- DECAY THEORY
- Memories have a physcial basis known as a trace. This trace will decay in time if not passed to the long term memory.
- PETERSON &PETERSON found that memories were held in the short term memory for around 18 seconds and decay via trace decay
- participants recalled fewe utens the longer the delay before recall
- WAUGH &NORMAN given a number and had to state the number that follows it. time gap before recall meant they forgot
- better recall when said faster
- better recal when probe numbe closer to end
- JENKINS & DALLENBACH participant learned nonsence syllables, some slept some carried on, those who remained awake forgot more than those who slept
- indicates it is interference that effects recall ability rather than decay
- difficult to test objectively, possible that factors such as interference or lack of cues may effect recall ability
- lab setting tests effect ecological validity.
