Abstract:

This study examined the amplification hypothesis in high-level visual processing by examining how salient stimuli modulate statistical summary representations (SSRs) of facial emotions and interact with individual factors. Experiment 1 tested salient stimuli’s impact on SSRs, while Experiment 2 varied their set-size and distribution across emotional valences. The results showed that salient stimuli increased bias, disrupting SSRs. Such interference occurred only with positive emotions. However, with more salient stimuli, the interference occurred for both emotional conditions which increased with their number increased. Furthermore, individual differences exist in the moderating effect of analytical thinking on interference. This study highlights a selective weighting mechanism in SSRs, where the effect of salient stimuli on SSRs is shaped by both stimulus properties and individual differences.

摘要:

为了探究放大假说在高级视觉中的适用性,本研究使用多特征刺激,详细探讨了凸显刺激在面孔情绪统计概要表征中的作用,并考察个体差异的调节效应。实验1考察了凸显刺激是否影响统计概要表征,实验2增加凸显刺激的数量后,操纵凸显刺激的分布以探讨其影响不同效价统计概要表征的具体方式。结果表明,凸显刺激的存在会导致偏差增加,表现出干扰效应;当凸显刺激较少时,仅在积极情绪条件下存在干扰效应;当凸显刺激较多时,两种情绪下均存在干扰效应,干扰效应随着集合数量的增多而增多。此外,分析思维对干扰程度的调节效应存在个体差异,在高愤怒敌意个体中起负向调节作用;在低愤怒敌意个体中起正向调节作用。研究揭示了统计概要表征中的选择性加权机制,即凸显刺激对面孔情绪统计概要表征的影响受刺激属性和个体差异的多重调节。
