In the study of vision, visual short-term memory (VSTM) is one of three broad memory systems including iconic memory and long-term memory. VSTM is a type of short-term memory, but one limited to information within the visual domain.
The term VSTM refers in a theory-neutral manner to the non-permanent storage of visual information over an extended period of time. The Visuospatial Sketchpad is a VSTM subcomponent within the theoretical model of working memory proposed by Alan Baddeley. Whereas iconic memories are fragile, decay rapidly, and are unable to be actively maintained, visual short-term memories are robust to subsequent stimuli and last over many seconds. VSTM is distinguished from long-term memory, on the other hand, primarily by its very limited capacity.

Famous quotes containing the words visual, short-term and/or memory:
“To write well, to have style ... is to paint. The master faculty of style is therefore the visual memory. If a writer does not see what he describes—countrysides and figures, movements and gestures—how could he have a style, that is originality?”
—Rémy De Gourmont (1858–1915)
“I still believe that if your aim is to change the world, journalism is a more immediate short-term weapon.”
—Tom Stoppard (b. 1937)
“‘I’m sorry that I spelt the word:
I hate to go above you,
Because’Mthe brown eyes lower fell—
‘Because, you see, I love you!’
Still memory to a grey-haired man
That sweet child-face is showing.
Dear girl! the grasses on her grave
Have forty years been growing.”
—John Greenleaf Whittier (1807–1892)
