这项纵向研究评估了133名3岁和6岁的德国高加索婴儿。在视觉期望范式（VExP）下，研究本种族和其他种族面孔作为视觉刺激对联想学习的影响。这项研究与其他种族效应（ORE）的研究结果有关，据说这种效应在6个月大时出现。白人面孔被用作熟悉种族类别的刺激物，而非洲面孔被用作不熟悉种族类别的刺激物。两种刺激类型的婴儿在3个月时对刺激变化的反应时间（RT）无显著差异。在6个月大时，白人面孔组婴儿的RT显著下降，而非洲面孔组婴儿的RT则没有显著下降。这些结果表明，到6岁时，对其他种族和本种族面孔的处理。月数，也就是ORE发病的相关年龄，对VExP的表现有重要影响。版权所有：John Wiley & Sons， Ltd。
This longitudinal study assessed 133 Caucasian German infants at 3 and 6?months of age to investigate the influence of own-race and other-race faces as visual stimuli on association learning in the visual expectation paradigm (VExP). The study is related to the findings on the other-race-effect (ORE) which is said to emerge at 6months of age. Caucasian faces were used as stimuli of a familiar ethnic category, whereas African faces were used as stimuli of an unfamiliar ethnic category. There was no significant difference between the two stimulus classes in infants' reaction time (RT) to stimulus shifts at 3?months. At 6months of age, infants' RT decreased significantly in the Caucasian faces condition but not in the African faces condition. These results indicate that the processing of other-race versus own-race faces by the age of 6?months, which is also the relevant age for the onset of the ORE, has an important influence on the performance on the VExP.
