视觉与言语工作记忆表征对视觉注意的引导

通过三个实验,探讨不同时间进程下视觉和言语工作记忆表征对视觉注意的引导。实验1采用注意引导与注意探测任务同时呈现的范式,探讨不同记忆项与注意项时间间隔(SOA)条件下言语工作记忆表征对视觉注意的引导。结果发现,当SOA较短时言语工作记忆表征对视觉注意有引导效应,而SOA较长时未观察到引导效应;实验2、3采用注意引导任务与注意探测任务分离范式,分别探讨在不同SOA条件下言语和视觉工作记忆表征对视觉注意的引导。结果发现,不同SOA条件下言语和视觉工作记忆表征均能引导视觉注意。研究表明,不同实验范式对言语工作记忆表征对视觉注意的引导有明显影响,视觉比言语工作记忆表征能在更广泛条件下引导视觉注意。

The Attentional Guidance Effect of Visual and Verbal Working Memory Representation

Three experiments were conducted to explore the different attentional guidance effects from visual and verbal working memory (WM) representation in different stimulus-onset asynchrony (SOA) conditions. In Experiment 1, we explored how the effect of verbal WM on visual attention were influenced by SOA when the visual guidance task and visual detection task were presented simultaneously. The results showed when the SOA was 300ms and 1000ms, the attentional guidance effect of verbal WM was observed, while when the SOA was 3500ms, the attentional guidance effect wasn't observed. In Experiment 2 and 3, we explored how the effects of verbal WM and visual WM on visual attention were influenced by SOA when the visual guidance task and visual detection task were presented seguentially. The results showed the attentional guidance effect was observed in all WM representation and SOA conditions. These results indicate that the effect of verbal WM representation on attentional guidance is influenced by task paradigm. Attentional guidance effect can be observed from visual WM representation under more widely conditions than verbal WM representation.
