双语词汇理解切换中非目标语言加工

The Mechanism of Non-target Language Processing in Lexical Comprehension Switching

实验采用直接语音掩蔽启动范式,通过掩蔽词的有、无呈现对切换后单词的读音判断反应时产生影响,进而了解非熟练双语者双语理解切换中非目标语言加工状态。实验结果表明,无呈现掩蔽词组的反应时比有呈现组的判断反应时长;不同掩蔽词呈现时间两组中切换反应时判断不显著。实验证明无论是哪一种语言作为非目标语言,其在词汇层上均都不会被激活;双语词汇理解切换中,切换至熟练语言比切换至不熟练语言切换代价小。

Masking experiments is used in lexical decision task pronunciation. It changes the time of the adding masking word time in bilingual switching, and influences reaction time of the later word pronunciation, so as to understand the non-proficient bilinguals mechanism of non-target language in lexical comprehension switching. The results show that the masking effect is significantly different from the non-masking effect, while the presented time of masking words are not significant. The current research show that non-target language words in both languages which are in the level of lexical processing are not activated in lexical comprehension switching, and there is the switching cost in lexical comprehension switching.
