the effect of music and age on STM (WM). The results of the experiment were confirming the hypothesis to some extent.

Also the subjects will be distracted when the music is played. However‚ some of the results did not match the hypothesis; such as Group2 (Year 9 Newman) that completed the task and reached a higher level with the
