摘要之前关于双语语言转换成本的研究表明,转换成本不对称,主要由语言优势驱动,因此转换到更具优势的语言比转换到不太占优势的语言会导致更大的反应时间延迟。虽然这些研究通常依赖于转换与非转换标记的固定比例,但很明显,双语者并不是以固定的比例运作,而是沿着一个自然发生的双语模式或语境的连续体。本研究将语言转换和语言语境的概念联系起来,通过一项具有不同语境或模式的图片命名线索研究来考察语言转换成本。结果表明,转换成本取决于语言优势和语言环境,与非对称成本发现更多的单语模式和对称成本发现双语模式。语言模式和梯度抑制机制的语言选择方面的影响进行了讨论。
ABSTRACT Previous research on bilingual language switching costs has demonstrated asymmetrical switch costs, driven primarily by language dominance, such that switches into a more dominant language incur significantly greater reaction time delays than switches into a less dominant language. While such studies have generally relied on a fixed ratio of switch to nonswitch tokens, it is clear that bilinguals operate not in a fixed ratio, but along a naturally occurring bilingual continuum of modes or contexts. Bridging the concepts of language switching and language context, the current study examines language switching costs through a cued picture-naming study with variable contexts or modes. The results demonstrate that switch costs are dependent upon both language dominance and language context, with asymmetrical costs found in more monolingual modes and symmetrical costs found in bilingual modes. Implications are discussed with respect to language mode and gradient inhibitory mechanisms of language selection.
