Lasts ¼ to 3 seconds A tt e nt io n 2 nd STM (working memory): new info is transferred from sensory memory; old info is retrieved from long term memory; limited capacity for info; lasts ~20 seconds Encoding LTM (long term memory): info that has been encoded in short- term memory is stored; unlimited capacity for info; can be potentially permanent. Retrieval How do we increase or extend STM? If the info is rehearsed (repeated) , it will maintain in STM longer. Maintenance rehearsal : the mental or verbal repetition of info in order to maintain it beyond the usual 20 sec duration of STM Chunking : increasing the amount of info that can be held in STM y grouping related items together into a single unit, or chunk Working Memory : STM system involved in the temporary storage & active manipulation of info; includes the phonological loop (verbal material like numbers or words), visuospatial sketchpad (spatial or visual material),
