双语功能研究中的一个关键问题是，两种已知的语言是否在任何时候都是活跃的，或者当双语个体被调到另一种语言时，一种语言是否可以被选择性地停用。心理语言学和神经科学的调查提供了不一致的数据，关于两种语言的语义激活水平，即使是在高度熟练的双语者。在本研究中，高度熟练的，早期的威尔士/英语双语者的话，在他们的语言，并要求在一种语言的话，而忽视其他单词的单词长度的决定。参与者没有被明确地告知词流的组织成对操纵（a）语义相关性，（B）语言的总理和（c）语言的目标在一个完全平衡的二乘二乘二的设计。我们观察到显着的语义启动的英语和威尔士语的目标词，无论是积极的语言，并独立的性能在低级别的字母计数任务。我们的结论是，访问的书面文字的含义是自动在两种语言中，即使流利的双语成年人被指示无视他们的语言之一的话。(C)2009爱思唯尔公司All rights reserved.
A key question in the study of bilingual functioning is whether both the languages known are active at all times or whether one language can be selectively inactivated when bilingual individuals are tuned to the other language. Psycholinguistic and neuroscientific investigations have provided inconsistent data regarding the level of semantic activation of the two languages, even in the case of highly proficient bilinguals. In the present study, highly proficient, early Welsh/English bilinguals were presented with words in both their languages and were required to make word length decisions on words in one language while disregarding words in the other. Participants were not explicitly told about the organization of the word stream in pairs manipulating (a) semantic relatedness, (b) language of the prime and (c) language of the target in a fully counterbalanced two-by-two-by-two design. We observed significant semantic priming for both English and Welsh target words, irrespective of the active language, and independent of performance in the low-level letter counting task. We conclude that accessing the meaning of a written word is automatic in the two languages even when fluent bilingual adults are instructed to disregard words in one of their languages.
