[P1-03] Temporal asymmetry of effects of fearful and disgusted faces on attentional blink
Keywords:Negative emotion, Facial expression, Attentional blink
Many studies have reported that each facial expression stimulus affected differently visual attention in the various properties. In temporal properties, primed fearful faces facilitate second target (T2) detection in attentional blink. On the other hand, primed disgusted faces reduce T2 detection. However, the different effects of the inserted facial expression stimuli have not examined yet between fearful and disgusted faces. The present study compared the T2 (neutral face) identification performance when fearful, disgusted, and neutral faces were presented as first target (T1). The results indicated that T2 accuracy was higher when T1 was disgusted face than other faces in lag-1. On the other hand, T2 accuracy was higher when T1 was fearful face than other faces in lag-6 and lag-1. Thus, the effects of facial expression in visual attention differ temporally between fearful and disgusted faces.
