Inclusion criteria
Inclusion criteria: All participants are all right handed, have normal or corrected-to-normal vision, and no color vision deficiency, psychiatry disorders, and neurological disorders. For EEG/ERP and fNIRS experiments combined with neuromodulation (tDCS/TMS), all participants should fit the above criteria and they also need to pass all imaging-neuromodulation safety check: 1.Participants should not have major surgery before. Participants with minor surgeries 6 months before, such as extract a wisdom tooth, may participate in EEG/ERP/fNIRS and neuromodulation experiments after the evaluation of the experimenters. Participants with minor surgeries 6 months before may participate in fMRI experiments after the evaluation of the experimenters and the staffs of the MRI imaging center. 2.Participants should not have any implants in the body, including cochlear implant, Hearing Aid, Shrapnel, pacemaker, artificial/prosthetic heart valve, implanted cardioverter defibrillator (ICD), coronary stent, aneurysm clips, Aortic Clips, Brain Clips, Carotid Clips, Shunts, Electrodes, joint replacements, pins or wires, magnetically-activated implant or device, Metal Mesh, Metal Rods,Plates, Screws, neurostimulation system, spinal cord stimulator, insulin or infusion pump, implanted pump (e.g., drug infusion pump), bone growth/bone fusion stimulator, any type of prosthesis (e.g., artificial eyeballs, penile implant, artificial limbs, and dentures), heart valve prosthesis, eyelid spring or wire, Permanent Eyeliner, metallic stent, filter or coil, shunt (spinal or intraventricular), vascular access port and/or catheter, wire mesh implant, bone/joint pin, screw, nail, wire, plate etc., other electronic implants or devices, any internal electrodes or wires. 3.Participants should not have artificial limb, calliper or surgical corset in the body. 4.Participants should not have any shrapnel or metal fragments in the body and do not have worked in metal environment. 5.Participants should not have claustrophobia (it is not suitable for EEG/ERP experiment and neuromodulation trials). 6.Participants should not have nephritis or nephropathy. 7.Participants should not have history of head trauma. 8.Participants should not have menieres disease. 9.Participants should not have injury to eyes (involving metal). 10.Participants should not being pregnancy or should not in breast feeding . 11.Participants should not have stroke/seizure. 12.Participants should not have tattoos and do not have hair coloring (it is not suitable for EEG/ERP experiment and 13.neuromodulation trials). 14.Participants should not make up before experiment.
