Negative stimuli (e.g., angry face) are considered to be processed with higher priority. This priority is related to the rapid shifts of attention. However, the relationship between the processing superiority and negative emotional valence intensity has not been clarified. In this study, I investigated the effects of this intensity on visual target detection performance. In the experiment, participants were asked to discriminate one facial direction (first target: T1) and to detect one face (second target: T2) in presented successively eleven faces. T2 was three types: neutral, high, or low negative emotional valence angry faces. The results indicated that the T2 accuracies of angry faces were higher than neutral face. However, the performance did not differ between angry faces. Therefore, it is suggested that negative stimuli itself include the processing superiority regardless of the intensity of negative emotional valence.
