| 摘 要： | 注意捕获研究对于探讨两种控制过程:自上而下的加工与自下而上的加工之间的关系具有重要的意义。本文通过检验不同工作记忆负荷对注意捕获的影响,探讨自上而下的认知控制对注意捕获的影响机制。本研究共包括二个实验:实验一比较了单、双任务条件对颜色干扰子注意捕获的影响;实验二探讨了不同工作记忆负荷对颜色干扰子注意捕获的影响。实验结果表明:工作记忆不仅在选择性注意任务中具有认知控制作用,而且这种作用能扩展到注意捕获现象中。注意捕获不是纯粹的刺激驱动的加工过程,它还受到自上而下的认知控制的调节。具体表现为,随着工作记忆负荷水平的增加,无关干扰子产生的注意捕获的程度增大。

| Abstract: | Attentional capture is of great importance in revealing the relationship between two kinds of attentional control:bottom-up process and top-down process.The study explored the effect of working memory load on attentional capture,in order to probe into the effect of top-down cognitive control on attentional capture.Two experiments' programs were run on a Dell computer using DMDX.In Experiment 1,we compared capture by a color singleton during visual search between a single-task condition and a dualtask condit... |
