You’ll also want to create a new Keyboard that starts at zero and goes on until a key is pressed (leave duration blank and check Force end of Routine).

Then you want to create a new Text stimuli that starts and zero and has an infinite duration (leave duration blank) and have the text say You’ll then want to move the dot that appears to the left of our trials loop (make sure it’s outside the loop, we don’t want it to appear every time a new word is going to be shown). Down in the Flow bar click Insert Routine -> (new) and name the new routine instructions. We probably want to give the subjects some form of instruction for taking the test so we’ll do this by adding a new routine to the experiment. You should go back into the Keyboard response and set the Allowed keys $ to be ‘left’, ‘right’, ‘down’ and the Correct answer to $corrAns and make sure that Store correct is checked off. The dollar sign signifies that this value is a variable so PsychoPy knows to go into the conditions file to get a value to replace it. Now that you have imported a conditions file your going to want to go back into your Text object target and set the Color equal to $color and the Text to $word. We’ll also want to set nReps $ to 1 so that it only goes through all the conditions in the file once. We’ll want to go back into the loop from earlier and browse for the conditions.xlsx file. You cannot have any spaces in your column names or data in PsychoPy and it will give you a warning if you try to use a file that does. Creating ConditionsĬonditions files for PsychoPy are made using Excel so you’ll want to make a table that matches this and save it as conditions.xlsx (it must be in the. We’re going to want to make a conditions file for our loop as well. We’ll name our loop trials and set its type to be random.

Adding a LoopĪt the bottom of the window there is a Flow bar, under this we’re going to select Insert Loop and move the dot that appears after trial in the flow diagram. You can also add responses from the lab microphones or mice. We’ll also check the Force end of Routine box so that once it receives input, the program moves onto the next stimuli. We’re going to name our Keyboard response and have it start at 0.5 seconds and make the duration blank so that it will accept input infinitely. Over in the component bar we’re going to select Responses -> Keyboard to allow the subject to respond to the text. You can click the Text icon on the timeline to change its properties in the future.

For now we don’t need to change anything else about our Text so hit OK and the object should appear on the experiment timeline. We’re going to set the Name of our Text object to “target” and set the start time to 0.5 seconds and the duration of the Text to 4 seconds.

Note that you can hover over the green plus sign on each icon for a brief explanation of what it does and that you can add other stimuli such as sound or images. In our case we want to select Stimuli -> Text (the icon with two Ts) which will open a window where you can change various aspects of the text. In the right sidebar of the Builder window, you can select what components you want to add to your experiment.

When you open PsychoPy two windows will show up the Builder window and the Coder window, we will only be using the Builder window in this tutorial. It can be used to present a subject with a variety of audiovisual stimuli and record their responses to that stimuli.Ī simple experiment we can create in PsychoPy is Stroop, which is detailed in this tutorial on YouTube and written below. PyschoPy gives a graphical interface to the programming language Python in order to make it easy for people to generate their own experiments.
