The participants have the task of recalling 11 digit mobile phone numbers. 5 of these mobile phone numbers will be chunked and another 5 will be un-chunked. They have to listen to the voice recording of the mobile phone numbers being read out one at a time and then try and recall the numbers in the correct order aloud after each one is read out. Procedure Each participant was sat down on a bench in an empty patio outside. This was the only available space to conduct my experiment where there were no other people. I then briefed the participant on what they would have to do in the experiment.

Participants where assured of confidentiality, see briefing in appendix. I then began the test by first playing the 5 un-chunked numbers one after the other with gaps in between each mobile number so the participants could say their answers. Then I played the chunked numbers one after the other with gaps in between each mobile number so the participant could say their answers. I wrote sown their answers as they said them. At the end of the test I thanked the participant and asked them if they had any questions. After that they were free to go.

Confidentiality – Before each participant does the experiment I will explain that their results will be taken attached to their results. I will also say that if at any time they decide to withdraw from the forward in confidence and none of their personal details e. g. name, date of birth, will be at experiment then they can do so and their results will be destroyed. There was an ethical brief and debrief before and after my experiment. The wording for the brief and debrief can be found in the appendix along with instructions for the task. Results

The two line graphs display the results of the chunked and un-chunked mobile phone numbers. As shown on average the chunked results show a higher amount of correctly recalled digits than the un-chunked. The mean score for un-chunked results was 21. 3 and the mean score for chunked results was 25. 5. Therefore the chunking method was more successful. Although participant 2 scored better in the un-chunked mobile phone numbers than the chunked but this could be down to boredom or loss of concentration as the chunked numbers were done second.

My hypothesis can be accepted there was a better level of recall when the numbers where chunked rather than un-chunked. So I succeeded in my aim of investigating whether chunking can improve the amount of information the short term memory can hold and found that it does. I have supported Miller’s theory. My results prove Ebbinghaus was wrong with his idea that the short term memory could only hold six or seven pieces of information as some of the participants in my experiment held more than that.

My experiment also supports Attkinson and Shiffrin’s idea that information is not rehearsed then it is forgotten. Summary and Conclusions My research could be taken on and used in the real world. For example A limitation of my experiment was that I only tested British people between the age of 16-18. Therefore my results haven’t got a very broad variety of different ages or cultures and are not very representative. These results only represent a very small group of people. I could have improved my experiment by drawing from a wider variety of different people.

Testing people of all different ages and ethnic persuasions would have given me a broader and more representative set of results. Further research you could carry out following my experiment is whether recall was better when hearing a recording of a woman’s voice a opposed to a mans voice. This would be interesting research as participants 1,2,4,5 and 10 on average got lower scores on both chunked and un-chunked than participants 3,6,7,8,and 9. Participants 1,2,4,5 and 10 were male and participants 3,6,7,8 and 9 were female.

So on average the girls got higher test results than the boys. Maybe this was because the girls found listening to a man’s voice more appealing and therefore found it easier to remain focused. Maybe the male participants found the man’s voice less appealing as opposed to a woman’s voice and therefore found it more difficult to remain focused. So would the male participants overall recall improve and the females recall overall deteriorate if it was a recording of a woman’s voice?

It is a simple memory test on mobile phone numbers. I will play you a voice recording of ten different 11 digit mobile phone numbers. After each mobile phone number is played there will be a pause for you to recall and speak as much of the mobile phone number as you can remember. I will then record your results on this sheet. No personal details will be attached to your results and they will be treated with strict confidentiality.

If at any time during the test you would like to withdraw from the experiment you can do so and your results will be destroyed. Instructions You will hear ten 11 digit mobile phone numbers one after the other. In between each mobile phone number I will stop the tape to give you time to recall and speak as many of the digits you can remember in the correct order. As you speak the digits I will record your results onto a results sheet. When I have finished writing your results down I will restart the tape and the next mobile phone number will be played. Debrief

Thank you for taking part in my experiment. Do you have any questions? [L1]The abstract is a single paragraph, prose, extremely brief statement of what is to be found in your report. It has to mention seven things: Main study under review, aim, hypothesis, research method, whether you were able to accept your hypothesis, what comment you have made about your key research as a result, and lastly what real world conclusion you have made. Everybody does the abstract badly, so I will want to see it in order to comment on it. The abstract should be the first page after the title page. It should be SHORT.
