This study aims to examine the effects of instrumental lo-fi background music compared to silence on cognitive interference performance among university students. Participants will be randomly assigned to either a lo-fi music condition or a silent condition while completing a paper-based Stroop Color-Word task. The main outcome will be the level of cognitive interference, measured by the number of correct responses during the interference condition. The study seeks to determine whether background music improves or impairs selective attention and cognitive control.
