空间和非空间的“后线索效益”

Spatial and Non-spatial Retro-Cue Effect

本文采用连续报告范式,探讨空间以及非空间后注意线索对工作记忆的影响,以期进一步了解"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,都产生了类似的"后线索效益",即有后注意线索时被试的记忆行为要优于无后注意线索。但该效益主要表现在反应时而非正确率上,因此该结果验证了"后线索效益"的优先提取说,即"后线索效益"主要源于被试会利用后注意线索优先提取线索指示项目,导致更快的反应。

The continuous report task paradigm was used to explore the impact of spatial and non-spatial retro-cues on working memory,for the purpose of further understanding the mechanism of"retro-cue effect".The results showed that the memory performance of items in the condition of retrospective attention cues were significantly greater than no-cues.It means that the similar effects were found in both the spatial and non-spatial retrospective attention cues.However,the effect is mainly reflected in the average reaction time rather than the correct rate.Thus,the prioritization during retrieval is supported in this study.It suggested that"retro-cue effect"is mainly produced from the prior retrieval of items under retrospective attention cues which participants would use,and lead to a faster response.
