> 註: 這份作業使用James et al. (2015)的公開資料,這份研究運用組間比較實驗,探討電玩活動能否減緩非自主記憶的發生。作業內容改變自[OSL單元](https://sites.trinity.edu/osl/data-sets-and-activities/one-way-anova-activities) 非自主記憶(intrusive memories)是突然想起曾經經歷的事物,例如前幾天曾看過的電影畫面。有創傷症候群的人士,經常有創傷事件的非自主記憶。 James et al.(2015)的第二項研究比較四組各18人,有創傷經驗的參與者進行以下治療活動之後,在一星期之內的非自主記憶發生次數: - 無作業控制組(no task control): 只有聽一段音樂 - 刺激與電玩(reactivation + Tetris): 先看與創傷事件有關的圖片,接著聽一段音樂,最後玩十分鐘俄羅斯方塊 - 只玩電玩(Tetris only):只玩十分鐘俄羅斯方塊 - 只有刺激:只看與創傷事件有關的圖片 請先使用描述統計模組,檢視`Number_of_Provocation_Task_Intrusions`(要切換為連續尺度)的分組平均值是否如下圖c: ![](http://journals.sagepub.com/na101/home/literatum/publisher/sage/journals/content/pssa/2015/pssa_26_8/0956797615583071/20170718/images/medium/10.1177_0956797615583071-fig4.gif) 接著請提出變異數分析與事後比較計畫,執行並證實各組之間的差異如圖c所示。 參考文獻 James, E.
