Face capture more attentional resource than No-face Object: An ERP study

This study want to find electrophysiological evidence to test whether face capture more attention than object, and whether the attention capture of face automatically or controllably. Fifteen subjects were tested on a three-stimulus visual oddball task, in which faces and objects as distractor stimuli were presented in different blocks separately. Face as task-irrelevant stimuli elicited earlier, greater and frontal-distributed P3a, which suggests that faces can faster capture more attention than object automatically. And we infer that face and object as distractor stimuli are processed in different brain mechanisms.
