Displacement - theory of forgetting

?
Definition
Rehearsed information is written over
1 of 12
STM
Rehearsal loop in STM has limited capacity
2 of 12
The serial position effect
First and last thing learned is well remembered, middle information is displaced in the rehearsal loop and forgotten
3 of 12
Primacy effect
First information learnt is well remembered as it is still in the rehearsal loop to LTM
4 of 12
Recency effect
Information learnt last is remembered well as it is still in the rehearsal loop and available from immediate recall
5 of 12
Middle information
Not remembered well as it has been displaced by the most recent bit of information and so doesn't go through the rehearsal loop to LTM
6 of 12
Glanzer and Cuntiz
Delaying recall by 30 seconds with an interference task prevents recency effect as the most recent bit of information is displaced by the task
7 of 12
Supporting evidence
WMM and MSM both talk about a loop in STM which through rehearsal moves information into LTM
8 of 12
Supporting evidence
Loop has limited capacity - explains why displacement might happen
9 of 12
Supporting evidence
Experiments are reliable and scientific
10 of 12
Conflicting evidence
Could be interference not displacement
11 of 12
Conflicting evidence
Artificial tasks - not valid
