This study aims to determine if the act of voicing can have an effect on mood in a within-participant reversal paradigm, where each participant served as their own control. Following a baseline condition, participants underwent three experimental conditions: breathing, articulating, and voicing. Following baseline and experimental conditions, participants underwent an emotion-induction paradigm by looking at pictures. They rated their current mood and arousal levels following each picture. Additionally, psychophysiological measures of facial electromyography, electrocardiography, and electrodermal responses were gathered throughout the experiment. Results were mixed, revealing that there was a mood change during aversive picture viewing toward positive moods in the articulating condition and arousal levels were lower in the articulating and voicing conditions for positive picture viewing. However, the power to detect many of the results remained poor. Findings tentatively showed that the act of making speech sounds, not simply voice may influence the way we process emotions.
