Design of the experiment.

<p>(a) For the first trial and trial following the break, subjects had to fix a cross while making their selection by pressing a key. (b) Selection was followed by a feedback of the deck chosen and the total credit amount. (c) Then the money involved in this trial was displayed. (d) A fixation point appeared to focus the eyes, followed by a fixation letter announcing the result. Half of subjects (5 men/5 women) received the information that (e) the letter P means loss (“Perdu” means loss) and (f) letter V means win (“Victoire” means victory), and the other half received the opposite information.
