Abstract

The purposes of this study were to examine the effects of noise-masking on performance and psychological responses. Because task complexity is to moderate the effect of noise-masking, this study was to testing interaction effect of noise-making and task complexity. Subjects in this study were 120 students who participate in introduction to psychology. All subjects were assigned to randomly in 6 experimental condition(control noise/simple task, official noise/simple task, masking noise/simple task, control noise/complex task, official noise/complex task, masking noise/complex task). According subjects were finished task, dependent measures was saved automatically in database. The results indicated that main effects of noise and task were significant and interaction effect was also significant on task performance. However, main effects of noise and task were significant on psychological responses but interaction effect was not significant. Based on these results, introduction to masking noise such as white noise will contribute co prevent irregular noise and co increase performance.
