Short-term memory


A classical model of memory developed in the 1960s assumed that all memories pass from a short-term to a long-term store after a small period of time.


In 1974, Robert Bjork and William B.


Thus, while there are short-term memory components to working memory models, the concept of short-term memory is distinct from these more hypothetical concepts. Within Baddeley's influential 1986 model of working memory there are two short-term storage mechanisms: the phonological loop and the visuospatial sketchpad.


A commonly cited capacity of items to remember is The Magical Number Seven, Plus or Minus Two (also called Miller's Law, despite Miller calling the figure "little more than a joke" (Miller, 1989, page 401)).


Since the 1990s, however, there has been a surge in research on visual short-term memory, and also increasing work on spatial short-term memory. == Duration == The limited duration of short-term memory (~18 seconds without a form of memory rehearsal) quickly suggests that its contents spontaneously decay over time.
