The main purpose of this study is to investigate guessing in the Yes/No (YN) format vocabulary test. One-hundred-and-five university students took a YN test, a translation task and a multiple-choice vocabulary size test (MC VST). With matched lexical properties between the real words and the pseudowords, pseudowords could index guessing in the YN test as correlations between false alarms and real word guessing were high (> .80). This finding provides important validity evidence for correction formulas that employ false alarm information to adjust the YN test scores. Another important finding is that the neighborhood size of pseudowords was related to false alarm rates, which has useful implications for the designing of future YN tests. Finally, the corrected scores of the YN test correlated highly (> .70) with those of the translation task. In comparison, correlations between the YN corrected scores and the MC VST scores were lower, indicating a difference in guessing between the two tests.

是/否格式词汇测试中的伪词和猜测

本研究的主要目的是调查是/否 (YN) 格式词汇测试中的猜测。一百五名大学生参加了 YN 测试、翻译任务和多项选择词汇量测试 (MC VST)。由于真实词和伪词之间匹配的词汇特性，伪词可以在 YN 测试中索引猜测，因为误报和真实词猜测之间的相关性很高 (> .80)。这一发现为使用误报信息来调整 YN 测试分数的校正公式提供了重要的有效性证据。另一个重要发现是，伪词的邻域大小与误报率有关，这对未来 YN 测试的设计具有重要意义。最后，YN 测试的校正分数与翻译任务的分数高度相关（> .70）。
