- 1MILLER 1956capacity in STM
- 2AIMinvestigate capacity of STM
- 3METHODin the study - miller used a digit span technique (p hearing a list of no. and immediately trying to recall them in the correct order)
- 4RESULTSconcluded that the span of short term memory is 7+/-2
also found that - IF PEOPLE CHUNK THINGS TOGETHER, THEY CAN REMEMEBER MORE (LEAVES MORE CAPACITY AVAILABLE) - 5conclusioncapacity of STM is 7+/-2
- 6capacity duration codingcapacity - 7+/-2
duration - 18-30secs
Coding - Acoustic (processed through sound) - 7DURATION FOR STMpeterson&peterson
- 8AIMinvestigate duration of STM
- 9METHODp 924 undergraduates) presented with a consonant trigram
REHERSAL PREVENTED BY ASKING THEM TO COUNT BACKWARDS IN 3S FROM A SPECIFIED NO.
after intervals 3,6,9,12,15 or 18secs to over 30secs - 10Results3 sec - 80% recall
18 sec - 10% r
30 sec- 0% - 11Conclusionduration is 30sec or less if maintenance rehearsal is blocked (evidence for msm)
information fades from MSM (because of trace decay) - 12dis of p&p (low ecological val)P- low ecological val
E- p presented with a trigram (recalling it is an artificial and simple task- doesn't test true complexity of memory)
E- P&P results can't be generalised to real life (may not provide externally valid support for the claim that the duration of STM is limited to approx. 18-30 sec)
