all would receive an extra reward of €100. After completion of the BART, participants were disconnected from the EEG. They were given a final subjective measure of alcohol effects and BAC level was measured for the fourth time. Participants were then instructed to remain in the university building and had to go to the refectory to eat and drink something. After 45 min (i.e., 2 h after beverage administration), participants had to return to the laboratory to monitor their final BAC and participants were allowed to leave once their BAC fell to 20 mg/100 ml or below. All participants received a small financial reward or course credits for their participation, and they were instructed not to drive a vehicle after the experiment. The study was conducted in accordance with the Declaration of Helsinki and approved by the ethics committee of the Institute of Psychology of the Erasmus University Rotterdam.
