The Magical Number Seven, Plus or Minus Two: Some Limits on our Capacity for Processing Information[1] George A. Miller (1956) Harvard University First published in Psychological Review, 63, 81-97. reproduced with permission, by Stephen Malinowski: http://www.yorku.ca/dept/psych/classics/Miller/ The classic paper on chunking. I recommend it. I find particularly interesting Miller's identification of how concurrent use of other modalities can help. ---- Diane Wilson paraphrases that concept as "People can remember seven plus or minus two items at a time" in: http://www.lava.net/~dewilson/web/assumptions.html This assumption is sometimes misunderstood. The key word here is remember. It applies to recall, not recognition. People should have to recall only a limited amount of information. They can recognize a correct response from a much larger set of choices. ---- The need to remember, short-term, is certainly what we are addressing for accessibility. Recognition, however tedious, can happen if targets are adequately differentiated in their descriptions, even if in a longer list. Regards/Harvey Bingham
