不同引导任务对图-字Stroop效应的影响——对注意力敏感模型的验证

The influence of induction tasks on the figure-word Stroop effect——Verification of the Attention Sensitization Model

将引导任务与图-字Stroop任务相结合,通过考察不同引导任务对Stroop效应的影响来探讨注意是否影响自动化加工,以及如何影响的问题,以进一步验证注意力敏感模型.两个实验的结果发现:引导任务与Stroop任务中的条件匹配之间存在显著的交互作用;不同引导任务对Stroop效应量的影响不同,语义引导任务下的Stroop效应量明显高于知觉引导任务;引导任务下的反应时间显著高于无引导任务,正确率恰好相反.结论:实验结果与注意力敏感模型相符.注意系统对自动化加工具有调节作用.这种调节作用是通过增加对相关通路的敏感性,减低无关通路的敏感性来实现的.

In current study the induction task paradigm combined with the figure-word Stroop task paradigm was implemented.We attempted to verify whether the regulation mechanism of attention to automatic processes conforms the Attention Sensitization Model by observing the influence of semantic and perceptual induction tasks in the previous induction tasks on semantic and perceptual processes in the subsequent Stroop tasks.The results indicate:The interaction of induction tasks and conditional matching in Stroop tasks was significant.Different induction tasks have different effects on the Stroop effect-size,and the Stroop effect-size under the condition of semantic induction was significantly larger than that in perceptual.The reaction time for induction tasks was markedly larger than that for non-induction task,but the accuracy was opposite.Conclusion:The results of present study supported the view of the Attention Sensitization Model.Attention system can modulate the automatic processes by means of changing the sensitivity of related and unrelated pathways.
