The main window (b.) shows the content of a single routine. In the above example there is only one routine called “trial”. The Flow is the bottom part of the builder window (a.) and shows the order of all your routines. One way of thinking of these routines are as individual slides in a slideshow. PsychoPy experiments are built together by assembling Routines or modules which each have a certain function. The above Figure 1 shows the basic layout of the Builder View. PsychoPy experiment files will end in the extension “.psyexp”.įigure 1 – Example of PsychoPy Builder Window Then, save your blank experiment in a folder. On windows, this will open the PsychoPy builder window as well as a command line window running python which you need to leave open. Once installed, open up PsychoPy to begin a new experiment. We recommend choosing the Standalone option, as this includes all the relevant dependencies and is the most hassle-free option. The first step is to choose your installation. Throughout this tutorial we’ll be giving examples in a Windows environment, but processes for Linux or Mac environments are comparable. If your specific type of task isn’t listed in the examples, experiment with the builder yourself and see if you can figure out how to make it work for you! Also consider referencing the PsychoPy manual and various message boards and forums for answers to your questions. Print("Experiment saved as:",'experiment_' + str(()) + '.Now we’re going to walk through how to use PsychoPy, from installation to experiment with descriptions of the most important features. Pd.DataFrame(data,columns=).to_csv('experiment_' + str(()) + '.csv') Print("You pressed the seconds".format(key,round(time,3)))įinally we put everything together and save the file as a CSV using pandas def main(): We reset it on every iteration and show each screen every time. We create the clock that measures the time. Here we implement the main logic of the program. Msg1 = visual.TextStim(win, text="press any key to start", color=white, colorSpace='hex') # Elements are only displayed after the flip command is executedīackground = visual.Rect(win, width=resolution+10, height=resolution+10, fillColor=gray, fillColorSpace='hex') Msg2 = visual.TextStim(win, text="press to continue", color=white, colorSpace='hex',alignHoriz='center', alignVert='center') Msg1 = visual.TextStim(win, text="press to exit", pos=(0.0,(-resolution*0.10)), color=white, colorSpace='hex') Our program has only two screens, the starter screen that ask you to start, and the stop screen that records how long you took to press the button.īackground = visual.Rect(win, width=resolution+10, height=resolution+10, fillColor=black, fillColorSpace='hex') Here we will specify the text messages, its style, the background colour and all that kind of things. Win = visual.Window(resolution,units="pix", color=gray, colorSpace='hex', fullscr=fullScreen, monitor = "testMonitor") In psychopy you define the window where all the screens are going to be displayed like this def window(resolution): Setting constants and global variables # Colours ![]() Import pandas as pd # Used to save the data as csv easily Import datetime # Used to register the date of the experiment The full code can be found here.įirst I import the libraries from psychopy import visual, core, event ![]() In this example I will show how to develop a basic experiment that registers how much time it takes for someone to press a key, then I will save the data as a csv file. Psychopy library is a useful framework to develop psychological experiments using Python.
