[2][3][4] It was written by the cognitive psychologist George A. Miller of Harvard University 's Department of Psychology and published in ...
Short-term memory. Short-term memory (or " primary " or " active memory ") is the capacity for holding a small amount of information in an active, readily available state for a short interval.
