Correction: I-Space: The Effects of Emotional Valence and Source of Music on Interpersonal Distance

If the ongoing emotional state can actually change the attitude of the listener to the surrounding individuals and alter the perceived need of keeping a margin of safety against potential threats, we hypothesize that positive emotion-inducing music will ‘‘shrink’’ participants’ personal space, while negative emotion-inducing music will ‘‘expand’’ participants’ personal space. In a second experiment we also investigated whether the source of the music, being either an external source (i.e. music played through loudspeakers), or a source ‘‘embedded’’ in the listener’s ears (i.e. music played through headphones), will influence the change on the personal space representation.
