摘要:

任务转换时, 如果一个刺激不仅包含当前任务的特征还包含另一任务的关联特征, 这样的刺激被称为双价刺激。双价刺激能影响个体对单价刺激的加工, 使个体对后续所有单价刺激的反应减慢, 这种现象被称为双价效应(bivalency effect)。研究者发现双价效应具有一定的普遍性和稳定性。对双价效应的理论解释主要有情境捆绑说和基于经验的预测模型。双价效应的产生与额外视觉特征的提取及自上而下的认知控制调整有关, 前者主要与颞-顶联合区的激活有关, 后者主要与背侧前扣带回以及前辅助运动区的激活相关。

关键词: 双价效应, 冲突, 认知控制, 背侧前扣带回, 认知机制

Abstract:

In task switching, a stimulus containing the features of the current task and the associated features of another task is defined as a bivalent stimulus. Exposure to bivalent stimuli affects the processing of univalent stimuli, slowing the response to all subsequent univalent stimuli. This phenomenon is called the bivalency effect. Researchers have found that the bivalency effect is generally and stably observed among various tasks. The theoretical explanation of the bivalency effect mainly comprises episodic context binding and the history-dependent predictive model. The generation of the bivalency effect is related to the extraction of additional visual features and top-down adjustment of cognitive control. The former is mainly related to activation of the temporal-parietal junction, while the latter is mainly related to activation of the dorsal anterior cingulate cortex and the pre-supplementary motor regions.

Key words: bivalency effect, conflict, cognitive control, dorsal anterior cingulate cortex, cognitive mechanism
