BEHAVIORAL - Effects of tDCS of dlPFC on Probabilistic Selection Task
Sham comparator: tDCS sham - Transcranial direct current stimulation (tDCS) of the dorsolateral prefrontal cortex (dlPFC) in sham mode.
Active comparator: tDCS anodal - Transcranial direct current stimulation (tDCS) of the dorsolateral prefrontal cortex (dlPFC) in anodal/excitatory mode.

Summary
Brief summary
The project aims to investigate whether tDCS has an effect on reward and punishment learning sensitivity. Further, whether tDCS will modulate extraversion and impulsivity personality traits, and eye-blink-rate's effect on learning. For instance, trait extroversion in past research is linked to the dopamine neurotransmitter system, where it is thought that extreme low and high levels are detrimental to cognitive performance. Since tDCS has been shown to increase dopamine levels, it is thought that people who are already high in dopamine may experience less benefit (or even impairment) on cognitive performance following tDCS.
