Note that the text output for cases where you store the mouse data repeatedly per trial (e.g. How often do you need to save the state of the mouse? Every time the subject presses a mouse button, at the end of the trial, or every single frame? What information to save, how to lay it out and when to save it. If this box is checked then the Routine will end as soon as one of the mouse buttons is pressed. See Defining the onset/duration of components for details. The time that the mouse should first be checked. The name should contain only letters, numbers and underscores (no punctuation marks or spaces). Tracking the entire path of the mouse during a period Parameters ¶ name stringĮverything in a PsychoPy ® experiment needs a unique name. X position of the mouse to control the size or $mouse.getPos() to use the y position. Then for the size setting of your Patch stimulus insert $mouse.getPos() to use the Imagine you want to use your mouse to make your ‘patch’_ bigger or smaller and save the final size.Ĭall your mouse ‘mouse’, set it to save its state at the end of the trial and set the button press toĮnd the Routine. Use the mouse to record the location of a button press Use the mouse to control stimulus parameters Here are some scenarios (email the list if you have other uses for your mouse): Given in the same coordinates as the Window, with (0,0) in the centre. The coordinates of the mouse location are See the API for iolab.The Mouse component can be used to collect responses from a participant. Using code components, it is possible to turn on and off specific lights within a trial. If selected, the lights above the active buttons will be turned on. If selected, all lights will be turned off at the end of each routine. If selected, any previous responses will be ignored (typically this is what you want). If selected, a correctness value will be saved in the data file, based on a match with the given correct answer. Events and the response times are saved, with RT being recorded by the button box (not by PsychoPy ®). Which button events to save in the data file. Store (choice of: first, last, all, nothing) This field lets you specify which buttons (None, or some or all of 0 through 7). Responses on non-active buttons are ignored by the box, and never sent to PsychoPy ®. The ioLabs box lets you specify a set of active buttons. Active buttons None, or an integer, list, or tuple of integers 0-7 If this is checked, the first response will end the routine. The duration for which the stimulus is presented. The time that the stimulus should first appear. Properties ¶ name stringĮverything in a PsychoPy ® experiment needs a unique name. The ioLabs button box also has a built-in voice-key, but PsychoPy ® does not have an interface for it. It might be possible for you to obtain a correction factor for your computer + button box set up, if the timing delay is highly reliable. If this takes a while, then the RT timing values are not likely to be high precision. This is what makes it capable (in theory) of high precision timing.Ĭheck the log file to see how long it takes for PsychoPy ® to reset the button box’s internal clock. The time taken is determined by a clock on the device itself. A button box is a hardware device that is used to collect participant responses with high temporal precision, ideally with true ms accuracy.īoth the response (which button was pressed) and time taken to make it are returned.
