Question

Explain the basic difference between these three theories: 1. Cue dependent forgetting: 2. Intereference theory: 3. Trace decay:

Answer 1

1. Cue dependent forgetting

This is a theory of why forgetting happens in LTM. As per this hypothesis proposed by Tulving, forgetting happens when the correct cue isn't accessible for recovering the memory. At the point when a memory is encoded it leaves a memory follow which additionally stores data about the way we felt or the place we were in at the season of encoding. All together for this memory to be gotten to again a recovery cue (provoke) is required. The encoding specificity standard expresses 'the more prominent the similitude between the encoding occasion and the recovery occasion, the more noteworthy the probability of reviewing the first memory'.

There are 2 sorts of cue that can help review – context and state. Context cues imply that on the off chance that we are not in an indistinguishable place from we were when taking in, the memory may not be available. This is the reason when you return to your old school you may review more recollections of being there. State cues imply that on the off chance that we are not in an indistinguishable physical and passionate state from we were the point at which the learning happened, we will most likely be unable to get to the memory. Cases of state cues incorporate – bliss, fear or notwithstanding being smashed!

2. Interferrnece theory

It was accepted that memory can be upset or meddled with by what we have beforehand learned or by what we will learn later on. This thought recommends that data in long haul memory may wind up noticeably mistook or joined for other data amid encoding along these lines twisting or upsetting recollections.

Interference theory expresses that overlooking happens in light of the fact that recollections meddle with and upset each other, as it were overlooking happens due to obstruction from different recollections (Baddeley, 1999). There are two routes in which impedance can cause overlooking:

1. Proactive interferring (pro=forward) happens when you can't take in another errand in view of an old assignment that had been learnt. At the point when what we definitely know meddles with what we are at present learning – where old recollections disturb new recollections.

2. Retroactive interferring (retro=backward) happens when you overlook a formerly learnt errand because of the learning of another assignment. As it were, later learning meddles with prior learning - where new recollections upset old recollections.

3. Trace decay theory

This clarification of forgetting in here and now memory accept that memories leave a trace in the mind. A trace is some type of physical and additionally substance change in the sensory system.

Trace decay hypothesis expresses that forgetting happens because of the programmed decay or blurring of the memory trace. Trace decay hypothesis concentrates on time and the constrained length of here and now memory.

This hypothesis recommends here and now memory can just hold data for in the vicinity of 15 and 30 seconds unless it is practiced. After this time the data/trace decays and blurs away.
