  • Data are ranked by their aversiveness (combination of valence and arousal) as shown in fig 2. For each warning picture the numbers denote the average valence and arousal scores, respectively. Valence range: 0 (neutral) to −4 (extremely unpleasant). Arousal range: 1 (low arousal) to 9 (high arousal).
