Inhibition of return is an inhibitory mechanism which refers to the position previously noticed showing slower response.Providing neural, positive and negative facial images as target stimulus, subjects were asked to perform detection task with ERPs technology. It was found that the data on the behavior and EEG record had significant IOR effect. According to EEG results, no effects on the component of P1 were found. However, the effect of IOR were found on N1 and N170. Compared with amplitude of the invalid cues, we found that the amplitude of N1 of the valid cues was larger, while the amplitude of N170 was smaller.Interestingly, there are emotion effect of N1, indicating that emotional face induced more attentional bias than neural face. More surprisingly, we found a significant interaction effect between emotion values and IOR. The simple effect showed that the amplitude of emotional face was larger than neural face. These results indicate that IOR at least partly arises from changes in perceptual process, and to a certain degree, implicit emotion process can modulate IOR.
