How attachment style affects emotion processing is tightly connected with individuals' attention bias. This experiment explored avoidant individuals' attentional engagement and attentional disengagement using a cue-target paradigm in fMRI. The experimental group consisted of 17 avoidant participants, while the control group consisted of 16 secure participants; these were identified by the Experiences in Close Relationships inventory and the Relationship Questionnaire. Each reacted to pictures of positive parent-child attachment, negative parent-child attachment, positive romantic attachment, negative romantic attachment, and neutral non-attachment. Behaviorally, avoidant individuals were slower than secure individuals in responding to emotions and their attentional disengagement effect for negative parent-child emotions was stronger than positive ones. fMRI results showed that avoidant compared to secure individuals activated more strongly in the right superior temporal gyrus, middle occipital gyrus, and the left medial frontal gyrus, middle occipital gyrus, supplementary motor area, and cingulate gyrus. They also showed stronger activation in disengaging from positive than negative emotions in the bilateral fusiform and middle occipital gyri. In conclusion, avoidant individuals could detect emotions as effective as secure individuals in attentioal engaging stages. They can disengage from positive emotions with effective cognitive resources and were harder to get rid of negative emotions with insufficient resource.
依恋风格如何影响情绪处理与个体的注意偏向紧密相关。本实验采用 fMRI 的线索-靶子范式,探讨了回避型个体的注意投入和注意脱离。实验组由 17 名回避型参与者组成,对照组由 16 名安全型参与者组成;这些参与者通过亲密关系经历量表和关系问卷进行了识别。每个人对积极的亲子依恋、消极的亲子依恋、积极的浪漫依恋、消极的浪漫依恋和中性的非依恋图片做出反应。行为上,回避型个体对情绪的反应比安全型个体慢,他们对消极亲子情绪的注意脱离效应比积极情绪强。fMRI 结果表明,与安全型个体相比,回避型个体在右侧上颞叶、中枕叶和左侧额内侧回、中枕叶、辅助运动区和扣带回的激活更强。他们还显示,在双侧梭状回和中枕叶中,从积极情绪脱离比从消极情绪脱离时的激活更强。总之,回避型个体在注意投入阶段能像安全型个体一样有效地感知情绪。他们可以用有效的认知资源从积极情绪中脱离,而用不足的资源则更难从消极情绪中脱离。
