Whether the Amount of Noise in an Environment Affects an Individual's Ability to Memorize Words in a Limited Amount of Time
Hypothesis-???-In a noisy environment, fewer words will be memorised, as it will beharder to concentrate and memorise words.Method-?-DesignThe type of experiment we did was a lab experiment as it wascontrolled, as the participants knew they were taking part and also wecontrolled the locations in which the experiment took place.
This was a good thing, as we wanted fair and accurate results, which came from an experiment in which we controlled the conditions. The locations we used were the cafeteria for the noisy environment as it is constantly filled with noise and people and the learning centre for the quiet environment where there is absolute silence and no noise whatsoever. We used an independent measures design. We used different participants for the two environments as we wanted to avoid any order effects i.e. participant won?t get better through practice and participant is less likely to get bored. The independent variable in this experiment was the noise in the location and the dependent variable was the amount of words remembered. Participants I used 12 participants for this experiment. 6 for the noisy environment and 6 for the quiet environment. The sampling technique I used to select the participants used in this experiment was an opportunity sample as data is unlikely to be representative, as sample will probably not include all subgroups. The participants will be put into two groups and taken to their location where they?ll do the experiment. Materials The materials used were a list of words, a pen and a piece of paper the participants will write the words they remember. Procedure The participant will be asked for their consent for taking part and assured that if they don?t want to complete the experiment, then they are free to leave at any time. They are asked to write their sex, their age and the subjects they are studying on a blank piece of paper. They are asked to take a seat and given the list of the 20 words to memorise. They have 4 minutes to memorise as many words they can in that time. After time has run out, the list of words is taken back by the experimenter and a blank piece of paper and pen is handed to the participant and they are given a minute to write down the words they remember from the list. The same procedure was used for both the noisy and quiet participants. Results Tables to show number of words correctly remembered in the memory test. Noise environment Participants Sex Age No of words 1 Female 16 15 2 Male 17 12 3 Male 16 16 4 Female 16 15 5 Female 16 17 6 Female 16 12 No noise environment Participants Sex Age No of words 7 Male 16 18 8 Female 16 20 9 Male 17 18 10 Female 16 19 11 Female 17 20 12 Male 16 20 Mode, Median and Means Mode for no noise= 20 Mode for noise= 15 + 12 Median for no noise = 19.5 Median for noise = 15 Mean for no noise = 19.2 Mean for noise = 14.5 Discussion In this experiment my aim was to find out whether the amount of noise in an environment affects an individual?s ability to memorise words in a limited amount of time and from my results I can tell that it does. The findings back up my hypothesis and prove it correct. In the noisy environment, none of the participants remembered all of the words whereas in the no noise environment two of the participants remembered all of the words and were able to recall them correctly. Also, in the noise results the no of words recalled correctly ranged from 12 ? 17 whereas in the no noise results the results ranged from 18- 20. This shows that overall the amount of noise in an individual?s environment has a major impact on their memory and the amount of information learned in a short time period thus proving my hypothesis correct. A few problems were encountered while doing the experiment. First up, 4 minutes was too long for the participant as they got easily sidetracked and began to lose concentration towards the end of their time. Also I think 1 minute was too short time to give the participants to write down the words they remembered, as it didn?t give them enough time to recall the words. There was a number of ways in which I think I could?ve done better and thus perfected and got better results. I think we could have used a bigger sample giving us a bigger range of results, which could have been looked into more. If I were to carry the experiment, I would use 30 people in total, 15 for noise and 15 for no noise. Also I would make sure that they received 3 minutes to memorise the words and 2 minutes to recall and write then down. However memory is not a variable, which can be measured in the real world, memory depends on each individual. Although it can be said that noise does have a certain amount of affect on a person memory, this may not be the case with everyone.
