The executive function is a set of higher-level cognitive abilities that control a high level of behavior. The executive function acts in a variety of contexts differently, including the function of the hot type that evoked in areas that are influenced by emotion, motivation, and reward. The present s tudy was performed to inves tigate the effects of transcranial direct current s timulation (tDCS) on the left dorsolateral prefrontal cortex (DLPFC) on hot executive function. Materials and
more » ... : The s tudy was a single-blind experimental s tudy performed on 30 healthy adults. In this s tudy, subjects were randomly divided into two experimental and control groups. In the experimental group, anodal s timulation over the left DLPFC and cathodal s timulation over the right OFC were performed at 2 mA. The tasks used were computer versions of the Balloon Analogue Risk Task and the Iowa Gambling Task for evaluating decision making and risk-taking. Results: A significant difference was observed between the experimental and control groups in the Bart tes t. There was difference between the two groups in the Iowa tes t. Conclusion: tDCS anodic s timulation can increase the hot executive functions in decision making.
