Specifically, I talked about the prefrontal cortex and the short-term memory The Magical Number Four. Baddeley and Cowan found that the average human adult can only keep 4 items in short-term memory. And it’s even worse – this only works for simple or familiar things. You cannot keep four complex ideas in short-term memory (unless you’re already familiar with them); neither can you

It is thus also no surprise that the capacity of working memory (short-term memory) is highly correlated to IQ (Cohen & Sandberg 1977). The more you can trick your basic working memory capacity i.e., the more you can extend it over four or seven items, the higher your IQ will be. If it is no problem for you to read a nine-digit phone number and type it in confidently with no mistakes, you will

17/09/2008 · Visual short term memory (VSTM) is a memory system that stores visual information for a few seconds so that it can be used in the service of ongoing cognitive tasks. Compared with iconic memory representations, VSTM representations are longer lasting, more abstract, and more durable.

In contrast to the predictions from classical slot models of working memory capacity limited to a fixed number of items, i.e., Miller’s magical number 7 or Cowan’s magical number 4, we found that the number of visited locations to find the goals was consistently about 1.6 times the number of goals, whereas the number of correct choices before erring and the number of errorless trials

The distinction made by Cowan is an alternative way of grouping memory tasks: short-term memory would refer to the passive storage of information when rehearsal is prevented with storage capacity around four items. When rehearsal is allowed and controlled attention is involved, it is a working memory task and the capacity is closer to seven items.

As Cowan (2001) noted, many theorists with mathematical models of particular aspects of problem solving and thought have allowed the number of items in working memory to vary as a free parameter, and the models seem to settle on a value of about four, where the best fit is typically achieved.

Yet a new article in the Proceedings of the National Academy suggests that even 4 may be an overestimation.
Cowan reports results indicating that short-term memory capacity is 4 for whole report procedures and links this to sensory memory (Cowan, 2001). Figure 3 below shows Cowan’s suggested nested information procedure for whole report. In this any and all information is elevated from the activated long-term memory store into the focus of attention until this latter is full (Cowan, 2001). This
Cowan assumes that chunk-based capacity limits are synonymous with the essence of a “specialized STM mechanism.” In a single experiment, we measured the capacity, or span, of long-term memory and found that it, too, corresponds roughly to the magical number 4.
Cowan (2001) , however, reviewed the literature on this topic and concluded that the capacity limit for short-term memory is four items, plus or minus one (e.g., letters, words, sentences) and this finding is now known as the “magic 4” (see also Gobet & Clarkson, 2010 ). Several of Woodward’s “sources,” however, reported to him a number of words way above those findings. For example
Short-term memory allows individuals to recall stimuli, such as numbers or words, for several seconds to several minutes without rehearsal. Although the capacity of short-term memory is considered to be 7 ± 2 items, this can be increased through a process called chunking.

Abstract. A key motivation for understanding capacity in working memory (WM) is its relationship with fluid intelligence. Recent evidence has suggested a two-factor model that distinguishes between the number of representations that can be maintained in WM and the resolution of those representations.
Short‐term and/or working memory is needed to hold in mind the information that would produce a more mature, complete perspective in the preceding examples. This chapter considers some precise definitions of the terms and concepts that have bandied about, and gets into issues regarding some key processes of the mind, and how they change throughout childhood. Understanding childhood
in long-term memory, which allows more efficient storage in working memory, presumably by reducing the number of active elements that must be maintained in working memory.
“The Magical Number Seven, Plus or Minus Two: and therefore it is difficult to pin down the capacity of short-term or working memory to a number of chunks. Nonetheless, Cowan has proposed that working memory has a capacity of about four chunks in young adults (and less in children and older adults).

The term chunk refers to a unit of information in short-term memory—a string of letters, a word, or a series of numbers. The technique of chunking seeks to accommodate short-term memory limits by formatting information into a small number of units. The maximum number of chunks that can be efficiently processed by short-term memory is four, plus or minus one. For example, most people …
