ABSTRACT
Non-invasive brain stimulation techniques,including transcranial direct current stimula-tion (TDCS) and transcranial magnetic stimulation (TMS),are safe and non-invasive techniques,which can change the local excitability of the brain. The application of these techniques in the field of psychology,espe-cially decision making,has developed rapidly. These techniques provide the researchers a new perspective to study how people make decisions and to explore the neural mechanisms behind decision-making behaviors. This paper reviews the studies of non-invasive brain stimulation techniques in the field of different decision-making behaviors (risky choice,intertemporal choice and social decision-making) and the problems existing in the current studies,and puts forward some possible solutions.
