人们倾向于记住一系列项目中的开头项目和末尾项目[3]。
应该如何排列列表中的项目?
将重要的项目放在列表的开头和结尾处,使用户做决策时,能最大程度地回想起这些项目。列表开头的项目比后面的更容易记住,而列表末尾的项目在展示后更容易回想起来。
具体而言,做法如下:
回想列表中的项目时,列表两端的项目比中间位置的项目更容易回想起来。
人们易于回想起列表开头的项目的现象称为首因效应,而人们易于回想起列表末尾的项目的现象称为近因效应。
向用户显示长的信息列表,会严重限制人们有限的资源和有限的记忆系统——特别是短期内存,一次只能记住三到四个项目信息或信息块。 人们回想以前看过的的项目也受到初始处理和后续回忆之间的事件的严重影响。[6]

[3]原文:We have a tendency to recall the first and the last items in a series best
[4]原文:Add cues to things previously encountered in order to inititate recognition of the action and recall its meaning. Cues are most often graphical, but can also include sounds.
[5]原文:Limit the amount of recall required to retain relevant information to complete a task or simply to retrieve information. Human attention is limited and we are only capable of maintaining up to around five items in our short-term memory.
[6]原文:Presenting long lists of information to users, significantly strains our limited resources and restricted memory systems – especially short-term memory, where only three or four items or chunks of information can be maintained at one time. Our ability to recall previously presented items is also severely impacted by events between initial processing and later recall.
