Violent lyrics in songs increase aggression-related thoughts and emotions and could indirectly create a more hostile social environment, a study released on Sunday by a U. S. psychology association found. The Washington D.C. -based American Psychological Association (APA) released the study, resulting from five experiments involving over 500 college students, in the May issue of the Journal of Personality and Social Psychology.
The violent songs increased feelings of hostility without provocation or threat, according to the study. It said the effect was not the result of differences in musical style, specific performing artist or arousal properties of the songs. Even the humorous violent songs increased aggressive thoughts, the study said.
The group said the study contradicts a popular notion that listening to angry, violent music actually serves as a positive catharsis for people.
