Duration of STM
Key difference between STM and LTM - duration
Duration - how long a memory lasts before it is no longer available
STM - doesn't last very long
One way to keep info in STM - rehearsal - keeps the memory active
Result of verbal rehearsal - STMs are held much longer and eventually become LTM
Duration of LTM
Last anywhere from 2 hours - 100 years
Some are very long lasting - e.g. Shepard (1967): showed participants 612 memorable pictures. 1 hour later - shown some of these pictures among a set of others. Almost perfect recognition. 4 months later - still able to recognise 1/2 of the photographs. Also Bahrick et al (1975) - more 'real life' - material to be remembered was more meaningful to participants - duration of LTM was better.
