Discussion:
In the results, it is shown that there is a higher percentage recall rate for those only looking at letters and not letters and numbers; this is promising information as it supports the hypothesis. It is also shown throughout the results that the maximum characters remembered was ten letters. It is interesting how it was letters and does not breach the ±7 concept proposed by Miller. Since it was letters, X U O B A V C I A Z, it fits the idea of recoding information to increase the size of chunks. Remembering the sounds and syllables of the letters could be used to increase the chunk size. For instance, the letters could be broken into XUO-BAV-CI-AZ and remembered using only four chunks opposed to 10, drastically decreasing the chances

There are differing forms of memory, three main forms are short, active/working and long term memories. Active is a form of memory used when recalling steps such as when baking and reading off a recipe. Short and long are named due to the duration in which the events seen are recalled for. Long term memory involves memories that have been stored in a more permanent place much like a hard drive on a computer. Short term memories are chunks of information that are only temporarily stored and without repetition and use of tactics to remember, will be …show more content…
Miller also suggests that short term memory last from 0 to 30 seconds. Miller goes on to talk about recoding of information and how it affects the process of memory. Since memory is fixed to a certain number of chunks to improve your memory capacity, and therefore increase the amount of information you can retrieve, you have to increase the size of the chunks. This can be done by using different methods to create bigger variations of information. Say someone is learning Morse code, initially every dot and dash is considered one chunk, but as you progress and learn each code for each letter then you will remember larger chunks. Eventually words will be learnt and consequently increase the size of information remembered. This is a tactic to increase short and active memory by essentially increasing chunk size, but not changing the core ±7 bits of
He author a paper that was one of the most quoted papers in the field. The Magical Number Seven, Plus or Minus Two, suggested new ideas about the way immediate memory works, stating that short term memory is limited to holding about seven “chunks’ of information. This limit applied to short term memory and other cognitive processes, like distinguishing different sound tones and perceiving objects at a glance. Chunking is a diverse phenomenon in psychology and cognitive science. Free recall amongst other tests can demonstrate “Chunking,” the task requires individuals to repeat items they had been previously instructed to study. The probability of recall is bigger when chunking is used. Chunking is considered a flexible way of learning. Miller observed that some human cognitive tasks fit the model of a “channel capacity,” but short term memory did not. An assortment of studies could recap by stating that short term memory had a capacity of about “seven plus or minus two chunks. Miller recognized that we are not very definite about what constitutes a chunk of information. According to his theory, it should be possible to increase short term memory for low information content successfully by mentally recording it into smaller higher information content. Chunking as a memory mechanism can be observed in the way we group number and information in our day to day life. Different kinds
Outline and evaluate research in to the duration, capacity and encoding information in short term memory.
Memory is the retention of information over time and it changes through our lifespan, from infancy through adulthood (Santrock 218). There are two types of memory, explicit and implicit.
Most adults can usually store between 5 and 9 items in their short-term memory. This idea was put forward by Miller, and he called it the “magic number 7”. He hypothesized that short term memory could hold 7 (plus or minus 2 items) because it only had a certain number of “slots” in which certain items could be stored. However, Miller did not specify the amount of information that can be held in each slot. This leads into the idea of “chunking”. Chunking refers to the
There are 3 necessary steps/types that are crucial to forming a lasting memory. Step 1: sensory memory, step 2: short-term memory, and step 3: long-term memory. These are the three types of memory that are needed to build a lasting memory. Sensory memory is the shortest memory in the shortest- term memory element.One of the types of memory allows you to remember information through the 5 senses. The brain will remember anything that happened from 1 second to 60 seconds using the sensory part of your memory. An example of sensory memory is: I got hit in the head with a purple yo-yo. After sensory memory comes the short-term memory. Short-term memory acts as a “scratch- pad” for temporary recall. Short- term memory holds small amounts of information. Anything something that took place in front of your eyes for longer than 60 seconds, the short-term memory section of the brain will remember it. This section of your brain will allow you to recall that information in the next few hours or days. An example of short-term memory is: time on the clock 10 minutes ago. Lastly, comes long– term memory. Long- term memory, is used to store information of a set time
Why do you think the author talks about doubling the capacity of short-term memory when in the rest of the article he talks about issues related to long-term memory?
Verbal short term memories encode and represent information in a phonological form in immediate memory. This was highly supported by Baddeley and Hitch’s (1974) working memory model. Baddeley and Hitch introduce the “phonological (articulatory) loop”, a mechanism in the short term memory which helps in the retention of verbal information temporarily. (Baddeley & Hitch, 1974). As these mechanisms are heavily dependent on the phonological systems, they have brought about inefficiencies in memory encoding bringing about various effects which includes phonological similarity effect ( difficulty in recall due to similar sounding words), word length effect (recall to be more difficult with long words than short words), the unattended speech effect
How does memory work? Is it possible to improve your memory? In order to answer these questions, one must look at the different types of memory and how memory is stored in a person's brain.Memory is the mental process of retaining and recalling information or experiences. (1) It is the process of taking events, or facts and storing them in the brain for later use. There are three types of memory: sensory memory, short-term memory, and long-term memory.
One of the oldest memorization methods is chunking. This is taking items into groups called trunks, so that they can easily be memorized. These way individuals can improve how they remember the items by their larger association. A common chunking example is phone numbers. It would be hard for an individual to remember single numbers 5-3-6-1-8-9-2 but it easier to remember 536-1892. This was the assertion of psychologist who believed that individuals could only store five (5) to nine (9) items, while having the ability to hold four (4) chunks of information. Therefore, chunking information increases the capacity of memory to hold more
Memory is a property of the human mind. It describes the ability to retain information. There are different types of classifications for memory based on duration, nature and retrieval of items.
Having short term memory is an important thing to have. Without short term memory we wouldn’t be able to recall things from only moments before. Short Term Memory is the ability to recall things from moments to days before. Imagine having a conversation with someone and then as soon as your attention is redirected you forget what you’ve just been told.
The type of information stored in memory is something that is really hard to do because sometimes people can retain information over time. There are different types of memory such as sensory, short-term, and long-term memory. Sensory memory involves many senses such as vision, hearing and initial processing. Short-term memory has many key processes like
Memory is defined as "the persistence of learning over time through the storage and retrieval of information." Our memory can be compared to a computer's information processing system. To remember an event we need to get information into our brain which is encoding, store the information and then be able to retrieve it. The three-stage processing model of Richard Atkinson and Richard Shiffrin suggests that we record information that we want to remember first as a fleeting sensory memory and then it is processed into a short term memory bin where we encode it ( pay attention to encode important or novel stimuli) for long-term memory and later retrieval. The premise for the three step process is that we are unable to focus on too much
Interference of other material also plays a role in the short-term forgetfulness. It is hard for the brain to focus on committing more than one thing memory at a time. The old stuff is bumped out by the new stuff, which is a big contributor to why you forget. Our short-term memory seems to have a limited amount of places to hold this temporary data. This is an area that has been studied a lot. There are different theories about how much we actually retain before it is pushed out by the next thought. Chunking makes remembering easier as well. It involves grouping information into familiar stimuli so it can be stored as a single unit. This takes up fewer memory slots and makes remembering smoother. The chunks are effective when they are associated with something familiar to the individual. This ties into the long-term memory because that is where you draw the familiarity.
Memory is the process involved in retaining, retrieving and using information about stimuli, images, events, ideas and skills after the original information is no longer present. We can relate this case with what we learn in psychology. Short term memory holds information from 15 until 30 seconds whereas long term memory holds information for years. Short-term memory (STM) is the system that is involved in storing small amount of information for a brief period of time while long-term memory (LTM) is the system that is responsible for storing information for long periods of time and recall information about past events in lives and knowledge learned.
