The psychological role of music and attentional control for religious experiences in worship.
Quarterly journal of experimental psychology (2006) December 1, 2022 Yoshija Walter, Andreas Altorfer
Worshipping with religious songs leads to a stronger felt presence of God than worshipping with secular music. In 60 believers, the ability to focus on God was positively linked to the intensity of the subjective religious experience. Choosing one's own worship songs produced a slightly stronger experience than using researcher-provided songs, but this difference was not statistically significant.
