The first section is the sensory memory. Information is detected by the sense organs (sight and hearing). Information can be picked up by sight which is called iconic store, and information picked up from sound is called echoic store. Sensory memories only last just long enough for them to be transferred into the short term memory. The duration of this section is ¼ to ½ a second.
Murdock (1962) Murdock presented participants with a list of words at a rate of about one per second. After he showed them the words, the participants were required to recall as many of the words as they could. Murdock found that the words did not have an equal chance of being recalled and that some words, especially those that appeared first and those that came up last in the list, were better recalled than those in the middle. He called this serial position effect. The superior recall of items at the start of the list is called the primary effect, whilst the superior recall of the items at the end of the list is called the recency effect.
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.
So there are some confounding variables that can alter your ability to remember some words, rather than just rehearsal, or attention, as suggested in the multi-store memory model. Of course, this experiment lacks mundane realism, but tested many Participants, and produced quantative data, in controlled laboratory conditions, such can be considered to be
* Example of LTM: Childhood memories Short Term Memory (STM) | Encoding | Acoustically encoded: sound area of brain is activated during processing. | Research | Conrad (1964) presented participants with a visual series of 6 letters. They were asked to recall from STM and there was a tendency to confuse letters such as ‘b’ and ‘p’, relating the majority of the errors to similar-sounding letters. Participants must have therefore been using an acoustic code, converting the visual representation of the letters into sounds. |
Storage refers to the retention of this information. Finally, retrieval is the recovery of information stored in the brain. Memory is often split into sensory memory, short-term memory (STM) and long-term memory (LTM). Sensory memory refers to memory that is retained for a very short amount of time, normally less than 5 seconds. Iconic memory is visual memory, whereas echoic memory refers to sounds.
Completed on Sunday, 15 April 2012, 07:19 PM Time taken 53 mins 56 secs Marks 7/12 Grade 6 out of a maximum of 10 (58%) Question 1 Marks: 3.0 Given: The bottom motor starts first, and the top motor starts up after the bottom motor reaches full speed, and the client has no specific time delays in mind for the most downstream relays. Also the TMS steps available range from 0.05pu to 1pu in steps of 0.05pu. Calculate the Plug Bridge Settings for Ctop and C bottom: Choose one answer. A. PBS Ctop = 0.5 pu, PBS Cbot = 0.5 pu B. PBS Ctop = 1.25 pu, PBS Cbot = 1.0 pu Correct well done! C. PBS Ctop = 1.25pu, PBS Cbot = 1.25 pu D. PBS Ctop = 1.0 pu, PBS Cbot = 1.0 pu The most important thing to get this section correct is the correct calculation of I start from the given motor
Thin Slicing Life In the novel “Blink” by Malcolm Gladwell, thin slicing is used as a tool in life to make “snap-decisions” from one’s unconscious state of mind. This can be more effective rather than a complex thought process. In the classroom is where I feel I come in contact with thin slicing the most. When a difficult or random question is asked, occasionally I would get an answer right away but I wouldn’t think it was right. In that situation I would find out that my answer was actually correct.
As Jones, Rock, Shaver, Goethals, & Ward’s (1968) results showed, when marking another person’s exam paper primacy effects can occur. Several other studies have also showed differing levels of primacy and recencey effects (Costabile & Klein, 2005; Smith, Greenlees, & Manley, 2009). Research also tells us that those that are highly motivated to think, will be less susceptible to the bias of order effects (Ybarra, Schaberg, & Keiper, 1999). This present research seeks to investigate whether primacy effects will occur using an end of sequence method. Also, whether primacy effects would be reduced, or non-existent in people that are highly motivated to think, compared to those that are not.
Three stages of memory The three stages of memory consist of sensory memory, short term memory, and long term memory. Each stage has specific functions in how its stores memory, for how long, and when that memory is called upon. Sensory memory lasts about 1 - 2 seconds and is the immediate perception of stimuli in the environment. You can either dismiss that perception, or transfer it to short-term memory or perhaps long-term memory. Sensory memory is often divided into iconic (visual input) and echoic (sound) memory.
