Exemplary timeline trial of the adapted version of the TLCG with a politician as prime stimulus. At the beginning of each trial, participants started to play by pressing the spacebar, which caused the prime stimulus to appear on the screen for 1000 ms. The stimulus could either be the image of a politician (366 × 492 pixels) or an ideological word (685 × 180 pixels). A fixation cross (500 ms) appeared before the card (190 × 300 pixels) referred to the outcome of the game and the card (190 × 300 pixels) representing the opponent's status were revealed. The two cards stayed on the screen for 1500 ms before the participants were able to decide whether to lie or tell the truth to the opponents. They did so by pressing either the “M” or “V” buttons on the keyboard, respectively. There was no time limit to make this choice. Then, 800 ms after deciding, the picture of the opponent appeared on the screen, where it stayed for 1500 ms. In the present figure the images of the politician and the opponent are presented anonymously. The figure was created by the authors.
