Message = 'You did not hit the button!' # Adding the ISI so it is saved in the datafile # We count the duration of the feedback as part of the ISI # If it is the first trial if PVT_Trials.thisN = 0: RandISI = random() * (maxISI - minISI) + minISI In the next tab (“Begin Routine”), we will add code that is changed every time this routine starts: # ISI is then set each routine The last two variables are not used in this particular routine, but we will use a warning sound (a beep) that will be played when not responding (the timer is used for this as well). Hopefully, the variable names are self-explanatory (with the comments in the code), but it is the ISI, feedback duration, and task. Note that all durations are in seconds so this psychomotor vigilance task might be rather short (i.e., 3 minutes), and you can change this for your own needs. Here is the code we add: # All the durations are in seconds # Random ISI between 1 and 4. We could have added this to a code component in a previous routine, but we had no use for other code segments then. In the first tab (“Being Experiment”), we will add some of the settings of the Psychomotor vigilance test: the ISI, the task’s duration, and the task’s duration. In this post, we use the PsychoPy 2022.1.4 version:ĭo not worry we will get into more detail than this (also, you can download the Psychomotor vigilance task towards the end of the post to look). ![]() In this section, we will start by opening the PsychoPy application and then build the Psychomotor vigilance test step-by-step. How to Create a Psychomotor Vigilance Task with PsychoPy We will go through how to create routines, add text stimuli, keyboard responses, and custom Python code, among other things. In this post, we will create the Psychomotor vigilance task using PsychoPy. To download and find instructions on how to install PsychoPy, click here. To follow this PsychoPy tutorial, you need to have an installed version of PsychoPy and some minimal knowledge of Python language (if you want to customize your experiment a bit).
