Research reveals that selective attentional bias to socially negative information is a reliable characteristic of individuals with high-trait anxiety (HTA). However, for selective attentional bias across sensory channels (visual and auditory), the interaction between attentional bias type and negative face type remains unclear. In this study, we recruited 30 individuals with high- and low-trait anxiety (LTA) (15 in each group), and measured their engagement and disengagement bias indices using the cross-modal attentional-probe paradigm, and measured the occipital P1 component using a 64-channel electroencephalography system. The results showed that under the engagement condition in the HTA group, the occipital P1 amplitude of an angry face was smaller than that of a neutral face, and there also exhibited smaller attentional bias indices of angry faces in the HTA group than that of the LTA group. For the presence of disgusted faces, the attentional bias indices of the HTA group were smaller than that of the LTA group under the disengagement condition. These findings demonstrate that the selective attentional bias occurs both in the engagement and the disengagement facets within the cross modal. There is a feature of facilitated attentional engagement bias for an angry face, and a feature of promoted attentional disengagement bias for a disgusted face in HTA individuals.
研究表明，对社会负面信息的选择性注意偏向是高特质焦虑（HTA）个体的一个可靠特征。然而，对于跨感觉通道（视觉和听觉）的选择性注意偏向，注意偏向类型和负性面孔类型之间的相互作用尚不清楚。在这项研究中，我们招募了 30 名高特质焦虑（HTA）和低特质焦虑（LTA）个体（每组 15 名），并使用跨模态注意探针范式测量了他们的参与和脱离注意偏向指数，同时使用 64 通道脑电图系统测量了枕部 P1 成分。结果表明，在 HTA 组的参与条件下，愤怒面孔的枕部 P1 振幅小于中性面孔，并且 HTA 组对愤怒面孔的注意偏向指数也小于 LTA 组。对于厌恶面孔的存在，在脱离条件下，HTA 组的注意偏向指数小于 LTA 组。这些发现表明，选择性注意偏向既发生在跨模态的参与阶段，也发生在脱离阶段。在 HTA 个体中，存在对愤怒面孔的注意参与偏向促进特征，以及对厌恶面孔的注意脱离偏向促进特征。
