Eye Fixation-Related Potentials during Visual Search on Acquaintance and Newly-Learned Faces
Searching familiar faces in the crowd may involve stimulus-driven attention by emotional significance, together with goal-directed attention due to task-relevant needs. The present study investigated the effect of familiarity on attentional processes by exploring eye fixation-related potentials (EFR...
