Music is not only able to affect your mood. Listening to particularly happy or sad music can even change how we perceive the world, according to researchers from the University of Groningen.
Music and mood are closely interrelated. Listening to a sad or happy song on the radio can make you feel sad or happy. However, such mood changes not only affect how you feel but also change your perception. For example, people will recognize happy faces if they are feeling happy themselves.
A study by researcher Jacob Jolij and student Maaike Meurs of the Psychology Department of the University of Groningen showed that music has an even more dramatic effect on perception: even if there is nothing to see, people sometimes still see happy faces when they are listening to happy music and sad faces when they are listening to sad music.
