我们报告的两项研究调查双语者的词汇通达的结果。在研究1中，单语者在命名和字母流畅性测试中表现优于双语者，但在类别流畅性测试中表现不佳。当考虑词汇量时，大多数影响消失或减少。在研究2中，一个更大的双语组进行了研究，比较词汇量的影响，和一个更严格的版本的字母流畅性任务，以增加执行处理的参与。在这种情况下，双语者与匹配的词汇分数优于单语者的字母流畅性，和双语者与低词汇分数表现在同一水平的单语者。词汇量大小和执行控制对词汇提取任务的贡献的结果进行了讨论。(C)2007爱思唯尔有限公司保留所有权利。
We report the results of two studies investigating lexical access in bilinguals. In Study 1, monolinguals performed better than bilinguals on tests of naming and letter fluency, but not on category fluency. When vocabulary size was considered, most of the effects disappeared or were reduced. In Study 2, a larger group of bilinguals was studied to compare the effect of vocabulary size, and a more restrictive version of the letter fluency task was used to increase executive processing involvement. In this case, bilinguals with matched vocabulary scores outperformed monolinguals on letter fluency, and bilinguals with lower vocabulary scores performed at the same level as monolinguals. The results are discussed in terms of the contributions of vocabulary size and executive control to performance on lexical retrieval tasks. (C) 2007 Elsevier Ltd. All rights reserved.
