Forgetting

Short Term Memory

Trace Decay

info that is not rehearsed fades from STM

Peterson & Peterson (1959) found interference task resulted in poor recall > info decays if not rehearsed

r

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 overloaded2. STM forgetting is due to decay as attention is being averted to other info

Displacement

If STM is full, incoming info pushes out the current info

Peterson & Peterson (1959) found interference task resulted in poor recall > info has been pushed out by interference task

Long Term Memory

Trace Decay (availability)

info is forgotten from LTM is completely lost

Cue Dependant Forgetting (accessibility)

forgotten information still in LTM but cannot be obtained
