It was assumed that memory can be disrupted or interfered with by what we have previously learned or by what we will learn in the future. This idea suggests that information in long term memory may become confused or combined with other information during encoding thus distorting or disrupting memories.

Atkinson, R. C., & Shiffrin, R. M. (1968). “Chapter: Human memory: A proposed system and its control processes”. In Spence, K. W., & Spence, J. T. The psychology of learning and motivation (Volume 2). New York: Academic Press. pp. 89–195. The first words in the list are rehearsed more frequently because at the time they are presented they do not have to compete with other words for the limited capacity of the short-term store. This means that words early in the list are more likely to be transferred to long-term memory.

The research into the processes involved in consolidation reminds us that memory relies on biological processes, although the exact manner by which neurons are altered during the formation of new memories has not yet been fully explained. Tulving and Pearlstone’s (1966) study involved external cues (e.g. presenting category names). However, cue-dependent forgetting has also been shown with internal cues (e.g. mood state). Information about current mood state is often stored in the memory trace, and there is more forgetting if the mood state at the time of retrieval is different. The notion that there should be less forgetting when the mood state at learning and at retrieval is the same is generally known as mood-state-dependent memory .

The maximum strain criterion has a similar form except that the principal strains are compared with experimentally determined uniaxial strains at failure, i.e.,First, the memory has disappeared – it is no longer available. Second, the memory is still stored in the memory system but, for some reason, it cannot be retrieved. The findings from studies using free recall are fairly reliable and they produce similar results on each occasion. If you take each item in the list and calculate the probability of participants recalling it (by averaging recall of the word over all participants) and plot this against the item’s position in the list, it results in the serial position curve (Figure 1). Context also refers to the way information is presented. For example, words may be printed, spoken or sung, they may be presented in meaningful groups – in categories such as lists of animals or furniture – or as a random collection without any link between them. Evidence indicates that retrieval is more likely when the context at encoding matches the context at retrieval.
