These tasks are Gorilla implementations of the auditory and visual simple reaction time tasks described in Hintz et al. (2020). They are shared with permission from the original authors. Descriptions of each task can be found under their respective headings. In these tasks, participants press a button as soon as they perceive the stimulus that is presented, which is either a tone or a drawing of a triangle.
Note that the instructions are in Dutch! Also note that we have uploaded two versions of the auditory task and one version of the visual task. There are two versions of the auditory task because, in the original tasks we copied from Hintz et al. (2020), the duration of the wait period before the stimulus was shown was generated in a completely random fashion (but always between 1 and 3 seconds long). In other words, it was different for each trial and each participant. We used this same design when our aim was to compare data collected online to Hintz et al.'s (2020) lab-based data. However, for individual differences designs, it is better if the task is as consistent across participants as possible. We have, therefore, also uploaded a version of the auditory task in which we randomly generated the wait periods upfront and presented these in the same order for each participant. In this version of the task, we also removed the fixation cross, since we asked a group of blind participants to complete it too.
Built with Task Builder 1
This is the implementation of the original auditory simple reaction time task as described by Hintz et al. (2020).
Each trial of the A-SRT began with the presentation of the fixation cross, which now remained in view until participants responded. One to three seconds after trial onset (varying interval), a sine tone (550 Hz, 400 ms) was played. Participants pressed the right-hand button on their button box as soon as they heard the tone. This terminated the trial. After one second, the next trial began. The test consisted of a practice block of eight trials followed by 20 test trials. As in the V-SRT, participants’ score was their average RT on test trials.

Built with Task Builder 1
This is our implementation of the auditory simple reaction time task, with fixed (but randomly generated) wait periods before the stimulus is presented and no fixation cross.
Note also that this version (unnecessarily, but just in case) includes a pre-loading script that loads all auditory and visual stimuli before a task starts, so that participants do not encounter loading delays during the task.

Built with Task Builder 1
This is the implementation of the original visual simple reaction time task described by Hintz et al. (2020).
On each trial, participants first saw a fixation cross in the center of the screen. After an interval varying randomly between one and three seconds, it was replaced by a line drawing of a triangle (200 × 200 pixels, black contours). Participants were instructed to press the right-hand button on their button box as soon as the triangle appeared. The response terminated the trial. After a blank interval of one second, the next trial began. The task consisted of eight practice trials followed by 20 test trials. Participants’ score was their average RT on test trials.
