Using Chunking to Increase Capacity of STM

The aim of the investigation was to repeat the experiment carried out

by Bower and Springston in 1970. A laboratory experiment was carried

out to demonstrate how chunking could be used to increase the capacity

of STM. Participants were presented with a letter sequence. The

independent variable was the chunking and the dependent variable was

how many letters the participants recalled. A repeated measures design

was used and the participants were an opportunist sample of 20

students, between the ages of 16-18 years. The results were analysed

using the Wilcoxon test.

Therefore the directional hypothesis that the participants remembered

more of the acronyms than the non-related trigrams is significant. The

graphs and the results extended this by showing that more acronyms

were remembered than the non-related.

Introduction

============

Memory is the process of storing information and experiences for

possible retrieval at

some point in the future. This ability to create and retrieve memories

is fundamental to

all aspects of cognition and in a broader sense it is essential to our

ability to function

properly as human beings. Our memories allow us to store information

about the world

so that we can understand and deal with future situations on the basis

of past

experience. The process of thinking and problem solving relies heavily

on the use of

previous experience and memory also makes it possible for us to

acquire language and

to communicate with others. Memory also plays a basic part in the

process of

perception, since we can only make sense of our perceptual input by

referring to our

store of previous experiences. Even our social interactions with

others are dependent

upon what we remember. In a sense it can be said that our identity

relies on an intact memory, and the ability to remember who we are and

the things that we have done. Almost everything we do depends on our

ability to remember the past.

  • A Rhetorical Analysis Of Chunking, By Ben Zimmer

    According to Ben Zimmer, in “Chunking,” many people greatly benefited from lexical chunks of words more logically and realistically. Zimmer claimed that at an early age, commonly set of phrases were memory enhancer and it actually improvised our ability to proficiently remember these sets of information because it gets processed and stored in our brain as single units. However, Zimmer also emphasized that one well-known critic was not favorable of lexical chunking because overstressing scripted words were not as effective as learning English language the usual and conventional technique such as: ordinary vocabulary, correct punctuation and proper grammar. Nonetheless, he believed that lexical chunking had been making a very promising approach

  • PMTCT Program Analysis

    276 Words  | 1 Pages

    The PMTCT program was a success not because of the intervention itself but because of the activism that employed specific and nuanced measures in repealing detrimental cultural understandings of disease. The pilot program in Khayelitsha went on to inform further programs in other predominately black townships. However, it has been proven over time that Khayelitsha is an exceptional case and not the norm. If anything, Khayelitsha proves the importance of the social and anthropological conceptions of disease within the context of health interventions. Interventions in an ethnic context must keep in mind the many intricacies that go in line with being infected and being of a certain identity and the history of that disease within that region.

  • General Support for Class Size

    3087 Words  | 7 Pages

    “Of course class size is important. You have to find the child before you can teach the child (Archived… 2000).” Though this opinion may seem radical to most people, you can see the underlying theme in the argument. Smaller classes allow students to have more personalized, individual attention from teachers. Many teachers and smaller class size advocates believe that such classes will allow for more constructive group activities, strengthen students’ problem solving and critical thinking skills, and accommodate for a wide range of learning paces. These advocates also believe that a reduced student to teacher ratio will give teachers more time to be innovative and develop new ideas, lead class discussions to further understanding, and give more practice exercises. For parents who want the best education for their children, these proposed effects of small class size make you wonder where the hard evidence is to back them.

  • Running Record Analysis

    Through conducting Connor’s Running record, I learned that he is developing well as a begging reader. I assessed him using a book The Wheels on the Bus that was above his grade level, and the book was considered an instructional level for him based on his 90% accuracy. He is a kindergartener, meaning that he has had little experience reading and has room for improvement, however he is developing into a successful reader. Connor still needs to improve his comprehension due to the fact that he rarely used meaning or structural clues to help decode unknown words. I also learned that Connor is very successful in regards to identifying sight words. Every time that he read a sight word, he seemed confident and enjoyed coming across a word that he knew. Repetition throughout a text is something that works well for Connor’s reading ability, because he is also good at recognizing words that he has already read. Connor is developing fairly quickly for a kindergartener and the Running Record allowed me to assess his strengths and weaknesses to guide further instruction for his continued reading development.

  • Non Cued Recall Essay

    Participants were split into two conditions, participants in condition one were presented with a word list and then asked to recall as many as possible (free recall). In the second condition, researchers presented the same words but as part of a story (cued recall). The results displayed that participants had better recall in the second condition because they had categorised the words according to the story. The results suggested that the children used chunking and recalled items according to categories. It was concluded that memory processing was improved due to categorisation, chunking and cued recall.

    The first issue that needs to be addressed however is what exactly is memory? “ Without memory we would be servants of the moment, with nothing but our innate reflexes to help us deal with the world. There would be no language, no art, no science, no culture. Civilization itself is the distillation of human memory” (Blakemore 1988). The simple interpretation of Blakemore’s theory on what memory is that a person’s memory is at least one of the most important things in their life and without it civilization itself could not exist.

    One explain dual processing as  of cognitive neuroscience's attempts to explain consciousness says that conscious experiences are produced by the synchronized activity in the brain.A stronger stimuli engages other brain areas, while a weak stimuli may only trigger a short visual cortex activity. Cognitive neuroscience explains dual processing as the idea that our brain includes a conscious cognitive process but also an unconscious automtic process we are not as aware of. One example of when my mind went on autopilot is when I play guitar. When I have  piece completely memorized, and my hand has grown accustumed to the sequence of notes, my hand automatically plays the notes without me consciously thinking about it.

  • Memory

    Memory is the tool we use to learn and think. We all use memory in our everyday lives. Memory is the mental faculty of retaining and recalling past experiences. We all reassure ourselves that our memories are accurate and precise. Many people believe that they would be able to remember anything from the event and the different features of the situation. Yet, people don’t realize the fact that the more you think about a situation the more likely the story will change. Our memories are not a camcorder or a camera. Our memory tends to be very selective and reconstructive.

  • Experiment On The Effect Of Chunking On Memory Retrieval

    515 Words  | 2 Pages

    In this experiment, the effect of chunking on memory retrieval will be explored. The aim of this research is to see how chunking in well-known terms would affect the way we encode information into our memory. The experiment investigated the effects of chunking on the capacity of STM (shot term memory) on cognition. The cognitive process involves the encoding, storage, and recall of information. Through this reason we can store newly acquired information and use prior knowledge.This experiment will be a based on research made by George Miller (1956). Miller demonstrated his theory in Short term store being limited by space, however, allows increase in capacity with smart methods such as chunking. He further looked upon studies relevant to chunking. By using Claude Shannon’s mathematical theory of information being measurable, Miller’s calculations showed that on average people could remember a string of plus or minus seven figures (letters or numbers) and only four or five words. Chunking is a technique where numbers and letters are grouped into units, more effective when meaningful.

  • Short Term Memory Psychology

    1775 Words  | 4 Pages

    As presented in past research, as people age, memory can become difficult when trying to recall certain things from the past or present. Everyone has different amounts of capacity and different ways of memorizing everything on a daily basis. Furthermore, short-memory can then become into long-term memory if something was presented again to that person in a later future. Two ways to memorizing information such as numbers, could possibly be done by either rehearsing or chunking the digits. Chunking digits has been done for many years by many participants that were part in digit span studies according to many researchers. In addition, short-term memory is very limited and can hold only certain amount information which can actually turn into long-term memory eventually.
