This ICIS deliverable concerns the research proposal as accepted by the Radboud University Nijmegen and the DECIS Lab/TRT-NL and the first results of pilot studies regarding the effect of music to influence the mood of participants. The first pilot study revealed that males react differently to music as mood manipulation than females, that is, males are less affected by music as a mood manipulation. The second pilot study was intended to disambiguate the male response from social-unwillingness to discuss their mood versus no effect at all of the music as mood manipulation. The method to measure mood implicitly, however, did not seem to be a reliable measure. However, the explicit measure revealed a difference in negative feelings for both males and females for the two different mood manipulations (happy vs. sad music).
