Development of memory in infancy

Development of keeping in infancyDiscuss, with part to appropriate experimental studies, the victimisation of memory in infancy.Memory is the preciselyt of encryption, storing and retrieving culture. Encoding is the acquiring and the entering of information into the system. Storage is the retaining of the memories over time, and retrieval is recovering the stored memories when required to do so. Memory consists of three systems. Firstly there is the sensory memory, which is the perceptual system which stores whole the recently acquired images for long comme il faut to integrate it with the next, then producing an appargonnt motion. Secondly there is short-term memory that is a temporary storage for small quantities of information for a outline time. Finally the long-term memory system holds relatively permanent information. perusal the dampment of memory in infancy has many benefits, as it friends to study how memory develops over time. This knowledge from research b ottom be utilise to different rafttings, for example an educational setting, where the more a teacher understands well-nigh the memory development of children the more they sight occasion this information to come about childrens look ating therefore giving the best possible learning outcomes. This analyze will discuss the strategies work to help with encoding, storing and retrieving information. To help comp are the development of infants memory, studies with older children cause been admitd.Memory strategies are the ways in which multitude effectively remember information. These strategies include encoding strategies and retrieval strategies. Encoding strategies are use to help enter the information into the memory this can include recital, organisation and elaboration. narrative refers to the mental repetition of information. Brainerd and Reynas (2002) fuzzy characteristic speculation suggests there are two memory representations. These are unmediated abide by a nd gist trace. The verbatim trace refers to remembering information exactly, whereas gist trace is remembering the general meaning of the information. The gist trace representations last, alone the verbatim trace representations leads to more forgetting. Flavell, Beach and Chinsky (1966) studied rehearsal in 5 family, 7 twelvemonth and 10 category olds. Each age throng had 20 children, who were all given a set of 7 pictures. The children were told to sieve and remember some of the pictures. After a 15 souths gap, the children were asked to say clamorously the pictures they could rally. During the 15 seconds gap a lip reader assessed what they believed each children mogul have been saying to themselves. They pitch that two of the 5 division olds, more than half of the 7 year olds, and most of the 10 year olds recurrent the pictures to themselves. It was found that rehearsal lead to better mobilize. Flavell et al. (1966) found that age differences may show the developme nt of strategies used, much(prenominal) as rehearsal. Although some of the children may have been apply rehearsal strategies, but may non have move their lips. McGilly and Siegler (1990) carried out an extension on Flavell et al.s (1966) study, by also asking children to cover up how they remembered the pictures. They found a high amount of children (74%) subject fielded using rehearsal strategies. However only 39% were observed, by lip reading techniques, using rehearsal strategies. wherefore suggesting that children of all ages use rehearsal, notwithstanding it may non be as effectively used in young children (Smith, Cowie Blades, 2003). This would apologise age differences in draw back in Flavell et al.s (1966) study. Ornstein, Naus and Liberty (1975) compared the rehearsal strategies of 7 year olds and adults. Participants were given a countersign to remember every 5 seconds, and asked to say aloud what they were thinking. They found that children repeated the word until the next word was given, then they would repeat the next word. Whereas adults repeated the word until they were given the second word, then they would repeat both words. Therefore showing that adults effectively used organization, but 7 year old children did not use this at all. This is primal in showing that children use rehearsal strategies, but they leave out the knowledge of how to effectively use such strategies.A study by Naus, Ornstein and Aivano (1977) taught 8 year olds a strategy of rehearsing in groups of three. They found that the 8 year olds could recall the same amount as 12 year olds, subsequently being taught the chunking strategy. Therefore jr. children can do this, but the organization of rehearsal does not occur naturally at these ages. Organisation, or chunking, is the grouping of information in an effective way to help with encoding. Moely, Olson, Halwes Flavell (1969) showed children a set of pictures that were in a random order in laid out in front of them. The set included pictures of animals and furniture, for example. The children were instructed to learn all the pictures and if it helped them they were allowed to rearrange the pictures. It was found that the children of 10 geezerhood and older had effectively used organisation strategies, as 10 year olds had categorised pictures correspond to whether it was an animal, or a piece of furniture, etc. As with rehearsal strategies, the younger children were not effectively using the organisation strategy. The children use this strategy, but do not seem to have developed knowledge of how it is best to be used, like the older children had.Elaboration is the strategy when wad make associations between given information to help with encoding and the subsequent recall of this information. Foley, Wilder, McCall and train Vorst (1993) gave 6 and 9 year olds verbal images to help them to recall pairs of words. The childrens recall was better if the image was basic, yet memorable. P ressley and Levin (1980) found that children of 7 years could use elaboration if an effective image was given with the pair of words, of which one was position and the other was its Spanish equivalent. This led to children learning the words better. Therefore children can use elaboration as an encoding strategy when given support, but the use of elaboration by themselves had not yet developed fully. As Buckhalt, Mahoney and Paris (1976) found when children first begin to use elaborations they use simple, unchanging elaboration, whereas older children use active elaborations. Active elaborations are images that are characteristic and therefore remembered better, allowing for a better recall.Leichtman and Ceci (1995) studied the reli tycoon of childrens testimony. The study was set in a preschool, where a stranger, surface-to-air missile Stone, came in for a day. near of the children were then given suggestive hearings every week for four weeks after. altogether of the children were interviewed on the fifth week, by a new interviewer, who had not seen surface-to-air missile Stone or any of the previous interviews. The children were firstly asked for a report of what happened on the day of Sam Stones visit, and then asked questions. The leading questions had led a high majority of the 3-4 year olds to make false claims, although the 5-6 year olds were slight likely to do this. Therefore younger childrens encoding is effected by what is inferred by other people, for example the leading questions in Leichtman and Cecis (1995) study inferred that Sam Stone had done something wrong, this lead to 72% of the 3-4 year olds saying he had done it, and 44% even claiming to have seen him do it. The older children were not affected by the leading questions as much, therefore showing that the encoding for the older children may have been better as they felt effective in what they could recall. Retrieval strategies are the ways in which people recall information from l ong-term memory. Kreutzer, Leonard and Flavell (1975) studied how 5 and 10 year olds would cure information from long-term memory. They used a story and asked the children how they could remember the answer. Kreutzer et al. (1975) found all 10 year olds could think of one way at least, whereas only half the 5 year olds could do this. Therefore the 5 year olds had not all developed effective retrieval strategies. Kobasigawa (1974) used 24 pictures, from 8 categories, for children of 6, 8 and 11 years of age to learn. along with the pictures the children were shown 8 pool stick cards, one for each category. Later on the children were shown the inform cards and asked to recall the earlier pictures. A third of the 6 year olds used the cue cards, whereas most of the older groups did this. The 11 year olds only effectively used the cue cards, by using them to help take in all the pictures they could remember from that category. The 6 and 8 year olds who used the cue cards, only named one picture from each category. Therefore suggesting that the 6 year olds had not developed the knowledge of how to use cue cards. The 8 year olds knew to use the cue cards, but they didnt know exactly how to use them. Therefore full knowledge of the usefulness of cue cards must develop later on, as the 11 year olds could use them effectively. Retrieval cues, such as cue cards, are strong aids to recall, according to Nelson (1990) people have no early memories because verbal cues are used as retrieval cues. Simcock and Hayne (2002) assessed the language skills of infants of 27, 33 and 39 months, and then tested the infants verbally and non-verbally. The infants were then tested on their recall at 6 or 12 months later. Simcock and Hayne (2002) found retention on both verbal and non-verbal recall, however non-verbal memory recall was better than verbal. They also found that verbal recall reflected the verbal abilities at the time of encoding, therefore showing that encoding is importa nt in the recall of information.Overall many of the basic processes are seen at birth, and are crucial from the early days. Memory strategies develop from the second year, but only pay back predominant between 5 to 7 years old, these strategies include rehearsal, organisation and elaboration. With age comes the development of quality, frequency, flexibility and the effective use of these strategies. Changes in the efficiency with age of encoding can be seen, as at the age of 2-5 years children can hold from 2 to 4 pieces of information in short-term memory, and at 7 years this is increase to 5 pieces of information. This is through the effective use of rehearsal, as this helps the child to become better at registering information as well as organising it and therefore helping to make storage and retrieval easier.Meta-cognitive skills refer to knowing that you know. unverbalized knowledge of meta-cognition skills can be seen later on in infancy, whereas pellucid knowledge develops from the age of 5 to 15. In general children under-report, therefore circumstantial questioning leads to greater reporting and prevents the information from decay. To increase retrieval of information in infants it is important to encourage them to think deeply about what they are being asked to remember (Butler, Gross Hayne, 1995). The phrasing of the question can distinctly lead children into the answer they think the interviewer wants, as Leichtman and Cecis (1995) study has shown.An important state to study in memory is forgetting, as a lot can be learnt about memory from what is not remembered as well as what is. For example, Hartshorn et al. (1998) found that infants aged between 2 and 18 months exhibited retention after the shortest test delays. They also found as the interval increased the younger infants were the first to forget, this is determined by project. This study shows that forgetting is affected by experience therefore what is remembered must also be affected by experience. look into into memory development in infants needs to take into account the biological side, as the brain is still changing and developing itself and plays a immense role in memory.ReferencesButler, S., Gross, J., Hayne, H.
