选择性注意机制在情景线索效应中的作用

The effect of selective attention in contextual cueing

情景线索效应是指个体在视觉搜索过程中通过学习重复不变的情景信息提高搜索效率的现象。本文从情景线索效应相关行为特征、眼动特征及大脑神经活动等三个方面探讨了情景线索效应与选择性注意机制的交互作用,发现现有研究中存在着许多互相冲突的现象,增加了理解注意机制的难度。未来研究应结合认知神经科学技术寻找更多的实证数据,探索注意机制对情景线索效应的影响,以进一步完善情景线索效应中的注意机制理论。

The learning of repeated spatial context expedites human visual search performance, an effect termed as contextual cueing. In the presented review, we investigated the interaction between contextual cueing effects and selective attention based on behavioral, eye movements and the related brain responses to contextual cueing. The review addressed multiple conflicts findings in previous studies which increased the difficulty to understand selective attention mechanism. In order to further disclosure selective attention mechanism of contextual cueing, future study should combine standard contextual cueing paradigm with advanced neuroscience technologies to offer more physiological evidence about the influence of attention on contextual cueing effect.
