采用元分析的方法探討工作記憶容量與走神頻率之間的關系,以及影響二者關系的調節因素。通過文獻檢索,共獲得17項研究和73個獨立效應量,包含了10834名被試。元分析結果發現:(1)整體上工作記憶容量與走神頻率之間呈負相關。(2)使用不同的測量工具所測的工作記憶容量與走神頻率的相關有顯著差異,同時使用操作廣度、閱讀廣度和對稱廣度進行測量時,工作記憶容量與走神頻率之間的相關最高。(3)走神頻率的測量方式對工作記憶容量與走神頻率的關系有顯著影響,使用探針方式時二者相關最高。(4)任務難度對工作記憶容量與走神頻率關系的調節作用并不顯著。

A meta-analysis was conducted to explore the relationship between working memory capacity and mind wandering frequency and the factors affecting this relationship. Through literature retrieval, 17 cases and 73 independent effect sizes together with 10834 participants which met the inclusion criteria of meta-analysis were selected. Heterogeneity test indicated that random effects model was appropriate for the meta-analysis. The result of funnel plot and Egger’s intercept illustrated that there was no publication bias.The main-effect test findings demonstrated that working memory capacity was significantly associated with mind wandering frequency. The moderator analysis revealed that the measurement tools of working memory capacity and mind wandering frequency moderated the relationship between working memory capacity and mind wandering frequency but the task difficulty did not.
