Memory!
Forgetting
Long Term Memory
Cue Dependant Forgetting (accessibility)
forgotten information still in LTM but cannot be obtained
Trace Decay (availability)
info is forgotten from LTM is completely lost
Short Term Memory
Displacement
Peterson & Peterson (1959) found interference task resulted in poor recall > info has been pushed out by interference task
If STM is full, incoming info pushes out the current info
Trace Decay
Peterson & Peterson (1959) found interference task resulted in poor recall > info decays if not rehearsed
Results could support the idea of displacement because the ineterference task has required the STM to focus on that.
Likely that:
1. Displacement occurs only when STM is overloaded
2. STM forgetting is due to decay as attention is being averted to other info
info that is not rehearsed fades from STM
