摘要
分别将情绪面孔图片作为线索(实验一)或靶子(实验二)呈现,利用线索-靶子范式考察了定位任务中情绪面孔加工对返回抑制的影响。结果发现:以不同情绪面孔作为线索时,返回抑制稳定出现,表现出与情绪加工的分离;而当情绪面孔作为靶子时,与中性面孔相比,情绪面孔引发的返回抑制量显著较小。该研究表明,在定位任务中,返回抑制不受线索生物性的影响,但是会受到靶子性质的影响,反映出机体在不同条件下对空间注意和情绪加工的灵活性。
In the current study, two experiments were conducted to investigate the influence of emotional faces on IOR with 90 emotion- al face pictures （positive, negative, and neutral） as the cues or the targets. Twenty participants in each experiment were instructed to complete the task of judging the location of the target. ANOVAs were conducted on reaction time for each experiment. In Experiment 1, only the main effect of cues was reliable, indica- ting IOR was a mechanism of blindness. In Experiment 2, both the main effect of cues, and the interaction of cue and target emotional valence were significant, implying the modulation of emotional faces on IOR. In summary, we found that IOR was dissociated when the emotional faces appeared in the cue location, verifying the stability of IOR. But the IOR to the neutral faces was larger than the IOR to the positive and negative faces when the faces acted as the target in the cue - target paradigm. The results indicate that IOR is not affected by the biological cues, but affected by the nature of targets.
