From The Chronicle’s Wired Campus blog: “Students Retain Information in Print-Like Formats Better”:
The report, "To Scroll or Not to Scroll: Scrolling, Working Memory Capacity, and Comprehending Complex Texts," described how two groups, of 20 students each, wrote essays after reading materials in either in print-like or scrolling formats. Those given the scrolling versions to read had poorer comprehension of the material.
If memory itself is the problem, then there is this: “Can't get rid of your memories? Call Death Bear” (LA Times).
