通过两个实验验证了限制性假设，即阅读中的词汇通达是基于脑旁区可获得的单词首字母信息启动的。受试者为36名视力正常的大学生。眼动进行监测，而Ss读的句子包含目标词的初始三元组（实验I）或二元组（实验II）强加了一个高或低程度的约束的词汇。与这一假设相反，高约束的单词（如侏儒）比低约束的单词（如小丑）获得更长的注视，尽管事实上，高约束的单词有一个初始字母序列共享的其他几个词在词典中。在观看条件下的固定时间的比较，有和没有parafterial字母信息表明，由于先前parafterial可用性的目标固定时间的减少量是相同的高和低约束的目标。研究结果表明，熟悉度的提高有利于词汇通达，熟悉度影响中央凹加工的效率，但不影响旁凹加工的效率。附上两个实验中使用的句子列表。(33参考）（PsycInfo数据库记录（c）2020阿帕，保留所有权利）
Tested the constraint hypothesis, which states that lexical access in reading is initiated on the basis of word-initial letter information obtainable in the parafoveal region, in 2 experiments. Ss were 36 college students with normal vision. Eye movements were monitored while Ss read sentences containing target words whose initial trigram (Exp I) or bigram (Exp II) imposed either a high or a low degree of constraint in the lexicon. In contradiction to the hypothesis, high-constraint words (eg, dwarf) received longer fixations than did low-constraint words (eg, clown), despite the fact that high-constraint words have an initial letter sequence shared by few other words in the lexicon. A comparison of fixation times in viewing conditions with and without parafoveal letter information showed that the amount of decrease in target fixation time due to prior parafoveal availability was the same for high-and low-constraint targets. It is concluded that increased familiarity of word-initial letter sequence is beneficial to lexical access and that familiarity affects the efficiency of foveal but not parafoveal processing. A list of the sentences used in the 2 experiments is appended.(33 ref)(PsycInfo Database Record (c) 2020 APA, all rights reserved)
