Three patient education texts from the National Cancer Institute (NCI) were subjected to a Coh-Metrix analysis, then further analyzed to obtain Gist Inference Scores (GIS), a new measure of the likelihood that readers will make appropriate inferences about a text's bottom-line meaning. In the GIS formula, the Coh-Metrix psycholinguistic variables referential cohesion, deep cohesion, and latent semantic analysis (LSA) verb overlap increase GIS because cohesive texts that describe related actions are likely to induce gist representations. The Coh-Metrix variables word concreteness, imagability for content words, and hypernymy for nouns and verbs are negatively weighted because they tend to promote verbatim mental representations. NCI texts were modified for a cloze procedure with every tenth word replaced by a blank starting with the second sentence. Participants in two studies received all three cloze-modified texts. Fuzzy-Trace Theory suggests that people are more likely to comprehend high GIS texts "in their own words," and thus fill-the-blanks with multiple words that differ from those omitted by the cloze procedure expressing comparable meaning. In Study One, non-native English speakers appropriately filled blanks with different words at the same rate for all three texts of low-, medium-, and high-GIS. In Study Two, replicating previous findings, for high GIS texts, native English speakers filled blanks appropriately with words other than those removed significantly more often than for medium- or low-GIS texts. High GIS texts apparently afford readers more semantic and lexical flexibility, but non-native English speakers may be ill-equipped to capitalize on this characteristic of high GIS texts.
美国国家癌症研究所(NCI)的三篇患者教育文本进行了 Coh-Metrix 分析,然后进一步进行分析以获得主旨推断分数(GIS),这是一种衡量读者对文本底线含义进行适当推断的可能性的新方法。在 GIS 公式中,Coh-Metrix 心理语言学变量指代凝聚力、深度凝聚力和潜在语义分析(LSA)动词重叠增加 GIS,因为描述相关动作的凝聚力文本很可能会引起主旨表示。Coh-Metrix 变量词具体性、内容词的可想象性以及名词和动词的上下义词是负加权的,因为它们往往会促进逐字逐句的心理表示。NCI 文本经过修改,用于完形填空程序,每十个单词中就有一个从第二个句子开始的空格。两项研究的参与者都收到了所有三个完形填空修改后的文本。模糊痕迹理论表明,人们更有可能用自己的话理解高 GIS 文本,因此用与完形填空程序省略的不同单词来填空,表达相似的意思。在研究一中,非英语母语者以相同的速度,用不同的单词适当地填补了低、中、高 GIS 文本的所有三个空格。在研究二中,复制了先前的发现,对于高 GIS 文本,以英语为母语的人用不同于完形填空程序中省略的单词适当地填空的次数明显多于中或低 GIS 文本。高 GIS 文本显然为读者提供了更多的语义和词汇灵活性,但非英语母语者可能无法充分利用高 GIS 文本的这一特点。
