The Effect of Music Types on Mood and Vigilance (SBS thesis, Haigazian University)https://doi.org/10.62811/th.0045https://haigrepository.haigazian.edu.lb/handle/123456789/175A study was conducted to test five hypotheses which investigated the effect of music types on mood induction and vigilance in young Lebanese students. This study aimed also to validate a specific type of music 'the designer' as a tool for mood and vigilance enhancement. A mood assessment scale was administered to a sample of 60 students (31 males and 26 females), with ages raging between 13 and 18, enrolled at the Beirut Baptist School in Beirut. The mood shift was measured by comparing the posttests and the pretests T scores of the mood assessment scales. The vigilance was assessed by using the 'star-tracing' activity. Two tailed paired t tests and one way analysis of variance tests between-groups effects (the dependant variable being the mood and vigilance and the independent variable being the type of music), were performed. The results showed significant shifts in mood for all types of music, except for the designer music on the relaxation scale. As for the vigilance, there was a reliable difference between the influence of Designer music and Grunge Rock. The results indicate that music and in specific the 'Designer' can be used as a tool for facilitating reduction of stress and hostility and fostering attention and focus.
