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. For most experiments this box should be checked.Now we’re going to walk through how to use PsychoPy, from installation to experiment with descriptions of the most important features. If this box is not checked a keyboard press that has occurred before the start of the checking period will be interpreted as the first keyboard press. Discard previous Check this box to ensure that only key presses that occur during this keyboard checking period are used. Often this correct answer will be defined in the settings of the Loops.

This is given as Python code that should return True (1) or False (0). left, 1 or $corrAns (note this should not be in inverted commas). If so then fill in the next box that defines what would constitute a correct answer e.g. Store correct Check this box if you wish to store whether or not this key press was correct.

if the keyboard was initiated 2 seconds into the trial and a key was pressed 3.2s into the trials the response time will be recorded as 1.2s). This time will be taken from the start of keyboard checking (e.g. The response time will also be stored if a keypress is recorded. If the key press is to force the end of the trial then this setting is unlikely to be necessary, unless two keys happen to be pressed in the same video frame. Store Which key press, if any, should be stored the first to be pressed, the last to be pressed or all that have been pressed. To find other special keys, run the Coder Input demo, “what_key.py”, press the key, and check the Coder output window. Cursor control keys can be accessed with ‘up’, ‘down’, and so on the space bar is ‘space’. Note that key names (even for number keys) should be given in single quotes, separated by commas. Only allowed keys count as having been pressed any other key will not be stored and will not force the end of the Routine. If this box is left blank then any key that is pressed will be read. , or the name of a variable holding such a list. Allowed keys A list of allowed keys can be specified here, e.g. Force end routine If this box is checked then the Routine will end as soon as one of the allowed keys is pressed. See Defining the onset/duration of components for details. Stop : When the keyboard is no longer checked. Start : float or integer The time that the keyboard should first get checked. The name should contain only letters, numbers and underscores (no punctuation marks or spaces). Parameters ¶ Name : string Everything in a PsychoPy experiment needs a unique name.
