Information that conveys racial group membership plays a powerful role in influencing people's information processing including perceptual, memory and evaluative judgments. Yet whether own- and other-race information can differentially impact people's perceptual awareness at a preconscious level remains unclear. Employing a breaking continuous flash suppression (b-CFS) paradigm, we investigated whether compared with other-race stimuli, participants' own-race stimuli would be prioritized to gain privileged access to perceptual awareness. Across five experiments (N = 136), we firstly found that participants' own-race faces enjoyed privileged access to perceptual awareness (Experiment 1). In Experiments 2-5, we employed an associative training task to establish associations between otherwise arbitrary visual stimuli and own- vs. other-racial groups. Although otherwise arbitrary visual stimuli were prioritized to represent one's own race (vs. other-race) during the training, own- and other-race representing stimuli did not differ in their potency in entering perceptual awareness. This dissociation was further corroborated by Bayesian analyses and an internal meta-analysis. Taken together, our findings suggest that people's perceptual expertise with their own-race members' faces plays a determining role in shaping perceptual awareness. In contrast, newly learned race-representing stimuli did not influence early perceptual selection processes as indicated by the time they take to emerge into perceptual awareness.
种族群体归属信息在影响人们的信息处理方面发挥着强大的作用,包括感知、记忆和评价判断。然而,种族信息是否能够在潜意识层面上对人们的感知产生不同的影响,目前还不清楚。我们采用了一种打破连续闪光抑制(b-CFS)的范式,研究了与其他种族的刺激相比,参与者自己种族的刺激是否会优先获得进入感知的特权。在五个实验中(N=136),我们首先发现参与者自己种族的面孔优先获得了感知的特权(实验 1)。在实验 2-5 中,我们采用了一种联想训练任务,在其中将原本任意的视觉刺激与自己的种族和其他种族联系起来。尽管在训练过程中,原本任意的视觉刺激被优先用来代表一个人的自己的种族(而不是其他种族),但代表自己和其他种族的刺激在进入感知的能力上并没有差异。这一分离进一步得到了贝叶斯分析和内部元分析的支持。总的来说,我们的发现表明,人们对自己种族成员的面孔的感知专长在塑造感知方面起着决定性的作用。相比之下,新学习的种族代表刺激并不会影响早期的感知选择过程,这从它们进入感知所需的时间就可以看出。
