：之前的研究表明，本种族面孔的工作记忆 (WM) 表现优于其他种族面孔。我们重点关注存储容量和编码率来识别 WM 特征，以促进自己种族的人脸识别。我们研究了 WM 的本种族和其他种族面孔的时间动态，以分别确定存储容量和编码率对 WM 中本种族优势的贡献。在两个实验中，我们向亚洲参与者展示了亚洲人的面孔作为自己种族的面孔，而黑人面孔作为其他种族的面孔。实验1和实验2表明本方人脸的存储容量更高，实验2还表明当使用后向掩码时，本方人脸的编码率有所提高。此外，存储容量和编码率之间没有关联。这些发现表明，存储容量和编码率独立地影响 WM 中的跨种族效应。
: Previous research has shown that working memory (WM) performance for own-race faces is better than for other-race faces. We focused on the storage capacity and encoding rate to identify WM characteristics that facilitate own-race face recognition. We investigated WM ’ s temporal dynamics for own- and other-race faces to separately identify the contribution of storage capacity and encoding rate on the own-race advantage in WM. We presented Asian participants with Asian faces as own-race faces and Black faces as other-race faces in two experiments. Experiments 1 and 2 indicated a higher storage capacity for own-race faces, and Experiment 2 also indicated an increased encoding rate for own-race faces when backward masking was used. More-over, there was no association between storage capacity and encoding rate. These fi ndings suggest that both storage capacity and encoding rate independently contribute to the cross-race effect in WM.
