在发表三十年后，Bloom和Fischler(1980)的句子补全规范继续显示出广泛的实用性。本研究的目的是通过扩展现有的高约束、高完形概率句子数据库来扩大这一贡献。使用Bloom和Fischler建立的标准，我们构建了398个新句子，并将这些句子与原始列表中的100个句子一起展示出来，以400名参与者为样本。在提交的498个句子中，有400个符合高完形概率的标准--即由特定单个单词完成的概率为0.67或更高。在这些句子中，321句来自新的集合，另外79句来自布鲁姆和费施勒的集合。Bloom和Fischler对其高约束集的回答之间观察到了高度的对应。第二个实验利用N400事件相关电位范式为新生成的集合提供了进一步的语境约束验证。正如预期的那样，N400波幅在违反语境预期的句子中以一个词结束而不是新建立的补全标准时更大。句子补全规范在认知研究中经常被使用，这个更大的高完形概率句子数据库有望在未来许多年里对研究界有所裨益。这项研究的全套刺激和完句规范可以从http://brm.psychonomic-journals.org/content/supplemental.下载
Three decades after their publication, Bloom and Fischler's (1980) sentence completion norms continue to demonstrate widespread utility. The aim of the present study was to extend this contribution by expanding the existing database of high-constraint, high cloze probability sentences. Using the criteria established by Bloom and Fischler, we constructed 398 new sentences and presented these along with 100 sentences from their original list to be normed using a sample of 400 participants. Of the 498 sentences presented, 400 met criteria for high cloze probability-that is, .67 or higher probability of being completed by a specific single word. Of these, 321 sentences were from the new set and an additional 79 were from Bloom and Fischler's set. A high degree of correspondence was observed between responses obtained by Bloom and Fischler for their high-constraint set. A second experiment utilized an N400 event-related potential paradigm to provide further validation of the contextual constraint for the newly generated set. As expected, N400 amplitude was greater for sentences that violated contextual expectancy by ending in a word other than the newly established completion norm. Sentence completion norms are frequently used in cognitive research, and this larger database of high cloze probability sentences is expected to be of benefit to the research community for many years to come.
