On being cool and collected: mood regulation in anticipation of social interaction.

This study examined the influence of anticipated social interaction on the regulation of moods. Study 1 induced happy and sad moods through exposure to music. All participants expected to perform a second, unrelated experimental task either by themselves of with another participant. Participants who expected to do the task alone subsequently selected positive and negative news stories equally, but those who expected to interact preferred stories containing material incongruent with their mood. Study 2 confirmed this outcome, but showed it was confined primarily to anticipation of interaction with partners who are expected to be in neutral or good moods themselves. In Study 3, participants whose mood was not manipulated reduced self-exposure to cheerful or depressing videos when they expected to interact with another.
