Title: Effects of Emotional Visual Scenes on the Ability to Decode Emotional Melodies
Issue Date: 2016
DOI: 10.1109/ICTAI.2016.0124

Abstract: An effective change in Human Computer Interaction requires to account of how communication practices are transformed in different contexts, how users sense the interaction with a machine, and an efficient machine sensitivity in interpreting users' communicative signals, and activities. To this aims, the present paper investigates on whether and how positive and negative visual scenes may alter listeners' ability to decode emotional melodies. Emotional tunes were played alone and with, either positive, or negative, or neutral emotional scenes. Afterword, subjects (8 groups, each of 38 subjects, equally balanced by gender) were asked to decode the emotional feeling aroused by melodies ascribing them either emotional valences (positive, negative, I don't know) or emotional labels (happy, sad, fear, anger, another emotion, I don't know). It was found that dimensional emotional features rather than emotional labels strongly affect cognitive judgements of emotional melodies. Musical emotional information is most effectively retained when the task is to assign labels rather than valence values to melodies. In addition, significant misperception effects are observed when happy or positively judged melodies are concurrently played with negative scenes.
