  • The Memory Theory Of George Miller's Short Term Memory

    George Miller’s magical number 7, plus or minus two, helps confirm the capacity of short term memory (Miller, 1956). Most people 18 and over can hold 5 to 9 items in their short term memory (Miller, 1956). Miller believed that short term memory could only hold his magic number because of the limited “slots” in which memory could be placed in the brain. Miller reached this conclusion by getting the participants of the initial study to listen to a number of tones that were different by pitch. Every sound was produced solely, and the participant was asked to match each sound corresponding to the other tones that they had already heard. This was done by giving each sound a number. When the experiment ran on through around 6 or 7 tones, the participants…

  • Introduce Memory Analysis

    Introduce memory The analysis of human memory spans as far as 2000 years ago to Aristotle 's efforts to comprehend memory in his thesis "De Memoria" (Bloch, 2014).

    hand. One of these techniques includes studying using online games that are set up as quizzes in order to be constantly exposed to the information in a more entertaining fashion. Mini quiz games such as “Quizlet,” “Kahoots”, or “Quizizz” may be beneficial study methods because they provide visual and repetitive strategies that can help incorporate information into working and short term memory in order to recall the information at a later point, possibly during a test or exam ("Quizlet", 2016;…

  • Baddeley And Hitch: The Working Memory Model

    The working memory model, as introduced by Baddeley and Hitch in 1974, outlined two distinct components: the phonological loop (PL) which deals with auditory information, and the visuospatial sketchpad which is concerned with visuo-spatial data. The PL consists of two parts, the phonological store and the articulatory control process (ACP). According to Baddeley and Hitch, auditory information is held in the store for about two seconds while the ACP recycles this information, through…
