In the code above, we first calculate the random ISI for each trial (i.e., each routine). ThisExp.addData( 'ISI', randISI) Code language: Python ( python ) 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.

How to Create a Psychomotor Vigilance Task with PsychoPy.

If a user wants to add support for a particular stimulus, analysis or hardware device they can look at the code for existing examples, modify them and submit the modifications back into the package so that the whole community benefits. Most importantly, PsychoPy is highly extensible and the whole system can evolve via user contributions. Tools are provided within the package to allow everything from stimulus presentation and response collection (from a wide range of devices) to simple data analysis such as psychometric function fitting. PsychoPy scripts are designed to be extremely easy to read and write, while retaining complete power for the user to customize the stimuli and environment. PsychoPy is a platform-independent experimental control system written in the Python interpreted language using entirely free libraries.

The current paper describes a new free suite of software tools designed to make this task easier, using the latest advances in hardware and software. The vast majority of studies into visual processing are conducted using computer display technology.
