阈下安全启动改善非安全依恋女性的注意加工

研究采用掩蔽启动范式,结合事件相关电位技术,考察阈下安全启动在非安全依恋女性对婴儿面孔注意加工上的改善效应。行为指标上,悲伤程度评分和反应时结果均表明了安全启动的改善作用。ERP结果上,在早期注意加工阶段,阈下安全启动比中性启动诱发了依恋焦虑和依恋回避女性对婴儿面孔表情更大的N1波幅以及更优的P2潜伏期,在晚期控制注意加工相关的P3波幅上同样发现了类似的改善效应。研究结果表明阈下安全启动能够提升非安全依恋女性对婴儿面孔的知觉敏感性,改善非安全依恋女性注意加工缺陷,且这种改善效应不仅仅作用于早期注意加工阶段而且还可以扩展到个体有意识的晚期控制加工阶段。

Subliminally Security Priming Improve the Attention Processing among Females with Insecure Attachment

Using event related potentials, the present study adopted subliminal affective priming paradigm to explore the improvement effect of subliminal security priming on the attentional processing of infant facial expressions within insecurely attached females. In support of our hypothesis, behavioral results indicated that with subliminal security priming, anxiously and avoidantly attached females performed better in observing crying infant faces in terms of lower rating of sadness level and longer fixation time. ERP results showed that subliminal security priming resulted in greater N1 and P3 amplitudes, as well as a more optimal P2 latency to crying infant faces than subliminal neutral priming in anxiously and avoidantly attached females. These results suggest that the subliminal security priming significantly improved the attention processing defect in insecure attachment, especially for attenuating the defensive response of avoidantly attached females. Moreover, the improvement effect of subliminal security priming not only exhibited in the early attention processing but also extended to the later controlled attention processing.
