Valence and arousal ratings for neutral and emotional sounds.

<div><p>A) Valence and arousal ratings for neutral and emotional sounds as a function of group (DPD patients vs. patient controls). The center of the ellipses in the left and middle column represent the mean rating and the radii correspond to the standard error of mean (SEM). The values next to the ellipses depict mean and SEM for vividness ratings. The right column shows valence and arousal ratings collapsed across arousal categories as a function of group with error bars indicating SEM.</p> <p>B) Average differences to the norm ratings (Bradley & Lang, 2007) [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0074331#B30" target="_blank">30</a>]. The dots in the left and middle column represent mean norm ratings and the crosses depict average ratings of each group. The bars in the right column depict differences to norm valence and arousal ratings collapsed across arousal categories as a function of group with error bars indicating SEM. neut = neutral, neg = negative, and pos = positive sounds; -/+ indicate medium and high arousal, respectively.</p>
