靶子与分心物不同分离条件下，工作记忆负载对Stroop干扰效应的影响
发布时间：2019-01-26 07:07
【摘要】：工作记忆负载是认知控制的重要影响因素,研究认知控制常采用Stroop冲突任务。然而关于工作记忆负载对认知控制的影响机制:是注意机制还是执行控制机制在其中起作用,研究者们没有得出一致的结论。本研究包括两个实验,实验一采用工作记忆任务+Stroop任务的双任务范式,实验结果发现基于多重资源理论,仅在靶子和分心物空间分离的Stroop任务下,工作记忆负载对Stroop干扰效应产生了影响。实验二采用2-1映射范式分离出Stroop冲突中的两类冲突——任务冲突和反应冲突。实验结果发现,工作记忆负载仅对任务冲突产生了影响。总之,多重资源理论成立的前提是Stroop任务中靶子与分心物处于空间分离状态。而当靶子与分心物处于融合状态时,工作记忆负载对Stroop干扰效应的影响是基于注意机制的。工作记忆负载对Stroop干扰效应的影响是由注意机制和执行控制机制共同起作用,并且注意机制先于执行控制机制发生。
[Abstract]:Working memory load is an important factor in cognitive control. Stroop conflict task is often used in cognitive control. However, as to the influence of working memory load on cognitive control, whether the attention mechanism or the executive control mechanism plays an important role, the researchers have not reached a consistent conclusion. This study consists of two experiments. Experiment 1 adopts the two-task paradigm of working memory task Stroop task. The experimental results show that based on the theory of multiple resources, only the Stroop task with the separation of target and distraction space is used. Working memory load has an effect on Stroop interference. In experiment 2, two kinds of conflicts in Stroop conflict, task conflict and response conflict, are separated by 2-1 mapping paradigm. The experimental results show that the working memory load only affects the task conflict. In a word, the premise of multi-resource theory is that the target and distraction are separated in space in Stroop mission. When the target and the distractor are fused, the effect of working memory load on Stroop interference is based on the attention mechanism. The effect of working memory load on Stroop interference is caused by both the attention mechanism and the executive control mechanism, and the attention mechanism takes place before the executive control mechanism.
