Memory {short-term memory}| (STM) {active memory} {primary memory} {working memory} {activity-dependent memory} can rehearse immediate memories, hold memories in consciousness, assist long-term memory, and decay in minutes to hours. Short-term memory puts objects and events in sequence to coordinate acquisition and retrieval.
properties: chunks
Short-term memory holds data chunks. Short-term memory holds 30 bits. People can remember chunks of three, if they must remember sequence. People can remember chunks of six or seven if there is no order [Cowan, 2001] [Miller, 1956] [Riddoch and Humphreys, 1995] [Shallice, 1988] [Sternberg, 1966] [Vallar and Shallice, 1990].
properties: interference
STM can have semantic interference.
biology: cells
Short-term memory involves no cell changes or protein synthesis.
biology: drugs
Amphetamine and strychnine affect short-term memory.
biology: brain
Prefrontal cortex neurons hold short-term memories for objects, locations, or both [Baddeley, 1986] [Baddeley, 1990] [Baddeley, 2000].
factors: age
Old age or brain damage does not affect short-term memory.
factors: language
Language production and comprehension require short-term memory.
working memory
Phonological loop stores sounds with meaning, such as spoken words. Visuospatial sketchpad stores images, such as faces and scenes. Working memory encodes attended content from sensory memory for non-conscious storage into long-term memory or other processing, such as sentence comprehension, and integrates content activated from long-term memory. Working memory holds content being actively processed, including conscious and near-conscious experiences and recently attended content, and includes perceptual and semantic representations. Working memory includes a goal-driven controller to determine which process to perform. Attention is part of working memory, or working memory holds attended conscious content {focus, Baddeley} [Baddeley, 1986] [Baddeley, 1990] [Baddeley, 2000].
