Face memory is worse for races other than one's own, in part because other-race faces are less holistically processed. Both experiential factors and social factors have been suggested as reasons for this other-race effect. Direct measures of holistic processing for race and a non-racial category in faces have never been employed, making it difficult to establish how experience and group membership interact. This study is the first to directly explore holistic processing of own-race and other-race faces, also classed by a non-racial category (university affiliation). Using a crossover design, White undergraduates (in Australia) completed the part-whole task for White (American) and Black South African faces attributed to the University of Western Sydney (own) and University of Sydney (other). Black South African undergraduates completed the same task for White and Black South African faces attributed to the University of Cape Town (own) and Stellenbosch University (other). It was hypothesised that own-race faces would be processed more holistically than other-race faces and that own-university faces would be processed more holistically than other-university faces. Results showed a significant effect of race for White participants (White faces were matched more accurately than Black faces), and wholes were matched more accurately than parts, suggesting holistic processing, but only for White faces. No effect of university was found. Black South African participants, who have more experience with other-race faces, processed wholes better than parts irrespective of race and university category. Overall, results suggest that experiential factors of race outweigh any effects of a non-racial shared group membership. The quality of experience for the named populations, stimuli presentation, and degree of individuation are discussed.
对自己所属种族以外的其他种族面孔的记忆较差,部分原因是其他种族面孔的整体加工较少。经验因素和社会因素都被认为是产生这种其他种族效应的原因。从未采用过对面孔中种族和非种族类别进行整体加工的直接测量方法,因此很难确定经验和群体成员身份是如何相互作用的。本研究首次直接探索了本种族和其他种族面孔的整体加工情况,这些面孔也按照非种族类别(大学所属)进行了分类。采用交叉设计,白人本科生(在澳大利亚)完成了针对归属于西悉尼大学(自己所属)和悉尼大学(其他)的白人(美国)和南非黑人面孔的部分-整体任务。南非黑人本科生完成了针对归属于开普敦大学(自己所属)和斯泰伦博斯大学(其他)的白人和南非黑人面孔的相同任务。研究假设是,本种族面孔比其他种族面孔会得到更整体的加工,并且自己所属大学的面孔比其他大学的面孔会得到更整体的加工。结果显示,白人参与者存在显著的种族效应(白人面孔的匹配比黑人面孔更准确),并且整体的匹配比部分更准确,这表明存在整体加工,但仅针对白人面孔。未发现大学类别产生的效应。有更多与其他种族面孔接触经验的南非黑人参与者,无论种族和大学类别如何,对整体的加工都比对部分的加工更好。总体而言,结果表明种族的经验因素比非种族共享群体成员身份的任何影响都更重要。还讨论了指定人群的经验质量、刺激呈现和个体化程度。
