Reaction time (RT) and the N400 ERP component were measured to examine age-related differences in bilingual language processing. Although young bilinguals appear to access both languages simultaneously (i.e., non-selective access), little is known about language selection in older adults. The effect of language context on language selectivity was investigated using interlingual homographs (IH; i.e., words with identical orthography but distinct semantic features in two languages, e.g., coin meaning 'corner' in French and 'money' in English). Younger and older French/English bilinguals were presented with triplets of letter strings comprised of a language context cue, an IH, and a target word, in a lexical decision semantic priming task. RT and ERP results support non-selective language access in young adults; however, the older bilinguals used the language context cue to bias their reading of the IH. Results are discussed in terms of age-related changes in language processing and context use in bilinguals.
反应时间 (RT) 和 N400 ERP 成分被测量，以检查双语语言处理中的年龄相关差异。尽管年轻的双语者似乎可以同时访问两种语言（即非选择性访问），但对于老年人的语言选择知之甚少。使用跨语言同形词（IH；即，在两种语言中具有相同的拼写但具有不同语义特征的单词，例如，coin 在法语中表示“角落”，在英语中表示“钱”）研究了语言语境对语言选择性的影响。在词汇决策语义启动任务中，年轻和年长的法/英双语者接受了由语言语境提示、IH 和目标词组成的三字母字符串的呈现。RT 和 ERP 结果支持年轻人的非选择性语言访问；然而，年长的双语者使用语言语境提示来偏向他们对 IH 的阅读。结果根据双语者语言处理和语境使用的年龄相关变化进行了讨论。
