Employing a behavioral paradigm combined with the ERP technique, the present research is aimed at exploring how endogenous orienting of visual attention influenced depth processing and how it was expressed in ERP components. Main conclusions are as follows: At both the short and the long SOA, the predictive central symbolic cue produced a facilitative effect on the subsequent discrimination task in the 3D condition, and the difference between the two treatments was not statistically significant. At the short SOA, both the classic and the cross-depth facilitative effect in stereoscopic space affected N1 wave of ERP early components, in which the valid-cue trials induced a larger N1 amplitude; while at the long SOA, the invalid-cue trials tended to induce a larger N1 amplitude.
