Aims: To contrast the coding of short term and long term memory.

Procedure: Participants were given four sets of words to recall;

Participants were asked to recall the words either immediately or after an interval of time.

Results: When participants were asked to recall the words immediately, therefore using short term memory, they did less well with acoustically similar words than those which sounded different.

When participants were using long term memory, i.e. after an interval,

they performed the same on lists A & B but there were pronounced differences between the words that had the same or different meanings.

Conclusion: This experiment indicates that short term memory codes are mainly acoustic whilst long term memory codes are mainly semantic.

Bahrick et al 1975 Duration in LTM (&face recognition)

Aims: Bahrick et al aimed to investigate the duration of very long term memory (VLTM). They wanted to demonstrate that memories could endure in order to support the assumption that the duration o
