Presentation version 17

The doors task (25 (link)) was administered using Presentation, version 17.2 (Neurobehavioral Systems, Berkeley, CA, USA) and consisted of three blocks of 20 trials. Each trial began by presenting two identical doors. Participants were instructed to select the left or right door by clicking the left or right mouse button, respectively. Participants were told that they could either win $0.50 or lose $0.25 on each trial. The image of the doors was presented until participants made a selection. Next, a fixation cross was presented for 1000 ms, and feedback was subsequently presented for 2000 ms. A monetary gain was indicated by a green arrow pointing upward and a monetary loss by a red arrow pointing downward. The feedback stimulus was followed by a fixation cross presented for 1500 ms, immediately followed by the message “Click for next round.” This prompt remained on the screen until participants responded with a button press to initiate the next trial, ensuring that participants remained active and engaged during the task. There were 30 gain and 30 loss trials.

The doors task was administered on a computer via Presentation, version 17.2 (Neurobehavioral Systems, Albany, Calif.), and consists of three 20-trial blocks. Each trial began with two identical doors presented on the screen. Participants were told that they could either win $0.50 or lose $0.25 on each trial and were asked to select the right or left door by clicking the right or left mouse, respectively. Rewards trials are twice as large in magnitude compared to loss trials because losses are subjectively about twice as valuable as gains (Tversky & Kahneman, 1992 ), while also ensuring that participants accrue money over the course of the task. The doors were presented on the screen until the participant made a selection. Following the participant’s selection, a fixation cross was presented for 1000 ms, and feedback was subsequently presented for 2000 ms. A green arrow pointing upward represented a gain, whereas a red arrow pointing downward indicated a loss. The feedback, which was randomly determined, was followed by a fixation cross presented for 1500 ms, subsequently followed by the message “Click for next round”. In order to ensure that participants remained engaged, the “Click for next round” message remained on the screen until the participant responded to begin the next trial. All participants received 30 gain and 30 loss trials.

The Doors task is a simple monetary reward task in which gains and losses are equiprobable on each trial (Proudfit, 2015 (link)). Using the left and right mouse buttons, participants were instructed to select between two identical doors displayed on a computer screen. After making a selection, a fixation cross was presented for 1500 ms, followed by feedback stimuli that indicated whether they won (i.e., a green arrow pointing upward signified +$0.50) or lost (a red arrow pointing downward signified -$0.25) on that trial. The feedback stimuli remained on the screen for 2000 ms. Text appeared on the screen that instructed participants to “Click for next round”, followed by a fixation cross presented for 1000 ms. The task contained 30 gain trials and 30 loss trials that were presented in pseudo-random order, using Presentation, version 17.2 (Neurobehavioral Systems, Albany, Calif.). Participants were told that they could receive between $0 to $15 dollars at the end of the task based on their cumulative earnings; all participants received $8 for completing the task.

Participants were told that they could receive between $0 to $15 dollars (rounding up) at the end of the task based on their cumulative earnings; all participants received $8 for completing the task.
