In class we did experiment on rats and we had three different conditions- C-Control B-Rock A-Classical music. We wanted to see if music had a difference in the amount the rats lever pressed. I need 3 Psychology articles spurces( not Blogs) that have done this testing. The overall findings was that it showed it didnt make a difference of the conditions. Since they were water deprived our rate was pressing more in the beginning so we had more counts.
