EXERCISE 1.8 [extra - not in book]

What is the difference between recognition and recall in relation to human memory? Discuss the implications of this for interface designers.

answer available for tutors only

Recognition is the knowledge that you have seen something presented to you. Recall is the reproduction of something from memory. Recognition is simpler - the information required is provided as the cue. Recall is more complex as the information has to be retrieved from memory but cues can help this - e.g. using categories or images. Implications for interface designers include the need, where possible, to allow recognition by providing information up front (e.g. labelled buttons). Where this is not possible support recall by using cues such as iconic images, categories of menu item.
