任务转换范式下情绪注意偏向

相对于其他信息来说,情绪信息往往会引起情绪障碍患者更多的注意并具有一种认知加工上的优先权。在注意实验中,与中性刺激相比,具有情绪意义的刺激更能吸引注意或占用注意资源从而引起注意偏向。通过转换代价和任务规则一致性效应两个指标阐述了任务转换范式下情绪障碍患者的情绪信息注意偏向加工机制,并指出这两种指标分别代表了个体在注意偏向中的两个不同的认知控制加工,为情绪障碍患者的情绪调节提供必要的依据。文中最后还指出了ERPs、f MRI新技术是未来任务转换范式下研究情绪与注意关系的新方向。

Emotional Attention Bias under the Paradigm of Task Switching

Compared with other stimuli, emotional stimuli usually result in faster and more attention, and present a cognitive processing priority. In the studies of investigating the relation of attention and emotion, emotional materials are observed to attract attention or occupy attention resource, thereby cause attention bias. The current study shows attention bias processing mechanism to emotional information in patients with emotional disorder. Two task-switching indices, Switching Cost and Task Rule Congruency Effect, which represent two distinct sets of processes, have been used so far, which can be measured simultaneously. In addition, this paper provides the necessary basis for emotional modulation. It points out the currently-adopted new technology, such as ERPs and fMRI to study the connection between emotion and attention in the future.
