For example, suppose you want to check whether the particpant pressed the spacebar. Importantly, one common thing in working with keypresses is that you want to check whether a particular key was pressed. TDown: a float with the abolute time (in seconds unlikely you ever need this) ĭuration: a float with the time (in seconds) the key was pressed in (or None if still pressed in)

Rt: a float with the time (in seconds) from start of the Keyboard clock (i.e., the clock attribute) Name: a string with the name of the pressed key (e.g., 'a', 'b', 'return', 'left', etc.) In fact, these KeyPress objects contain much more information that is contained in its attributes: Then, run the experiment and check the Experiment runner to see the printed output.Īs you can see, the getKeys method specifically returns a list of KeyPress objects! These objects are not just strings corresponding to the pressed keys (e.g., “a”, “b”, “return”, “left”, etc.), as you might expect.

Check out PsychoPy’s reference manual for a complete overview of the package’s modules.Īs you will see, most of PsychoPy’s functionality (like the different components) is implemented in custom classes, so your experience with object-oriented programming as discussed in week 1 will be very useful!Īfter the initialization of the Keyboard object and the call to wait (from the previous ToDo), call the getKeys function and store the result in a variable (e.g., keys) and print this variable.

For example, the visual module contains a class to specify and create a window and a large set of visual components (like text, image, and movie components) and the event module contains code to work with “events” such as mouse clicks/movement and keyboard presses.

The psychopy package contains different modules for different features. However, as mentioned on the Getting started page, getting the psychopy package to work is not easy, which is why we recommend the “batteries included” standalone version of PsychoPy. Often this correct answer will be defined in the settings of the Loops.If you plan on programming your PsychoPy experiment (so not use the Builder interface), you technically do not need the entire “standalone” PsychoPy package installing the psychopy Python package would suffice and you could just write your experiments in your favorite editor (like Visual Studio Code). This is given as Python code that should return True (1) or False (0). 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 :Ĭheck this box if you wish to store whether or not this button press was correct.

if the joyButtons was initiated 2 seconds into the trial and a button 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 joyButtons checking (e.g. The response time will also be stored if a button press is recorded. If the button press is to force the end of the trial then this setting is unlikely to be necessary, unless two buttons happen to be pressed in the same video frame. Which button press, if any, should be stored the first to be pressed, the last to be pressed or all that have been pressed. Note that button numbers (0, 1, 2, 3, …), should be separated by commas. Only allowed buttons count as having been pressed any other button will not be stored and will not force the end of the Routine. If this box is left blank then any button that is pressed will be read. , or the name of a variable holding such a list. Allowed buttons :Ī list of allowed buttons can be specified here, e.g.
