Describing Trace Decay Theory of Forgetting Sample Essay

Trace decay theory can be applied to explicate forgetting from both STM and LTM. * It is based on the thought that information creates a neurological hint in the encephalon. known as an memory trace. when it is encoded. This means a alteration has occurred in the construction of the encephalon. * Hebb ( 1949 ) proposed that whilst acquisition is first taking topographic point. the memory trace is really delicate and apt to break. It grows stronger and less likely to be destroyed the more learning ( dry run ) takes topographic point. * Without dry run or pattern. this engram slices over clip because it is non being strengthened. Forgeting hence occurs because the information is non physically available for retrieval. * Forgeting occurs from STM due to the shops limited continuance if dry run does non take topographic point ( it will melt after 30 seconds ) . How do we measure theories /explanations?

* “Evaluate” = what are the strengths ( v ) and restrictions ( X ) of the theory/explanation? What do I include in the strengths and restrictions?

13a ) – The hint decay theory. revolves around the thought that a memory creates a neurological hint known as an memory trace in our encephalon. and it can be applied to explicate forgetting from both STM and LTM. The less you rehearse the more opportunity of burying it and this neurological hint decaying. The memory trace besides fades over clip if it is non rehearsed. as it is non being strengthened. Forgeting hence occurs because the information is non physically available for retrieval as the memory trace has faded off due to miss of dry run over clip. 13b ) – Trace decay can non explicate why some long-run memory engram’s. such as flashbulb memories. look to be immune to disintegrate. Another appraising point is that it is supported by research conducted by Penfield who found that different memories could be appear in epileptic patients by examining different countries of the encephalon screening that memories do hold a physical construction.

ONE OTHER THEORY OF FORGETTING: TRACE DECAY

AO1 Description

* Trace decay theory can be applied to explicate forgetting from both STM and LTM.

* It is based on the thought that information creates a neurological hint in the encephalon. known as an memory trace. when it is encoded. This means a alteration has occurred in the construction of the encephalon.

* Hebb ( 1949 ) proposed that whilst acquisition is first taking topographic point. the memory trace is really delicate and apt to break. It grows stronger and less likely to be destroyed the more learning ( dry run ) takes topographic point.

* Without dry run or pattern. this engram slices over clip because it is non being strengthened. Forgeting hence occurs because the information is non physically available for retrieval.

* Forgeting occurs from STM due to the shops limited continuance if dry run does non take topographic point ( it will melt after 30 seconds ) .

AO2 Evaluation

* This theory is supported by research conducted by Penfield who found that different memories could be evoked in epileptic patients by examining different countries of the encephalon screening that memories do hold a physical construction. However. this does non turn out that the memory trace will disintegrate over clip.

* Research by Jenkins & A ; Dallenbach ( 1924 ) refutes the hint decay theory: They found that participants who remained awake between larning and remember forgot more than those who slept. This suggests that intervention instead than trace-decay causes burying.

* Then once more. this theory is relevant to understanding our mundane experiences of burying as it is consistent with the forgetting demonstrated by people with Alzheimer’s disease who seem to lose memories ( a physical procedure ) instead than be unable to recover them.

* Nevertheless. hint decay can non explicate why some long-run memory engram’s. such as flashbulb memories. look to be immune to disintegrate.

* Trace decay besides has trouble explicating why stuff which can non be remembered at one clip can be remembered at a future clip: If the hint has decayed it should ne’er be available.

1. The first cue is from a odor which reminded him of his old occupation. This cue worked like a context dependant cue. Memory retrieval can be r triggered by reproduction of the context in which the memory was encoded ; in this instance it was a odor. which is a context dependant cue. 2. I have walked into my primary school before and noticed the wall we all used to play about. we merely seemed to congregate around this wall. It reminded me of running around it and playing tig when I was small. this is a context cue. which is context dependant. and in this instance the cue was the scene and location.
