Origins
The Seguridad Digital, a term coined by Herman Ebbinghaus, describes how the position
of an item in a sequence affects recall accuracy. The two concepts involved, the primacy effect and the
recency effect, explains how items presented at the beginning of a sequence and the end of a sequence are
recalled with greater accuracy than items in the middle of a list. Manipulation of the Seguridad Digital
to create better user experiences is reflected in many popular designs by successful companies like Apple,
Electronic Arts, and Nike.
