This study explores whether semantic processing in parafoveal reading in the Italian language is modulated by the perceptual and lexical features of stimuli by analyzing the results of the rapid parallel visual presentation (RPVP) paradigm experiment, which simultaneously presented two words, with one in the fovea and one in the parafovea. The words were randomly sampled from a set of semantically related and semantically unrelated pairs. The accuracy and reaction times in reading the words were measured as a function of the stimulus length and written word frequency. Fewer errors were observed in reading parafoveal words when they were semantically related to the foveal ones, and a larger semantic facilitatory effect was observed when the foveal word was highly frequent and the parafoveal word was short. Analysis of the reaction times suggests that the semantic relation between the two words sped up the naming of the foveal word when both words were short and highly frequent. Altogether, these results add further evidence in favor of the semantic processing of words in the parafovea during reading, modulated by the orthographic and lexical features of the stimuli. The results are discussed within the context of the most prominent models of word processing and eye movement controls in reading.
本研究通过分析快速并行视觉呈现（RPVP）范式实验的结果，探讨意大利语副中央凹阅读中的语义加工是否受到刺激的感知和词汇特征的调节。该实验同时呈现两个单词，一个在中央凹，一个在副中央凹。这些单词是从一组语义相关和语义不相关的词对中随机抽取的。测量阅读单词的准确性和反应时间，并将其作为刺激长度和书面单词频率的函数。当副中央凹单词与中央凹单词语义相关时，阅读副中央凹单词时观察到的错误较少；当中央凹单词高频且副中央凹单词短时，观察到更大的语义促进效应。对反应时间的分析表明，当两个单词都短时且高频时，两个单词之间的语义关系会加快中央凹单词的命名。总之，这些结果进一步证明了阅读过程中副中央凹对单词的语义加工，且受到刺激的正字法和词汇特征的调节。研究结果在阅读中最突出的单词加工和眼动控制模型的背景下进行了讨论。
