An example would be: I look up a part number and remember it long enough to order one. Many of your short term memories are forgotten, but if enough attention is given some of these memories can be taken to the next stage. Long term memory is the continuous storage of information. Freudian psychology, calls this the preconscious and unconscious. Most of the time you are not aware of what memories are being stored, but can be called upon at a later time.
From short term memory to long term memory rehearsal was needed otherwise it would not be entered. Sensory memory is divided into the 5 senses, Iconic, Echoic, Gustatory, Olfactory and Haptic. In sensory memory the information is stored for 1-2 seconds approximately and if it is not given attention it decays. Short term memory lasts for about 30 seconds and can hold around 7 + or – 2 items. If this information is not rehearsed then it will decay and not be entered into long term memory.
Short term memory allows us to hold onto information long enough to use it. It deals with new data from the sensory memory and old information retrieved from the long term memory. It has duration of 18 seconds but this can be longer if the information is rehearsed, this is usually done acoustically. The short term memory has a limited capacity so information is often lost when new data comes in, this can be reduced by ‘chunking’ information (grouping info together). Long term memory is a more permanent store; we retrieve past experiences and knowledge from it.
This information once in the short term memory will remain here for a few seconds unless it is rehearsed or displaced as new memories get received. If information in the short term memory is actively processed, through rehearsal, then it may be transferred to the long term memory, where it will remain for a lifetime unless interfered with or lost through decay. Evidence, such as Rajan Mahadevan, suggests that the long term memory and the short term memory operate differently. In this study it is said that Rajan could remember 31,811 digits of PI, but with simple tasks like going shopping he would still have to write a grocery list like anybody else would. The multi store memory concluded that the short term memory and long term memory operate differently in terms of; capacity, duration and encoding.
Outline and Evaluate the Multi-Store of Memory The idea of a multi-store memory, was discovered by Atkinson and Shiffrin in 1968, and argues that memory can be divided into three separate structures; Sensory memory, Short-term memory and Long-term memory. Information is thought to enter the memory system through the Sensory memory, then passed on to the Short Term memory when attention is paid to it. If this information is thought about and rehearsed in the Short Term memory it is passed to the Long-Term Memory to help interpret information in Short Term Memory. The Sensory Memory, which is uses visual, auditory and tactile encoding, has a limited capacity however, and a brief duration, so for information to be useful, it has to be passed
Memory is a hypothetical construct in that we know of its existence but we cannot physically see it, it can be described as a ‘the retention of learning or experiences’. Memory is an important part of the learning process, without which experiences would be forgotten and we would not be able to benefit from previous experiences we have had. Unless prior learning can be recorded, it cannot be used at a later date. Early research was constructed by Ebbinghaus (1885) suggested that his own limit for containing memory was 7 items; this was later supported by Miller (1956) with the ‘magic number 7 plus or minus 2). The nature and structure of memory is often referred to two types of memory, Long term memory (LTM) and Short term memory (STM).
Trace decay theory states that forgetting occurs as a result of the automatic decay or fading of the memory trace. Trace decay theory focuses on time and the limited duration of short term memory. No one disputes the fact that memory tends to get worse the longer the delay between learning and recall, but there is disagreement about the explanation for this effect. According to the trace decay theory of forgetting, the events between learning and recall have no affect whatsoever on recall. It is the length of time the information has to be retained that is important.
In the first experiment, the task required participants to read the written color names of the words separately from the color of the ink (for example, the participants would read “red” no matter what color the ink was). In the second experiment, participants were required to say the color of the letters separately from the written word with the second kind of stimulus and also name the color of the dot squares. If the word “red” was written in blue, the participants would have to say “blue” and not red. In Stroop’s third experiment, the participants were tested at different stages of practice at the tasks and stimulus used in the first and second experiments, to account for the effects of association. John Ridley Stroop concluded that participants took much longer to complete the color reading in the second task than they
The research carried out allowed us to confirm that using the method of loci would improve and an individual’s recall. Introduction The Multi-Store Model (MSM) of Memory was proposed by Atkinson and Shiffrin in 1968 and claimed the memory system contained three structural components. Sensory memory (SM) stores information that is collected by our senses (sight, smell, hearing etc.). This information is received continually but the majority is ignored and only stored for a brief moment of time. At this point it is either disregarded or transferred to the short term memory (STM) store.
Encoding How information is stored and processed, for example sounds, visual and meaning. Capacity How much information can be stored. Duration How long it lasts, for example a few minutes to a lifetime. Explain how the encoding, capacity and duration of memory have been measured. Short Term Memory (STM) and Long Term Memory (LTM): Aspects and Research | Encoding | Capacity | Duration | Short Term Memory (STM) | Acoustically encoded: sound area of brain is activated during processing.
