摘　　要：本研究探讨被动与主动语码切换过程中的语码切换代价及抑制控制的作用。该实验以阿拉伯数字为实验材料,随机选取高校汉-英双语大学生为被试,要求被试完成数字命名任务。结果表明,被动语码切换过程存在语码切换代价且代价对称,这一现象既可以用特定语言选择假说解释,也可以用抑制控制模型来解释,但未能直接支持抑制控制真正参与被动语码切换,有待进一步研究;主动语码切换过程中,目标语言为汉语时存在语码切换代价,而目标语言为英语时不存在语码切换代价,可能是抑制控制机制与词汇选择策略共同参与的结果。To investigate the role of inhibition control in mandatory and voluntary language switching,thirty-one Chinese-English bilingual college students participated in the numerical naming tasks.The results showed that there was a symmetric language switching cost in the mandatory language switching which could be explained by the Language-specific Selection Hypothesis or Inhibition Control Model.However,these findings could not directly support that the top-down inhibition control exactly took part in the mandatory language switching,more evidence needs to be provided by further studies.While in the voluntary language switching,language switching cost only existed in the L2-L1 trials but not in the L1-L2 trails,suggesting that the inhibition control mechanism and lexical selection strategy worked together in the voluntary language switching.

关 键 词：语码切换代价 主动语码切换 被动语码切换 抑制控制
