In research that attempts to measure the capacity of visual memory. Nowhere is this connection more obvious than Systems or memory processes without also determining the nature of Thesis of this review will be that one cannot fully understand memory Research on visual memory has shifted toward a representation-basedĮmphasis, focusing on the contents of memory and attempting toĭetermine the format and structure of remembered information. Informative about the nature of stored memory representations. Systems and characterizing their function but has been less ThisĪpproach has been valuable for establishing a taxonomy of memory Systems and exploring different stages of memory processing. Traditional memory research has focused on identifying separate memory Most others have already pointed to some great papers on this and the fact that the literature has moved on from these claims now (as usual, 'bold' claims so often end up being false), but there's a great and very recent review on visual memory by Brady etal (2011) that gives a great deal of detail and is available via open access online here :
#Magic number 7 plus
"The magical number seven, plus or minus two: Some limits on our capacity for processing information". Oxford, U.K.: Oxford University Press.Īnd here is Millers original article, it's actually fun to read: Della Sala (Ed.), Tall tales about the mind & brain: Separating fact from fiction (pp. Here is an short article that answers your question in more detail:Ĭowan, N., Morey, C.C., & Chen, Z. So I guess the short answer is: No it is not valid, and it has never really been. However, the comparison was not very serious and mostly rhetorical.

So he tried to connect unrelated lines of research, with the only connection between them being that they show cognitive limitations of similar magnitude ("7+/-2 items"). Jeanne Farrington EdD, "Seven plus or minus two"Īs far as I recall, the "magic" of the number seven is that George Miller had to give a 1h-presentation while not having enough research on one particular topic to talk about this long. One could argue that my working memory is worse than average, but I would never agree to such a statement.īut the question remains and is puzzling my mind. When I go shopping, I need to write a shopping list if there are more than four things I need to buy and by this not forget what it was I'm supposed to buy.

In my daily life, I can see that this is more likely. However recent research question Miller's Law stating that the correct number a human being can hold in working memory is three or four. I've learned this in school as well, and I often use the magic number seven when it comes to grouping of elements in more logical units. This is frequently referred to as Miller's Law. It supposedly argues that the number of objects an average human can hold in working memory is 7 ± 2. Miller published "The Magical Number Seven, Plus or Minus Two: Some Limits on Our Capacity for Processing Information" in 1956 and is one of the most highly cited papers in psychology.
