govern lexical access, with the root morpheme as a main organizational unit of the mental lexicon. However, less research has been done to delineate the algorithm underlying decomposition. The current study explores the importance of the natural lexical orthographic context of a complex root + pattern word structure for root extraction, using on-line measures based on tracking eye-movements in sentence reading. A series of 4 experiments using a fast-priming paradigm demonstrated that detaching the root morpheme from its lexical orthographic structure hinders the root-priming effect. Presenting the root in a non-word or a pseudo-word, that is, a non-existent combination of a real root + a real pattern did not make any difference. These results suggest that mapping the orthographic root onto its morphological mental representation depends on the orthographic context in which its letters appear. This finding constrains the role of the root in visual word-recognition, highlighting the crucial conditions for extracting it in the natural setting of reading.

非级联形态中词根提取对特定单词拼写上下文的依赖性

摘要 在希伯来语中，与其他闪族语言一样，大多数单词都是以非连接方式形成的，词根语素嵌入在仅由元音或元音加辅音组成的词型语素中。先前关于希伯来语视觉词识别的研究揭示了一种强大的词根启动效应，词根的先验亚感知呈现促进了词的识别，以及不太稳定和更脆弱的词模式启动效应，特别是在名义制度。这些发现支持了以下理论，即形态学原则控制词汇访问，词根词素是心理词汇的主要组织单位。然而，很少有研究描述分解的算法。目前的研究探索了复杂词根 + 模式词结构的自然词汇正字法上下文对词根提取的重要性，使用基于跟踪句子阅读中眼动的在线测量。使用快速启动范式的一系列 4 实验表明，将词根语素与其词汇正字法结构分离会阻碍词根启动效应。在非词或伪词中呈现词根，即真实词根+真实模式的不存在组合没有任何区别。这些结果表明，将正字词根映射到其形态心理表征上取决于其字母出现的正字法上下文。这一发现限制了词根在视觉词识别中的作用，
