本研究从序列位置效应的角度探讨了双语者第一语言和第二语言自由回忆成绩的内在机制。在自由回忆任务中，一个典型的表现模式遵循一个U形的序列位置曲线，其中来自列表开头的项目（首因效应）和来自列表末尾的项目（新近效应）比来自列表中间的项目回忆得更准确。本研究对比了韩英双语者L1和L2自由回忆任务中的序列位置效应，并考察了独立工作记忆（WM）测量与双语者两种语言中序列位置效应之间的关系。结果表明，前近因效应（首位和中间）在L1比L2，但在两种语言中的近因效应相似。一个密切的关联，观察WM和回忆性能在前近区域的L1，但不是在L2。总之，这些研究结果表明，语言知识约束双语者的自由回忆的表现，但只在前近区域。
In this study, we examined mechanisms that underlie free-recall performance in bilinguals’ first language (L1) and second language (L2) through the prism of serial-position effects. On free-recall tasks, a typical pattern of performance follows a U-shaped serial-position curve, where items from the beginning of the list (the primacy effect) and items from the end of the list (the recency effect) are recalled with higher accuracy than items from the middle of the list. The present study contrasted serial-position effects on the free-recall task in Korean-English bilinguals’ L1 vs. L2 and examined the relationship between an independent working memory (WM) measure and serial-position effects in bilinguals’ two languages. Results revealed stronger pre-recency (primacy and middle) effects in L1 than in L2, but similar recency effects in the two languages. A close association was observed between WM and recall performance in the pre-recency region in the L1 but not in the L2. Together, these findings suggest that linguistic knowledge constrains free-recall performance in bilinguals, but only in the pre-recency region.
