使用時間例子
林煜軒團隊先找了將近100位大學生,由精神科醫師詢問使用手機的狀況,同時安裝Know Addiction記錄一個月的使用情況。結果發現,大學生自己認為的使用時間是平均每週20小時,然而手機的記錄卻是每週30小時,也就是說,自己感覺的使用時間有低估的現象,實際使用時間是其1.5倍。

Although switch costs may be relatively small, sometimes just a few tenths of a second per switch, they can add up to large amounts when people switch repeatedly back and forth between tasks. Thus, multitasking may seem efficient on the surface but may actually take more time in the end and involve more error. Meyer has said that even brief mental blocks created by shifting between tasks can cost as much as 40 percent of someone's productive time.
