Memory span refers to the longest list of items ( e . g ., digits, letters, words ) that a person can repeat back in correct order on 50 % of trials immediately after presentation.

On " the Hill, " where the sweep of historical memory spans the two centuries since it was built up by developers who also sliced off its top, the influx of mega-rich appears to evoke mixed feelings.

He noticed that memory span is approximately the same for stimuli with vastly different amount of information for instance, binary digits have 1 bit each; decimal digits have 3.32 bits each; words have about 10 bits each.

:: : Here is some research with the snappy title " Effects of Age on Measures of Complex Working Memory Span in the Beagle Dog ( Canis familiaris ) Using Two Versions of a Spatial List Learning Paradigm ".

In a study done by Drewnowski and Murdock, a visual list of English words was found to have an immediate recall of 4.82 words while an auditory representation of this same list led to a memory span of 5.36, a statistically significant variance.

By contrast, younger adults improved only when PI reductions were combined, suggesting that they are relatively resistant to PI . The fact that PI contributes to span performance raises a number of interesting possibilities with respect to previously held assumptions based on memory span performance.

Miller recognized that the correspondence between the limits of one-dimensional absolute judgment and of short-term memory span was only a coincidence, because only the first limit, not the second, can be characterized in information-theoretic terms ( i . e ., as a roughly constant number of bits ).

In an early and highly influential article, The Magical Number Seven, Plus or Minus Two, the psychologist George Miller suggested that human short-term memory has a forward memory span of approximately seven items plus or minus two and that that was well known at the time ( it seems to go back to the 19th-century researcher Wundt ).

Experiments dealing with memory span have been conducted by George Miller in 1956 that indicated, " Most common number of items that can be stored in the working memory is five plus or minus two . However, if this information is not retained and stored ( consolidated ) in one's long-term memory, it will fade quickly.
