Outline and Evaluate Two Explanations of Forgetting.

Extracts from this document...

Introduction

OUTLINE AND EVALUATE TWO EXPLANATIONS OF FORGETTING It can be said that while we were studying the capacity of long term memory and short term memory we over looked forgetting. The reason for memory missing has been tried to solve by many psychologists with different experiments. I can also say that from the studies it shows that memories are not lost due to capacity of the stores, but because it has been forgotten. There are three different types of forgetting in the short term memory which are trace decay, interference and diversion of attention. I will be talking about trace decay and showing experiments to support the theory. ...read more.

Middle

Information in short term memory certainly does disappear but it may not be because of spontaneous decay but it may be the result of interference. Another possible explanation for the Peterson and Peterson findings is that the interference task caused retroactive interference. This occurs when a second set of information pushes out earlier material from the memory store. It is most likely to happen when the two sets of information are sufficiently similar. Evidence supporting that point of view was reported by Reitman. The participants carried out either a syllable detection task or a tone detection task during the retention interval. Those who performed the syllable detection task had much lower recall than those who performed the tone detection task, presumably because syllables interfered much more than tones. ...read more.

Conclusion

Endel Tulving conducted a number of studies on cue dependent forgetting. In one study Tulving and Psotka compared the cue dependent explanation of forgetting with the interference theory of forgetting. In this experiment participants were given word lists. There were six different word lists, each with 24 words. Each set of words was divided was divided into six different categories. Cue dependent forgetting is a classic example of forgetting because of lack of accessibility. The information is in memory, but just cannot be accessed until an appropriate cue is given and suddenly it is found. Such information is said to be available but not accessible. Cue dependent forgetting probably offers more insights and has more real- world validity than interference theory, but it does depend on whether the memory failure is due to availability or accessibility. ...read more.

Another reason for choosing this experimental method is its reliability as it can easily be replicated. An independent measures design was used. This meant testing two groups, one for recall in the same environment where

    However, the sample was not too small to be unrepresentative and 30 was a manageable amount of participants. Different genders in this experiment are considered as a confounding variable since different genders have their individual differences. However, gender differences were not considered as a major variable that would significantly affect

    So you can hold 5-9 items in your STM. The serial probe technique could support this theory because it was found out that the participants remembered what came after the later numbers rather than the earlier numbers. This could be because the numbers came later in the sequence they had displaced the earlier numbers in the sequence.

    Group two had the greatest improvement. The mean number of the 20 questions correct for this group improved from 0.9 to 10.7. This supports the idea that smells act as a cue to aid memory. A study that refutes Tulving's cue-dependent theory is Underwood (1957); he did a study on

    a recall average of 45% this was the highest of the results and that the group with similar meaning to the first words had the poorest results with the average recall being 12%. The conclusion to this experiment was that retroactive interference had taken place; this is because the learning

  1. Retrieval Induced Forgetting in Coherent Narrative Text.

    Unlike the first experiment, there was a condition in which no retrieval practiced information was presented. Participants were to give facts about general geographical knowledge like the capitals of actual states. The recall of Rp+ items was significantly greater than the recall of Nrp items.

  2. To What Extent Is motivated Forgetting Produced By Failure Feedback?

    So when they are tested again, on the same information, they will remember less because they have repressed it. This has the advantage that it is experimentally generated so we know that the recall of the information is actually true.
