Sensory Memory
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
Sensory memory holds a brief, high-capacity trace of incoming sensory information for a fraction of a second.
Show
A sparkler moved quickly in a dark room appears to draw a continuous line of light.
Watch for
Sensory memory is not attended to. Nearly all of it decays before anything is selected from it.
