Schematic depiction of the paradigm. Each trial started with a fixation cross, which was followed by one of three Gabor patches corresponding each to a specific condition. Both (a) reward condition and (b) neutral condition were followed by a light flash to which participants had to respond as fast as possible. Based on the speed of the response a specific feedback was provided indicating if the participant was fast enough or too slow. Given the chance to win 1 euro per trial in the reward condition, the cumulative total win was presented only in this condition. (c) was the control condition in which only the Gabor patch was presented and no response was required.
