  • 1. George Miller had a theory that our short term memory can hold 7+/ -2 pieces of information. This could be names, numbers or even chunks of information such as dates.<br />Take it in turns to try the activity below with a relative or friend to see how much information you can both hold in your short term memory. -Are you both within the normal range according to Miller?<br />Choose who will be the participant and who will be the experimenter.<br />Experimenter one: Use the numbers that are listed below for the experiment. Do not show them to the participant. <br />INSTRUCTIONS:<br /><ul><li>Ask if the participant is ready. Read out the lines of numbers one line at a time in a flat, steady voice. </li></ul>-Do not speed up or slow down and do not repeat the line. Once you have read the line to them, say ‘GO’ and they must repeat it back to you instantly. <br />2) Do this with each of the 14 lines.<br />3) If they get every number correct and in the right order, put a tick next to that line. If they get it incorrect, put a cross.<br />4) Read the lists on the left first and then the ones on the right. <br />2 1 3 6 5 7 8 9 0 8 63 5 4 6 7 3 5 7 5 21 4 5 2 6 5 8 9 34 6 5 7 8 2 3 4 9 4 6 1 2 8 73 5 9 8 1 00 3 7 1 28 3 7 9<br />7 5 3 6<br />8 7 5 3 9<br />2 5 9 1 0 6<br />2 4 5 2 8 6 5<br />1 3 4 7 6 5 8 9<br />5 3 7 6 1 3 8 9 0<br />0 4 7 2 3 9 5 1 8 4<br />9 3 5 2 6 7 4 5 8 9 0<br />Which was the longest line that they got correct? <br />Count how many digits are in that line. According to Miller’s theory, the majority of people will remember a maximum of 5 to 9 digits… Did your participant fit into this trend?<br />If you want them to test you, let them use the digits below. (DON’T LOOK OTHERWISE IT WON’T WORK PROPERLY! )<br />Experimenter two: Carry out the experiment in exactly the same way as your partner just did, using the digits below. <br />4 9 8 31 5 8 3 6 9 5 8 4 2 6<br />5 7 6 2 85 9 8 2 6 3 4 5 8 1 <br />3 5 9 8 6 22 7 8 5 9 6 4 5 2<br />1 4 3 5 9 7 34 3 2 5 9 8 6 7<br />4 3 5 8 9 6 2 13 9 5 4 8 1 5<br />5 9 5 3 8 6 4 8 27 5 8 6 4 2<br />7 5 8 2 9 6 3 5 4 35 1 7 5 8<br />9 4 5 1 3 5 6 7 8 5 23 5 9 2<br />
