The Effect of Music on Performance of a TaskAbstractIn order to investigate whether music affected performance of a task,and experimental technique was used, variables were manipulated anddata recorded.
The aim of this study was to investigate whether different musicstyles affected the performance of a task. It was a novel experiment,only loosely based on previous research dating back to the 19thcentury.
The method involved three groups of participants undertaking a test(solving thirty anagrams). One group had fast music in the background,one had slow music and the third performed it in silence. Theparticipants were primarily selected via a systematic sample, but thiswould have been changed to an opportunity sample had some participantsnot turned up.
It was hypothesised that there would be significant differencesbetween a) fast and slow music, b) fast and no music and c) slow andno music.
A two-tailed Mann-Whitney U test at a significance level of p=0.05revealed that all three alternative hypotheses were accepted and nullhypotheses rejected.
The data collected illustrated that having slow music playing in thebackground improved performance of the task compared to performing itin silence, while fast music worsened performance.
The implications of this study, its limitations and suggestions offollow up studies will be further discussed.
Social influence describes how other people around us can influenceour actions. It is especially relevant in situations where groups ofpeople are performing a task together, as discovered by Triplett inone of the …
… Observed value of U = 30
Critical value of U = 23 at a significance level of p? 0.05 and atwo-tailed test. Therefore, as 30> 23 the null hypothesis isrejected.Appendix VI – Mann Whitney U Test for Hypothesis TwoU = 10 x 10 + 10 (10 + 1)2 – 111.5 = 43.5 U = 43.5
U’ = 10 x 10 – 43.5 = 56.5 U’ = 56.5
Observed value of U = 43.5
Critical value of U = 23 at a significance level of p?0.05 and atwo-tailed test. Therefore, as 43.5> 23 the null hypothesis isrejected.Appendix VII – Mann Whitney U Test For Hypothesis ThreeU = 10 x 10 + 10 (10 + 1)2 – 115.5 = 39.5 U = 39.5
U’ = 10 x 10 – 39.5 = 60.5 U’ = 60.5
Observed value of U = 39.5
Critical value of U = 23 at a significance level of p? 0.05 and atwo-tailed test. Therefore, as 39.5> 23 the null hypothesis isrejected.
