连续报告任务中无效后线索对后线索效益的影响

The Influence of the Invalidretro-cue on the Retro-cue Benefit in Continuous Reporting Tasks

本文采用连续报告任务,从非线索指示项目的角度入手,探讨无效后线索的存在是否会影响后线索效应的产生,以此进一步了解"后线索效益"的产生机制。结果表明,无论采用空间后注意线索,还是非空间的颜色后注意线索,都产生了"后线索效益",即后线索确实提高了被试视觉工作记忆的表现。无效后线索的存在不会影响"后线索效益"的产生,该效益的理论解释符合优先提取说,即被试会利用后注意线索优先提取线索指示项目,产生更快和更准确的反应。

In this paper,from the perspective of non-cue indicating project,the continuous reporting task is adopted to explore whether the existence of invalid cues will affect the generation of post-cue effect,so as to further understand the mechanism of "post-cue effect".The results showed that both spatial and non-spatial color cues produced post-cue benefit,that is,post-cue did improve the performance of visual working memory.The existence of invalid post-cue does not affect the generation of "post-cue benefit",that is,the subjects will use the post-cue to extract the cue to indicate the project first and produce a faster and more accurate response.Therefore,the theoretical explanation of retro-cue benefit conforms to the priority extraction theory.
