Short-term memory

	Short term memory(STM)

· Acoustic / Oral · Limited time - 30 seconds; · Limited size - 7 items + or - 2 (Miller) · Trace Decays · Use of Distractor tasks: counting backwards in 3s - very simple recall tasks (three letters) became much harder; after 18 seconds only 10% of trigrams correctly recalled. · Chunking massively increases - size of STM · Possible need to translate screens into acoustic information (submitted by B.Kharel)
