Three experiments were conducted to examine the backward inhibition effect in attention switching within verbal working memory. Experiment one showed significant backward inhibition effect in a "tri-count task". Experiment two suggested that the effect was not due to a perceptual inhibition on the previously presented figure. Experiment three excluded the sequential expectancy explanation for this inhibition effect. Our results suggest that attention switching between working memory items is accompanied by inhibition of the previously attended working memory item. The findings are discussed in respect to the account of the executive function.
进行了三项实验来检验言语工作记忆中注意力转换的逆向抑制效应。实验一在“三计数任务”中显示出显著的逆向抑制效应。实验二表明该效应并非由于对先前呈现图形的知觉抑制。实验三排除了对这种抑制效应的顺序预期解释。我们的结果表明，工作记忆项目之间的注意力转换伴随着对先前关注的工作记忆项目的抑制。结合执行功能的观点对这些发现进行了讨论。
