| 摘 要： | 不安全依恋者的注意偏向是指依恋焦虑和回避个体对依恋信息产生或趋近或回避的注意偏好, 这一注意偏好使得个体形成了处理与依恋对象关系的特殊认知机制：依恋回避个体偏好采用防御性机制, 倾向于回避对依恋信息的注意; 依恋焦虑个体偏好采用夸大性机制, 倾向于夸大威胁性信息, 因而会积极寻求与依恋对象的亲近。不安全依恋者注意偏向的差异主要体现在情绪信息、痛觉感受和工作记忆三个方面; 加工阶段特征主要涉及P1、N1波等代表的注意自动加工和LPP波代表的注意控制加工; 脑网络上主要包括两个子网络, 即负责情绪评估的边缘系统和负责情绪调节的以前额叶为代表的神经网络。未来研究中更应该关注刺激物的生态效度, 检验依恋系统是否激活, 不安全依恋者注意偏向的自动加工和控制加工阶段的关系, 不安全依恋者注意偏向产生的分子遗传机制以及注意偏向的跨文化研究。

| Abstract: | The attentional bias of individuals with insecure attachment refers to the fact that individuals with certain traits generate the attention of preference, attached or avoidant, responding to the attachment information, which allows individuals to form a specific cognitive mechanism dealing with the relationships with attachment figures: The avoidant individuals prefer defensive mechanisms and tend to shy away from the attachment information; the anxious individuals are in favor of exaggerated mechanisms, incline to exaggerate the threatening information, pay more attention to the threatening information and thus seek closeness to attachment figures actively. In the study of behaviors, the attentional bias of individuals with insecure attachment mainly reflects on emotional information, spacial allocation, pain sensation and working memory; about the EEG index, it mainly involves P1, N1 and LPP waves, which respectively represent automatic attention processing and controlled attention processing; on the part of brain network, it mainly includes limbic system which is responsible for the assessment of emotion and neural networks which are in charge of emotion management and represented by prefrontal cortex. Future studies should focus on ecological validity of stimuli, inspection on whether attachment system is activated or not, the relationship between automatic processing and controlled processing stages to attentional bias, the molecular genetic mechanism which results in the attentional bias of individuals with insecure attachment and the cross-culture study of attentional bias. |
