Introduction

Tom Lowe Psychology Homework for 16/09/05 1. What is meant by the terms encoding, capacity and duration, in relation to short term memory. Encoding - When we see any material, we immediately begin top encode it. To encode material to store into short term memory, we encode it acoustically, this means we repeat the information/material over and over again, this is known as rehearsal. ...read more.

Middle

Psychologists generally say that the capacity of short term memory is about seven items, or between 5 and 9 items. Duration - The duration of short term memory is again very different when compared to long term memory. The duration of short term memory depends on if information is being rehearsed, if not the duration is generally a maximum of 18-20 seconds. ...read more.

Conclusion

To do this he presented participants in the experiment with a sequence of random letters and digits, he then asked for the participants to recall the sequence showed to them in the correct order. Jacobs found that the average number of items from the sequence recalled correctly was between 5 and 9. He also found that participants recalled digits better than letters. From these findings Jacobs suggested that the limited capacity of short term memory is between 5 and 9 items. ...read more.

    Baddeley et al found that participants could recall considerably more short words than long words, they were able to recall as many words as they were able to articulate in approx 2 seconds and that, finally, there was a strong positive correlation between reading speed and memory span.

  2. SHORT TERM MEMORY

    The participants will be given music to listen to for a period of a minute immediately after looking at the words. This group of people will then be asked for the recall of the words remembered. These will also be recorded.

  1. effects of chunking and unchunking on short term memory

    To overcome this effect counterbalancing is done. Counterbalancing uses the ABBA procedure; the participants are split into two groups by placing all names into a hat and randomly pulling out the first 12 names to form group one, this reduces the experiment effect. Group 1 do condition A followed by condition B; whilst group 2 do condition B followed by condition A.

  2. Investigation into acoustic and visual encoding in short-term memory

    when information is presented visually, this links into be the experimental hypothesis. Displacement and decay are the theories associated with this research. However the null hypothesis suggests there will be no significance or difference in participants using acoustic coding in STM and when information is presented visually to them.
