  • Essay / The influence of sleep on the accuracy of memory

    The influence of sleep on the accuracy of memoryThe aim of this study is to carry out a word memory which will explore the influence of sleep on accuracy of memory. The study examines the influence of sleep on false memories. This study looks at two things: (1) how does sleep improve word recognition? And if so, this would support the claim that sleep facilitates encoding in LTM. (2) How does sleep improve false word memory? According to Elizabeth F. Loftus (1996), false memories are often created by combining real memories with suggestions received from others; they can include words that we learn and associating them with semantic information. False memories are caused by our failure to recall the correct information. When we rarely store information, we retrieve it exactly the way it occurred, the inability to correctly recall information can lead to false memories. Sleep in false memories is measured by recall of words classified as previously studied, critical words which are the unstudied words, and critical words which were not previously studied but due to semantic association, they may appear during the recall process. Stadler, Roediger and McDermott (1999). A DMR paradigm is the tendency to falsely recall a target word from a list of words concentrated around that word. This causes people to falsely remember items that were never presented Roediger and McDermott (1995). In the DRM paradigm, word lists are constructed such that each given word is associated with a single unpresented word, treating it as a critical lure. For example, in this experiment to test participants' words such as letters, school, study, reading, pen, pencil, paper and pages, were presented, but their ratio...... middle of paper ... .. The items in the evening and the next morning, 12 hours later after their normal sleeping time, their memory for the items was tested. The sleep-free group studied and practiced the items in the morning, 12 hours later after their day of activity their memory was tested. The results showed that there was no significant difference between the two groups in word recall. Limitations of this study are that it uses a recognition technique instead of free recall, the small sample size, and not taking into account gender or ethnicity. (language is important in this case, especially when dealing with words that are not so familiar that it is difficult to remember them). In future studies, a larger sample would be relevant for a better result, do the test in a native language. language would help the participant remember better, look at the difference in gender, ethnicity.
