| Bruce and Young’s (1986) model posited that the processes underlying facial identity and facial expression recognition are independent. However, recent studies have shown some possible interactions between those processes [e.g. Schweinberger & Soukup, 1998, Journal of Experimental Psychology, 24(6), 1748-1765; Fox et al, 2008, Journal of Vision, 8(3), 1-13]. Relating to this issue, Takahashi and Yamada (2012) examined whether facial distinctiveness was affected by facial expressions, and reported that happy face could keep or maintain the distinctive properties of neutral face but sad face couldn’t. We examined the relationship using intensity of facial expressions. We used 168 images of twenty four persons’ face with neutral and six facial expressions (happiness, surprise, fear, sadness, anger and disgust) as stimuli and asked participants to rate intensity of those facial expressions. Comparing correlation coefficients between distinctiveness ratings based on Takahashi and Yamada (2012) and intensity of them indicated that the modest correlation coefficients were shown between intensity of surprise and distinctiveness in surprise, fear and anger images, between intensity of fear and distinctiveness in surprise and sadness images, and between intensity of anger and distinctiveness in disgust images. Those results suggest the relationship between physical components of surprise, fear and anger in each facial image and facial distinctiveness. |
